Make an Appointment


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.

What a GEM of a human you have in Dr. Collier. She is kind, sweet and professional at every single visit. She is uplifting, gentle and diligent in her work while she speaks to you with care and kindness. It's not always an easy topic when you are dealing with worts and concerning moles and she somehow made it pleasant and enjoyable! I was having a rough week and I genuinely felt better leaving her office even after getting cut, burned and frozen! Her nurse was great as well. She is truly remarkable at what she does.
September 14, 2022
Dr. Collier is extremely knowledgeable, respectful and thorough.
September 13, 2022

Dr. Collier is THE BEST!
August 08, 2022
Dr. Collier is very friendly. She's just a joy to work with. She answers all questions, expediently. And you get to know on a one to one basis. I know she has a little girl and employee and we talked about her and it was my asking not her telling me about a little girl. The staff is great, the office is just very pleasant and Dr. Collier couldn't be a better doctor, I was in the medical field all my life and she's great.Thank you.

I have been seeing Dr. Collier for some time now and find her to always be very warm and compassionate. She always listens carefully to my concerns and addresses any skin issues in a timely manner. Dr. Collier is one of my favorite doctors to visit.
August 01, 2022
Dr. Collier is caring, understanding and very professional.
July 25, 2022
After not being able to get an appointment for several months ( appointment I had since early July in October 2022) my Doctor was able to have this Doctor give me a video appointment. And this Doctor thank God God is going to see me sooner in her office.
July 25, 2022
Dr. Collier is very relatable and kind besides being a great doctor.
July 20, 2022
Took many calls of waiting over 20 minutes each and then disconnecting and then when finally speaking with a person I had a 2 month wait to get an appointment to see the doctor for a suspicious spot on my arm which the doctor now says may need to be biopsied. When checking in at the front desk, the receptionist did not understand my insurance which is a Medicare Advantage plan (printed on my insurance card as such) and insisted I give her my medicare card which I was told by my insurance to never carry. She then ridiculously questioned whether I even have Medicare (which I have had for and paid for for 2-1/2 years) which caused me unnecessary stress as if I wasn't going to be able to see the doctor. Then once she actually entered my insurance card, all was miraculously fine. Felt awful from that experience. Dr. Collier is a wonderful doctor. She is patient, listens to my concerns and took great care in tending to my needs.
July 13, 2022
earliest appointment was two months out. And the software for appointments can't go out 12 months. Seems like that'd be rule, not an exception. Most people see their doctors once a year. So now I have to call back in 2 months to set up the appointment for next year.
July 13, 2022
Very nice doctor.
July 06, 2022

June 27, 2022
This provider spent about 30 seconds, looking at my back, 30 seconds, looking at my arm and I was expecting a full body analysis. I had shave my body prepared. I had a lot of little gross and (INAUDIBLE) and spent (INAUDIBLE) examining my skin. Would not recommend this provider.

May 18, 2022
I've had other PIH appointments recently and this is by far the one that I didn't mind at all. Dr. Collier made me feel at ease. She was very patient with my questions and concerns. I didn't have to wait for months, that was refreshing and calming in itself. Good first visit!
May 18, 2022

April 20, 2022
Dr. Collier, the medical team and the office are professional, personable and responsive. I've recommended PIH and Dr. Collier to my wife, my brother and friends.
April 20, 2022
The office staff was extremely friendly and knowledgeable, and Dr. Collier was very helpful to me, and very knowledgeable. And I respect her greatly.
April 19, 2022
The office staff was nice. To let me go back but I waited at least 30 minutes or more in a very small room. I was getting claustrophobic and every time I. Open the door, the girl would say she had to close it. Finally, I told her I'm just going to leave. And she said, well, she'll be here in a minute there. Down there making notes. finally, they came in, but It was very uncomfortable at the end. Okay, that's it. Bye. Bye.
April 18, 2022
Yes, I was not able to schedule my appointment for past January. I had to wait until September to call and to do the scheduling. So that would have been nice if I got a reminder in doing that on rather than having to remind myself, but it was excellent and everything was great and I appreciate it. Thanks so much.
April 18, 2022
Dr. Collier has a Great bedside manner! Getting an appointment was the issue. Had to book 2 1/2 - 3 months in advance to see her. The other Dermatologist were all booked the same. Very difficult.
April 13, 2022
This is my second visit to Dr. Collier and I'm very pleased with her. She's very kind efficient and friendly, I feel very at ease with her and really a great experience.
April 13, 2022
Not enough experience with this provider to recommend.
April 12, 2022
I appreciate that to call your skill, and competence and your kindness. I feel that I owe my... I'm cancer free now because of her. I appreciate it very much.
April 06, 2022
Dr Collier is amazing. She listened to my concerns and addressed each one. The scheduling staff was great too. Only downfall is that I had to wait 3-4 months for the 1st appointment
April 04, 2022
It has always been difficult to schedule appointments with any of the various PIH providers as there are no late afternoon or even evening slots available. This makes it very difficult to plan around work.
March 28, 2022
I really appreciate Dr. Collier. She's professional. She's kind. She cares. She always asks me how I'm doing. I feel very comfortable to discuss my issues.
March 22, 2022
I may have answered one of those incorrectly. The ... the Dr was very, very kind, and wonderful, and she was timely, but I was not able to make the appointment very quickly. I actually went back to my regular Dr again before I could actually see her (INAUDIBLE). So that's (INAUDIBLE), but other than that, everything went well, I just don't think my insurance covers everything. So, thank you very much.
March 16, 2022
My provider was relocated from Whittier to La Miranda. It was inconvenient for me traveling to appointment. I am hoping she will be located backe to Whittier. I drive from San Dimas.
March 16, 2022

February 28, 2022
I just felt she wasn't very thorough with checking my skin and I had to point things out. Will probably be looking for different doctor.
February 24, 2022
The doctor was very friendly and helpful. She listened to my concerns and came up with a treatment plan for me.
February 23, 2022
Thank you to all for being there to assist.
February 17, 2022
Dr. Collier made it so easy for us to talk to her, to show our concerns to her, and to try to help us find the best solution for my daughter severe eczema.
February 16, 2022
They could possibly work on scheduling an appointment sooner. I had to wait approximately maybe 3 months or more to be seen by a dermatologist. That's probably the only thing that I could say was possibly negative. But overall, once I did attend the appointment, it was a great experience. But just to get an appointment, I had to wait several months.
February 16, 2022
I'm sorry, I inadvertently, press one for know on the previous question, which I believe was what I recommend them to my family and friends and I definitely would everything went very smoothly there and I appreciate it. Their help. Thank you.

February 08, 2022
Ms. Collier is great.
February 08, 2022
Everything was wonderful, I felt welcomed & the reception at the desk was very kind and helpful. Dr. Collier was great. I only met Dr. Collier once and She made me feel comfortable and at ease...hopefully she will be handling my procedure. Thank you. ?
January 31, 2022
Hello, I had a wonderful experience at the doctor's office. There were just a few buttons, I accidentally pressed. But there's 4's across the board all the way, accidentally, press one, but I meant for it to be a 4 and then I accidentally pressed everything meant to be a 10. So I had no.
January 31, 2022
Very nice doctor, seemed concerned with my care and took the steps to make sure everything was OK. I appreciated her care.
January 26, 2022
Dr Collier was professional and kind. she went above and beyond to help me
January 26, 2022
We did not need this physician urgently, but when you need a Primary, Cardiologist, Urologist, or Pulmonologist, a patient CANNOT get an appointment in a timely manner. Even if the hospital upon your release tells you that you need to see a doctor from one of these departments within 1 to 2 weeks, you first have to get into the Primary's office for a referral (2 weeks), then wait for the referral to go through and THEN try to get the Specialist appointment (4 MORE weeks). This is dangerous and unacceptable.
January 26, 2022
I think she's great and I have already recommend her for two different people and one's already got an appointment and I'm waiting for the other girl to come down and she's going to make appointment. I think that she's just the best. Okay.
January 26, 2022
Dr. Collier spent time listening to my concerns and answered all my questions. She was respectful and took my input into my care. She gave me options along with recommendations rather than dictating what I was required to do.she has great rapport with patients and her competence was clear in her explanations.
January 19, 2022
It took a long time to get an appointment with the Dr. But I assume that is because she is busy. I hope we get my concerns figured out. We have just started the process.
January 18, 2022
Dr. Collier is a real gem. The front and back office staff were very nice
January 17, 2022
(INAUDIBLE). Thank you.
January 04, 2022
Dr. Collier is very kind and compassionate. She takes the time to explain what she is doing and listens to and answers questions that I have had.
December 27, 2021
Dr. Collier was incredibly patient and was very thorough in not only explaining everything but making me feel comfortable. To be frank, I was a little afraid about the procedure that I had to do and she made me feel like it was okay. And for that, I appreciate it immensely.
December 22, 2021
It was a good experience. This is my second visit at the Dermatology office. The second visit was very... I liked it. I liked the attention compared to other times. So yes, I am very satisfied. Thank you.
December 21, 2021
Dr Collier is very professional, very knowledgeable, nice and caring. This appointment was my first with her I will definitely return to see her.

She has a great "bedside manner", very special person!!
December 08, 2021
The doctor is so awesome.. we need more doctors like her ..
December 08, 2021
The only disappointment is the prescription was not sent ton pharmacy until her end of day. I don't usually have to wait so long with other doctors. It would have been nice if she had let me know so I didn't have to bother the pharmacy.
December 06, 2021
I have been with PIH Health physicians for over 20 years. I have decided that I am finally moving my entire family out of PIH and finding a different hospital and providers. PIH can no longer accommodate appointments within a timely manner and their billing is terrible. For any type of procedure I have at this hospital I pay thousands versus if I have it somewhere else I pay maybe $100. It takes months to get into any of PIH providers and if they can't accommodate you with an appointment everyone's answer is go to urgent care. I've had it with PIH and I will be moving my family somewhere else.
December 01, 2021
Very professional and put me at ease.
November 30, 2021
Dr.Collier is very kind and understanding. I purposely waited to have an appointment with her.

Pleasant and efficient visit
November 16, 2021
It was incredible what the secretary did to get me in, to the office there. And everybody was so polite about everything. And as soon as there was an opening she called me. So I could go in to see the doctor, which I needed to do. So yes, excellent...excellent. And just was fantastic, but I could get in when I did. And get taken care of. They were all excellent people with it, too, and I appreciate it that. Thank you.
November 15, 2021

November 02, 2021
Yes, she is a wonderful doctor. We've gone to her her for a long time.We would recommend her to anyone in fact we do already, she is great as easy to get to her place rather than the wells building. It's not a zoo. It's pretty quiet and beautiful. Nice location. Yes, we would recommend her, and our office. Thank you very much. Bye. Bye.
November 01, 2021
The doctor was very attentive and very professional in her diagnosis.
November 01, 2021
My time with Dr. Collier was wonderful. [PHI removed]
October 19, 2021
Dr. Collier made my child feel safe and calm during an uncomfortable procedure and I am so happy we found her!
October 19, 2021
Dr. Collier and her office staff were very pleasant and listened to my concerns and needs.
October 13, 2021
Dr. Collier is both professional and very personable, and I feel very secure taking my child. She listened, and she explained, and she is very helpful during their time of concern. I did feel though that the nurse whoever walked us in and walked us out was in a hurry and just just, you know, when I spoke didn't even look at me in the eye was like come on let's hurry up let's let's leave already come on come on let's go let's go. So, I was quite disappointed because of all the years and even though it shows my son is being a first time here but hadn't been there 3 years we've seen, Dr. Collier and never once have felt like this, but it was up representative that just wanted to hurry up and get us in and get out for the most part. So I was out there last. I just felt very
October 12, 2021
The biggest problem with my experience to Dr. Collier's office is the supervisor did not wear a mask and she walked around and got in everybody's face and sat right over the other people working and looked in their computer screen and she had no respect for the mask mandate. That was really a horrible thing. That's all.
October 11, 2021
Trying to make an appt when you have an issue is impossible. With my original Dr there were no appts until next year but they could squeeze me in to see another Dr, who was very good, but I had to wait 2 weeks which the Dr apologized for.
October 06, 2021
She is a wonderful doctor!
