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.

The doctor's office is professional all of the staff were professional, and efficient, and courteous, and people were respecting The Mask policy. And the offices were clean. The wait was minimal and I thought that the doctor was efficient. She was thorough And then You know, offered a treatment right there for one issue and then he gave me very clear instructions about it and scheduled another visit a follow up. So yeah, so overall I definitely recommend this office and the doctor thank you.

May 13, 2021
I appreciate that Dr. Collier was ready for our virtual appt exactly at our scheduled time. She was responsive to my email after our appt and was attentive during our visit.
May 12, 2021
When I was all done and came out to see a receptionist to schedule my next appointment, no one was around. I waited about 5min, then yelled over to a woman sitting in an office there, near by. She with her back turned, answered, yes, may I help you? I said yes I need to schedule my follow up appointment and there's not anyone around. She said in how long? 2 mos or 3mos? I said 3. She asked me my birthdate and what time I'd like the appointment at, all with her back still turned and sitting in that office. Once she scheduled the appointment, then she printed a copy for me to take, then got up and handed it to me. Thought this was somewhat rude. Usually the person gets up to help you. Maybe she was bothered by having to make the appointment for me. Very unprofessional.
May 12, 2021

March 08, 2021
The customer service when I came to the office was very rude. The lady was on a personal phone call and didn't help me at all and was very rude to me.
March 08, 2021
Dr Collier is a great Dermatologist and she is very thorough. Answered all my questions and addressed all my concerns. Scheduling a next appointment is a bit awkward. Must be an out dated computer scheduling program. We have to call in at a later date to make a next appointment.

Dr. Collier and the staff feel like they are my friend's. They are professional but also make you feel at ease. I can tell that they truly care about patients.
February 25, 2021
Our consultation was less than 10 minutes. She did not explain or seemed to care for what I had to say. I was prescribed something without even knowing what my skin condition might be and didn't have a chance to even ask questions. Worst service. Rushed and not acknowledged. It felt like a quick transaction. Zero humanity for my concerns.
February 23, 2021
I received a text asking me to confirm my appointment, I checked in on-line and I received another text reminding me of my appointment. My appointment was at 2:00 pm and did not see the Dr. until 2:45. I left work early for my appointment so a text letting me know that they were behind schedule would have been nice.
February 23, 2021
Long wait, and the appt felt very rushed.
February 22, 2021
She was patient, kind and expressed concern about the reason why I was there. She fully explained everything in a manner I could understand. I would definitely recommend her as a Dermatologist.
February 22, 2021
Dr. Collier and her staff were great as always
February 16, 2021
Alright, it's three things that you need to improve on his one. The individual female that takes the appointment times has an attitude like you're bothering her and her attitude needs to be change in the more positive manner because it all means made me hang up. I've had to deal with her 3 times to it'd be really good if the doctor when they're prescribing medicine to you, make sure first of all your insurance company will cover it and it is an affordable price. Whenever referring you to a doctor because they don't handle that particular thing. It would be really great. If the person they're referring you too isn't in a distance. For example, I don't really care to go to Torrance to go see the specialist doctor that they referred me too. So, I think they need to give us more options instead of just the one person who deals with thing. So outside of that doctor is always fabulous. She's very attentive and she gets things done.

Actually, I'm pretty disappointed that every time I tried to make an appointment to see any dermatologist, I had to wait about two months. That's unacceptable.
