Dr Peter Chansky and staff are very kind, clear and effective providers. I look forward to my appointments and have been very happy with my results.
Verified Branded Directory patient
The diagnosis itself was accurate, but the overall experience was deeply disappointing. The physician’s bedside manner was dismissive and condescending; I felt spoken to as though I were an inconvenience rather than a patient, bordering on patronizing. The visit was rushed—lasting around eight to ten minutes—and concluded abruptly, with him exiting walking out during his final remark. In all my years working within the medical field, I have never encountered such an interaction. Even among colleagues known for being brusque, I have not seen a patient treated in this way. The MA appeared to recognize the situation, offering a quiet apology and explaining they need to keep the schedule moving It seemed my attempt to address multiple concerns may have been perceived as burdensome. While I am grateful that at least one issue was diagnosed and a prescription provided, the efficiency felt less like attentiveness and more like being hurried out with little regard for patient care or respect.
Everything was great

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!
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!
Great visit, thanks Dr. Chansky!

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.
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.
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!
