“It was my first time doing a full body skin cancer scan, which the provider knew, so I would’ve appreciated being talked through as she was looking over truly every inch of my body. It felt rushed and hard to keep up with the pace of the small talk. You could also hear the provider and their patient in the next room, not clearly but still a little weird. Otherwise the entire practice was very clean and professional.”

The experience was amazing! I’m from Spain, so being able to speak with her in Spanish was a huge plus for me. She listened carefully to my whole story and all of my questions, and she recommended the best treatment option for my acne.

Dr Diaz is the best. She listened to all my issues and took it all into account. She’s super nice and really easy to talk to. Also very knowledgeable.
I always trust I’m in good hands when I see her. And she’s helped me treat issues that plagued me for long periods of time. She knows what she’s doing!

The office was incredibly clean and professional, I was seen even before my scheduled time (I arrived early) and the doctor was understanding, respectful, and thorough.

This is my second time seeing Dr. Diaz. She was knowledgeable, a good listener and a communicator and addressed all my concerns. However, as soon as I leave the office, it’s extremely hard to connect with anyone in the office via their online portal which is their recommended communication channel. I have a prescription that requires a prior authorization. I messaged them twice via Klara with no response and had my insurance contact the office directly twice as well. Both times a message was left with the front desk. I have also called them directly multiple times but was never able to speak directly with their PA team. While the overall in-office experience was decent, the unresponsiveness was frustrating especially when it’s related to an urgent matter. I would not recommend this clinic to anyone.

Got good advice prescriptions and she listened well. I wish I could have had more time to explain a few things and get a more detailed exam. I’ll go back for further details.

Great office at a great location with a great view of Central Park. Friendly staff, from receptionist to assistant to doctor. Listened to all concerns and they were all addressed very thoroughly. Everything was explained so I could go home and feel comfortable in my own skin. Highly recommended for anyone searching for a dermatologist.
August 20, 2025Michael R.Verified patient
she was okay but the experience was very rushed, felt like she was trying to do the bare minimum before she rushed out for the next appointment and did not fully explain how I should be using the products she was recommending

The appointment felt rushed. The doctor was kind, but she didn’t offer any explanations. I had to ask all the questions just to get basic information, which was frustrating

I was experiencing a lot of discomfort, and Dr Diaz provided me with answers and solutions quickly and efficiently. When I continued to feel discomfort, and stayed in communication with me while she was out of office to help me find relief and solve my problem. I really appreciated her attentiveness to my situation!
