I've been Dr. Chansky's patient for quite a while now, and I continue to be impressed with the level of care he provides. He has a wonderful bedside manner—kind, patient, and truly attentive to every concern I bring up. He listens carefully and makes you feel heard and understood, never rushed. His positive attitude immediately puts you at ease, and it’s clear he genuinely cares about his patients’ well-being.
What stands out most is how he consistently goes above and beyond to find the right solution, taking the time to explain options and tailor treatment to your specific needs. I completely trust his judgment and feel confident in the care he provides. Highly recommend!
February 26, 2026Alexandra J.Verified patient
I highly recommend Dr. Chansky for all your Botox needs. His skill, precision, and aesthetic eye are truly exceptional — he delivers results that look natural, refreshed, and never overdone. I always leave looking like the best version of myself and I have not been able to find anyone else I trust with my face.
Beyond his expertise, he is warm, thoughtful, and makes every visit feel comfortable and easy. I trust him completely - to the point that I have traveled to SF specifically to see him. Five stars!

February 9, 2026Sean P.Verified patient
I had been struggling with acne for a long time, and Dr. Chansky prescribed spironolactone, which worked incredibly well for me. The improvement in my skin made a huge difference in my confidence.
Beyond the treatment itself, he is attentive, patient, and genuinely kind. He truly listens and takes the time to understand your concerns. I always felt heard and well cared for during my appointments.
January 31, 2026Kelly M.Verified patient
Dr Chansky is an excellent dermatologist. He is clear and communicative from the start to the end. In addition, the nurses are incredibly kind, patient, and polite. Would highly recommend this office to anyone looking for a top tier dermatologist.
January 20, 2026Kyle N.Verified patient
Dr. Chansky is clearly knowledgeable and the office is well run and the office staff was kind and easy to work with. However, the speed of the visit was jarring. He was answering my questions about one issue while simultaneously speed-checking my skin and the multitasking felt frantic rather than efficient. He was in and out so fast that I felt dismissed and too overwhelmed to ask anything else.

I came in for a common issue, yet Dr Chansky was rather condescending. He offered treatment options with minimum explanation, I had to ask multiple questions to get the pros and cons of each treatment. My concerns on the side effect weren't addressed with a slightly condescending expression and tone. The office staff on the other hand were great!

Wonderful Dr. Really takes time to look after you and understand whats going on. If I could say one thing, I felt very cared for. More than the basics, it was like he really cared for my well being. Great staff.
December 7, 2025Ray T.Verified patient
Great as always! The office is well-staffed and organized. Dr. Chansky is very knowledgeable, friendly, and has helped me with both immediate serious issues as well as long-term care for my eczema. I’m very glad I found this clinic and strongly recommend them!
December 3, 2025Emily Y.Verified patient
I waited 30 minutes past my scheduled appointment time and the appointment lasted 10 minutes (probably faster if I hadn’t asked follow up questions). I came in about concerning moles, hyperpigmentation, and dry skin and Dr. Chansky shared everything looked normal. While I appreciated the quick reassurance, I didn’t feel the feedback was actionable. For example, with the concerning nevus, he said it looked completely normal and didn’t offer any guidance like checking if it gets raised, removing it from the sun, or monitoring if it increases in size. I even had to ask for a pamphlet on concerning moles to get more information.
Similarly for all other concerns, he just shared things looked normal without offering guidance on how I could reduce my concerns. I didn’t feel like he listened to my concerns or offered any preventative tips.

Dr Peter was great, I was previously wrongly diagnosed with Perioral Dermatitis and he was very kind and patient when explaining about my treatment
October 7, 2025Victoria B.Verified patient
BE AWARE, you could get charged several hundreds for a very short consultation visit, like how I was. I came looking for advice on in-grown facial hair treatment, the doctor told me to purchase razorless shaving cream off amazon, then I left. This entire visit, starting from the 1st hello I made to the doctor, lasted under 5 minutes. The doctor didn't perform any involved medical examination or procedure on me during that time. The advice given was ok, I guess, but I still have ingrown hair bumps on face after using the cream, so take this story as you will.

The appointment was about 10 minutes long. It was not clear if he washed his hands prior to touching my face. He prescribed medication right away one being spiro. After I did my own research into side effects, I realized I didn’t want to go this route. It didn’t align with my wellness goals. But the visit was so rushed I feel I didn’t even had a chance to think. I was able to sneak in some questions but they also felt super rushed.

Dr. Chansky and his staff are great
September 25, 2025Ellen M.Verified patient
I recommend Dr Chansky 1000%. Not only is he a thorough, knowledgeable doctor, he is kind and a really great human being. Another note is that on many visits he has had a “shadow” resident doc. It doesn’t go unnoticed to me that not only is he a good teacher, he is also so respectful and kind to the resident. Yep, he truly is a stellar human being and a real gem.

Dr. Chansky is an exceptional dermatologist—skilled, thorough, and incredibly personable. From the moment you meet her, she makes you feel heard and genuinely cared for. She takes the time to explain diagnoses and treatment options in a clear, understandable way, never making you feel rushed. Her expertise is evident in every recommendation, and her warm, approachable manner makes appointments comfortable and stress-free. I leave every visit feeling confident in my care and grateful to have such a knowledgeable and compassionate doctor. Highly recommend!

Dr. Chansky was professional and knowledgeable and communicated really well with my 11 year old about a derm issue. He listened to her concerns and he talked to her in a way she could understand the process and outcomes. I'd highly recommend him.
