I am a Vascular Surgeon and had hair transplantation by Dr Chumak last January. First and foremost he was the most honest in what could be done and what results to expect. Now, 10 months later, I have no visible donor site change and a full head of hair that is remarkable. Lastly, Dr Chumak’s staff is second to none, kind, professional with prompt responses to any question. Again, I know what a great doctor and office is, having had a vascular/thoracic practice in NY for over 25 years.
