Dr. Collier’s passion for medicine originated at a young age. She is a twin and was fascinated by how her sister and she could look so much alike. Her quest for answers took her to medicine. During her dermatology rotation at the end of her fourth year of medical school, she worked in adult and pediatric dermatology clinics and saw firsthand how conditions like vitiligo, psoriasis, acne, keloids and skin cancer can be devastating to person’s health, self-image, and overall quality of life. “This motivated me to pursue a career in dermatology so I may treat these conditions and improve someone’s life,” she says. Dr. Collier looks forward to providing excellent medical care to the community members.

Good Visit
February 03, 2026
It was a good experience for the most part the scary part was the elevator I know it's weird to say but other than that I had a good experience Dr Avanta Collier was nice and professional she did her job accordingly she was very courteous and polite she asked me questions she listened to me she didn't brushing me off he didn't rush she took her time the nurses were very polite and nice everyone there did their job they were very professional and nice and it was a good clean atmosphere I was a nervous going in but what made me nervous was the elevator it was quickly and it kind of scared me and small and I'll do well in small spaces but anyway the nurses and Dr.Collier took their time with me and gave me time to do my paperwork since I was a new patient and I appreciate it the time they took out to let me get myself relaxed and calm I really do appreciate it and my experience overall was great!
January 28, 2026
Dr. Collier did a great job. I really appreciate her. I've been seeing her for years. I accidentally pressed one for the, would you advise other family members to see her? I would absolutely advise other family members to see her. She is an excellent doctor and I appreciate her over the years. Thank you very much.
January 26, 2026
Doctor and all nurses and personal took excellent care of me, thank you
January 26, 2026
Very efficient process to freeze suspect spots and take biopsies. Doctor listened to my concerns about suspect areas. Very pleased with visit.
January 21, 2026
Dr Collier is AMAZING!
January 14, 2026
Dr. Collier made my biopsy pain-free virtually and it was very simple, something I wasn't looking forward to, but something that was done with no pain and very quickly and I thank her for that. Also, I would love to get a response as to the results as soon as possible because, of course, it's scary. Thank you. (PHI removed).
January 14, 2026
Okay, I think I mis pressed a button. So yes, I would definitely recommend this doctor and this care to my family. I think I pressed one when I meant to press ten. I think I messed that up. Anyhow, aside from that, there was a glitch in 2025 January. Your computer systems got hacked. I think I got lost for a year, and that's too bad. I wish I would have gotten a call back or something more permanent, but however, the computer system recommended me for another appointment, in which I kept. So that worked out. Just if you lose contact with patients, reach out to them. They're your patients. They belong to you, kind of. Anyhow, take care. Thank you. Thank you.
January 05, 2026
Friendly, knowledgeable and professional staff.
January 05, 2026
It's hard to believe that getting skin tags removed is considered cosmetic by PIH and that I would likely have to pay for them if my insurance didn't cover it. Especially if the skin tags are in an area where they get irritated and grow bigger
December 30, 2025
Dr. Collier was courteous, friendly, respectful, listened to what I had to say, treated my issue on the spot, gave instructions before I left.
December 30, 2025
She was professional, kind and knowledgeable
December 15, 2025
The only thing I might suggest is if the front office is aware that the waiting room can hear their personal conversations they have.
December 15, 2025
Upon my arrival the front desk clerk was on a personal call that last approximately 10 mins (She was speaking Spanish to a family member) and delayed my ability to see the physician. In the background I noticed that the back office assistant/nurse was waiting for me to get checked in.
December 15, 2025
Doctor Collier was very professional and kind.
December 10, 2025
On my very last answer, I meant to put four.
December 09, 2025
Dr. Collier and the staff at the La Mirada office are always wonderful!
December 09, 2025
The doctor and her assistant were friendly and professional. The doctor is very warm and welcoming and explained things extremely well. I wish she was my primary doctor.
December 09, 2025
Doctors staff and doctor were excellent however front doors not working and 1 out of 2 elevators not working
December 03, 2025
Staff is welcoming and cordial. I see the dr monthly and make my appt 3-6 months out. Dr Collier is always warm and sensitive to my needs. I appreciate the ease of accessing the La Mirada office. All this combined makes my experience enjoyable.
December 03, 2025
I was safe and in good hands. Dr Collier does not marginalized seniors. I felt that instantly when meeting her.
December 02, 2025
Dr. Collier is always professional, friendly, and just a great doctor. Thank you very much.
December 02, 2025
Great (name removed) thank you for everything
December 01, 2025
I've been going with Dr. Collier for probably about three or four years, and she has been an excellent, excellent physician. I would recommend her for all of my dermatology care and any of my friends, and I just think she is absolutely fantastic. I have seen other dermatologists at PIH, and I will only go to her. That's the only one I will go to. I think she is fantastic, absolutely fantastic. And she listens to me, absolutely listens to me. So I think she is a top-notch doctor. And I am a registered nurse for over 50 years, and I have worked with dermatologists. So I know what to ask and what to look for. And she is everything. She is a top-notch doctor. Amen.
November 18, 2025
Dr. Collier is caring and thorough. I'd recommend her to anyone.
November 18, 2025
I am highly satisfied about this visit to my Dermatologist. She is very courteous, knowledgeable and spent sufficient time with me to explain about my condition and have suggested and set up further Required treatments and visits. I sincerely am thankful to her and PIH Health Physicians. God bless you all
November 17, 2025
One elevator in the building was out of order and made for a lengthy wait; also the restroom in the Dr. ofc was out of order. These two incidents made my experience a little troublesome, however as far as my experience with Dr. Collier was very pleasant and professional. She is such a sweetheart!
November 11, 2025
The doctor answered all the questions that I had. I learned a lot about my condition, helpful.
November 10, 2025
Yes, Dr. (name removed) and staff were very friendly, professional, efficient. I would recommend them to anybody. Thank you. Bye-bye.

October 22, 2025
Great job
October 22, 2025
Dr Collier was wonderful. She listened and did a couple of small procedures I've been wanting done for years. I appreciate her very much.
October 21, 2025
Yeah, yes, I had a nice visit with the doctor and she seemed very thorough. Thank you.
October 21, 2025
Wonderful doctor and staff. All seemed genuinely happy and caring. 10 of 10.
October 20, 2025
Dr. Collier MD, Avanta, and her staff Is always amazing. The best Dermatologist I've seen. I like her feedback and the way she care for her patients. I would definitely recommend her to family and friends.
October 15, 2025
The doctor's care was very good.
October 15, 2025
Dr. Collier is excellent. She is friendly, knowledgeable, and kind. She was able to diagnose my problems right away and suggest new treatment that would be more beneficial than what I had tried. I appreciate her concern and care. Of note: I had to wait almost six months for this appointment, which is not acceptable. My follow-up visit months from now was difficult to book due to a full schedule. Perhaps more physicians are needed for this specialty? Or PAs or NPs? The waits are far too long.
October 15, 2025
35 min wait after appt time due to multiple patients scheduled at the same appt time. I know you have to make money but you have to respect our time too!!
October 07, 2025
while the office staff was very friendly. The reason I didn't answer all 10's on survey is because I feel that I'm sure she's qualified as a Dermatologist, however in my case, I didn't really understand why she was not able to do anything for me and referred me to another Dermatologist. I was feeling good about seeing her and that I wouldn't have to start over with another provider.
October 06, 2025
Dr is very knowledgeable and understanding
October 06, 2025
Dr. Collier is always very professional, very friendly, helpful, informative, and it's always a pleasure to see her.
October 06, 2025
This provider was not very thorough in examining me and didn't explain or provide any information or feedback. She seemed preoccupied and was in a rush. The office staff is not welcoming or friendly at all. This was not a good experience.
October 01, 2025
Dr Collier is a wonderful Doctor. I wish my daughter could see her- unfortunately her insurance is with a different company.
September 30, 2025
The office visit was scheduled for 10, 30 a.m. and I didn't get seen till 45 minutes later. I would have preferred to be seen a lot sooner than that, understanding that we had a scheduled appointment and I was on a standard workday. So I gauged my time with the office in accordance with that. And unfortunately, it overran the expected time to be there. The office staff was very good. The doctor was outstanding. It was the timing in which I was seen that is in question. My information is provided. Call back to (PHI removed). I can expand further on that if you would like.
September 30, 2025
My experience was good. I got there a little early and was attended to within 15 minutes. Doctor treated me, explained my condition and I was done within 45 minutes.
September 23, 2025
Amazing team
September 23, 2025
Dr. Collier is always very proficient.
September 22, 2025
Everything went well at the doctor's office. I really love Dr. Collier. She's wonderful. I think very knowledgeable. The only thing that I see the issue is that it is very hard to get an appointment with her as soon as one wants it. It seems that there isn't enough doctors in the office, so the appointments are being set too far out. and that it's really not good. I almost considered going to another dermatologist because it was really hard to get an appointment with Dr. Collier. Thank you.
September 15, 2025
Dr. Collier and her staff were very nice. My issue is with how long it took to get an appointment with her. I called last May 1st to schedule an appointment and there first available appointment was on 9/15/25. That is unacceptable. I feel like PIH Health is failing it's patients with obviously a shortage of doctors.
September 09, 2025
I liked Dr Collier because she went straight to the point took care of my problem, explained everything did what she had to, and was very courteous, and respectful. Not like others that just gives you a little cream to see what happens.
September 02, 2025
There are not enough dermatologists available. The wait time to see one is months.
September 02, 2025
I have been under Dr. Collier's care for quite a few years now. She is very thorough and respectful. Her staff is very efficient and helpful.
August 20, 2025
Service is consistant in respect, courtesy, and the physician provides patient information in a kind and caring manner.
August 13, 2025
Dr. Collier was friendly and professional She gave me a thorough examination, noted several sites and discussed their significance with me. She also performed a biopsy. She is excellent.
August 13, 2025
My mole was froze but if it doesn't fall off in a while, I'll call doctor office to ask, how long it will take.
August 11, 2025
The customer was very, very honest, and she was very good at what she does. She helped us a lot, and we appreciate it, and we thank you.
August 11, 2025
Dr. Collier is helpful. She provided tips on how to care for my skin. I really appreciate her knowledge and her helpfulness.
August 06, 2025
Went to use the restroom and the lights didn't work
July 30, 2025
They have excellent staff. Thank you very much. I'm happy.
July 30, 2025
Dr Collier is very professional, knowledgeable and listens to solve concerns.
July 30, 2025
My doctor is professional and knows her work very well. The front desk staff are friendly and helpful! But I am unhappy the fact that it takes very long time to get appointments, no matter what doctor is needed. It is taking over 3 months to get appointments. This appointment with Dr. Collier was because there was a cancellation and lucky that I called. When I made my derma doc appointment, she was able in November. It was very necessary I needed to see her. Asked for any derma doc. None available. This was very frustrating because I was miserable! My only solution was I went to the pharmacist at CVS, recommended over the counter meds .. useless didn't work! Then I went to Urgent Care!!!! Soon after I had a regular appointment with my GP, he informed me wrong meds!!! Luckily there was a cancellation at my regular derma doc so I was able to see my dermatologist. My bone of contention is you please find a solution to this problem. I don't think the Emergency is the answer either. My experiences with this is the very long wait too!
July 29, 2025
My brother and my wife also see this provider based on my recommendation. Dr. Collier is thoroughly professional and personable. She listens and explains things clearly.
July 29, 2025
Love Doctor Collier
July 23, 2025
Wonderful Experience!!???????
July 23, 2025
First time meeting Dr. Collier and really enjoyed her bedside manner and good care of me. Thank you!
July 23, 2025
It was a doctor new to me so I expected a little wait for the appointment. It won' be a problem next time.
July 22, 2025
Dr. Collier is wonderful. I totally trust her and admire her professionalism with kindness and caring. She is efficient without giving the impression of being rushed.
July 22, 2025
Excellent experience at the La Mirada PIH Dermatology office: front desk staff were super-friendly and there was little wait time. Dr Collier was amazing at listening to my concerns about a new spot on my forearm, skin-checking my back for any additional spots, and recommending and prescribing a product for my keratosis pilaris. I'm glad to have her as my new dermatologist and look forward to visiting again in six months for a follow-up check on the spot on my forearm.
July 22, 2025
Dr. Collier was running a bit behind, however, she was extremely apologetic for the delay and saw me as soon as she could and was able to address all my issues. The office staff was professional and nice; they let me know about the delay as I had checked in and even offered water to all the patients while we were waiting.
July 21, 2025
It is always a pleasure to see Dr. Collier. I actually look forward to each visit because everyone is so pleasant.
July 21, 2025
Very friendly and professional
July 10, 2025
Dr. Collier is very helpful.
July 02, 2025
The experience with Dr. Avanta Collier was very, very pleasant. I wanted to put all fours, but I made a mistake and pressed one on accident. So they're all fours for her. Thank you. Bye-bye.
July 01, 2025
I saw this provider a year ago for hair loss. She told me to try topical minoxidil first. So I did and it did not work well for me. During my most recent visit, I ask her for the prescription and was told that she did not want to give it to me since I was on Spironolactone (50mg) and didn't want to give me something that would lower my blood pressure. However, she said that if my PCP was ok with it, the. She'd be ok with my PCP writing a prescription for me. I asked my PCP and she said she only prescribes minoxidil for hypertension. So I wasted $50 for the visit since she didn't do what I requested. I will not return to see this provider.
June 30, 2025
Not enough time to explain and all staffs are not nice
June 25, 2025
Unfortunately I had to wait 12 months for this appt Was a. Update on precancerous condition in the right side of my face Dr took a biopsy- I am scheduled back in September for recheck & more options Dr Collier is helpful $ explains procedures
June 24, 2025
Great staff, awesome doctor. Very professional, thorough examination, very friendly atmosphere, always a positive experience.
June 24, 2025
The office staff and doctor are wonderful.
June 17, 2025
Very knowledgeable and helpful
June 16, 2025
I thought my appt was at 1.:15 and it was at 11.15. They had no problem squeezing me in at 1.15! (PHI removed)
June 11, 2025
I received the upmost care that one might experience!
June 11, 2025
I had to wait about 5 months for an appointment
June 10, 2025
Yes, Dr. Collier is a very good doctor. I appreciate her professionalism and her knowledge.
June 02, 2025
My only concern was my follow up scheduled for January 2025 was rescheduled for a different day and time without calling me and then rescheduled to June 2025. Not the fault of the dr
June 02, 2025
I didn't feel comfortable. Office girls were discussing me as a third person as to why I was there. I interjected and they brushed me aside. My doctor wanted a biopsy done and the doctor said they don't do it there. What a waste of my time. Usually p I h is very professional.
May 27, 2025
Yeah, I was told I would be at an appointment in two months follow-up. Then I find out that I get a six-month follow-up appointment. And the doctor told me I would have a two-month appointment. And that wasn't true. I'm a little upset with that. Thank you.
May 27, 2025
Staff was friendly and courteous, both office and medical. Dr. Collier was great.
May 21, 2025
For the first question, I would have picked four, but I jumped at that and pressed two instead. (name removed), the receptionist up front, was extremely great and kind. She helped me get an appointment the same day given a very urgent skin matter, and she helped me see Dr. Collier, who I had seen previously. So, (name removed) was phenomenal, and she offered me great customer service and samples when I was checking in the lobby. Dr. Collier was nothing but exceptional. She really listened to what I had to say, answered my questions thoroughly, and provided clear instructions and great bedside manner for giving me the treatment plan, the directions. So, I'm only a few days in, and the medication that she gave me is already healing my skin. Nothing has worked.
May 21, 2025
My provider, Doctor, she was wonderful. A wonderful doctor. Thank you.
May 21, 2025
Staff are pleasant and made me comfortable
May 14, 2025
Dr. Collier was very easy to talk with. I felt very comfortable with her. She seemed knowledgeable and caring.
May 14, 2025
Dr Collier is very sweet and kind.
May 13, 2025
Dr. Collier and the staff are very friendly while working diligently and getting me taken care of in a timely manner.
May 12, 2025
I liked the doctor herself. She was great. I did not like the staff. I did not like their aftercare. They delayed my prescriptions. They didn't give me an after visit summary. They just sent me home with a new appointment, which was even unclear what the appointment was for a follow up appointment. I mean, the staff and the office and how it was run was just. Not ideal. I didn't care for that. I struggled with them, but I did think the doctor herself was fine. It's just her staff and how they follow through with the patients. That was not.
May 12, 2025
Doctor was very patient in listening to my concerns and answering my questions.
May 06, 2025
Dr. Collier is a very warm and caring physician. It was my first time with her and I trust her completely.
May 05, 2025
Great Doctor extremely patient. Rate 5 Stars
May 05, 2025
She was great.
April 29, 2025
Dr. Collier is one of my favorite doctors. She is always so kind and carefully listens to anything that might be of concern. If a treatment of some kind is needed, she is very thorough in explaining, in understandable terms, what needs to be done.
April 28, 2025
Dr Collier's office always nice and efficient. Dr. Collier always calming and listens to my concerns. Great experience.
April 22, 2025
Dr. Collier is very friendly and professional. She explains everything clearly and thoroughly.
April 21, 2025
Very courteous and caring. Dr. Collier perform a small biopsy on my left thigh and she and the nurse were very professional in their procedures.
April 15, 2025
Excellent
April 14, 2025
My visits with Dr Collier, including yesterday's visit, have been very helpful. I appreciated the fact that she took the time to perform a full-body check to make sure there was nothing abnormal. She was also friendly and respected what I had to say.
April 14, 2025
Dr. Collier, MD, was very helpful and informative. I really appreciate her taking the time to answer all my questions pertaining to my visit.
April 09, 2025
I think it needs more improvement in the fact of being more compassionate with the patient. Patients have been waiting for so long to see for an appointment and just to get the appointment it took a while. I understand that there's only limited doctors for dermatology, but even once you do get to see them, them spending the time with the explaining of what they think it is and what is it for, what other things you can do. I was in pain, burning, itchiness, and definitely not knowing the unknown of what it could be. I think a little bit more compassion with your patients will be very important as well as the staff. You know, the staff, supposedly they were going to explain to me how to take care of this or even I had a reminder for that. So just pretty much that. Thank you.
April 08, 2025
Staff and doctor were very friendly caring. We joked around. We were not rushed. Awesome people
April 01, 2025
Great doctor !!!!!
April 01, 2025
Very satisfied
March 31, 2025
Dr. Collier, is very attentive to my needs and concerns.
March 31, 2025
I took off work for this appointment, it took me 10 mins to get to the appointment was seen by the doctor and left stopped at McDonald's for food and clocked back in at work it took an hour to do all this. The doctor did not fully examine me or really look at the moles I was asking about. Was not confident on this visit at all. She didn't give me a chance to ask questions she rushed me out of the office to schedule me for another visit. It was a (word removed) joke.
March 26, 2025
Dr. Collier is great.
March 26, 2025
Good experience with Dr.Collier. She is knowledgeable and friendly. The receptionist on the other hand, when I checked in seemed bothered and had a little attitude.
March 25, 2025
Your prompts really stink. You should have one as yes and the others as somewhat no, because I inadvertently pressed one, assuming you guys had enough sense to make number one a yes. So my first answer should have been a yes or a number one.
March 19, 2025
all was good thank you
March 17, 2025
The physician that worked on me at the dermatologist clinic or hospital, she was very attentive to my needs and she listened to my concerns and she was able to take care of the issue I had. So I'm very pleased with my recent services received from Dr. (name removed). Thank you.
March 17, 2025
Office staff (everyone) very pleasant. I couldn't have asked for a better experience!! Dr. Collier was very professional and I felt heard.
March 10, 2025
I'm not too familiar with dermatology exams, so I'm not 100% sure if she was thorough.........I hear they should use a special light. Overall it was a good appointment.
March 05, 2025
Hi, the doctor was very, very instrumental in getting my mom's prescription filled. And when we thought that the insurance may decline, we received the ointment within three business days. So that was very appreciative. As my mother has lived with vitiligo for a long time, and so it was the options that the doctor gave us were also great. And we appreciate the time that she spent with us, the samples that we were given, and the staff, the staff was awesome. Thank you.
March 05, 2025
The waiting room was empty, no phones were ringing... and the gal at the front desk couldn't be bothered by looking at me, acknowledging me or even listening to my answers to her questions (she asked my name twice within the span of 60 seconds.) I felt invisible. The gal that took me to the exam room also didn't bother looking at me, acknowledging me, or listening to my answers to her questions (I said I was there for the doctor to look at some spots on my face...to which she replied "do you need to get undressed?" Ummm. Undressed? For my face? So the office staff left a lot to be desired, the doctor did answer my questions and I felt that really was the point of the visit. Aside from the fact it took 4 MONTHS to get in to see her. You guys can do better.
March 04, 2025
I have been fortunate to have Dr. Collier as my dermatologist for many years. She is always very thorough and respectful. Yesterday she had a student she was training on his rotation. Both her nurse and the doctor asked me if it was alright for the student to watch and learn. Again, very respectful of my feelings.
March 04, 2025
Doctor Collier answered all my questions and demonstrated care and professionalism regarding the procedure that took place. The medical assistant, (name removed), was very professional and provided detailed information about the after-care steps necessary for proper healing. Thank you. (PHI removed)
March 04, 2025
It is so hard to get a timely appointment in this office. Appointments are 4-6 months out and that is a big problem if you are worried about something. Now one of their MD's has left which makes it even more difficult. The MD's are always really good docs and nice. But almost impossible to get in when you need to. That's the #1 problem with PIH.
February 25, 2025
It took three months to get an appointment. Four days before my appointment I got a call changing my appointment from the morning to the afternoon. The day before my appointment I got a text showing that I had one appointment in the morning and one in the afternoon. I tried calling the office and never got a call back and was on hold for ten minutes. I just gave up and went to the afternoon appointment.
February 24, 2025
Nice doctor I do miss having (name removed). But I understand she's no longer with PIH
