Patient Comments (3)
Dr John Siebert is a confessed and convicted. he has been convicted as "morally-unfit" in NY State by the NY State Department of Health. He has been FIRED by 5 NYC Hospitals after his being convicted and suspended. UW Hospital is the only Hospital in the World who will allow Siebert Medical Access to Patients. WHY? Because Siebert has a Hold on Pres of UW Ronn Slwinski. Siebert is a confessed MORALLY UNFIT, a perjurer and a thief. he has robbed a fortune

I needed Dr. Siebert to fix the first reconstruction surgery from another Doctor. Truly was so upset that I wanted the implants out. he and his MA Luann took the time to go over all the options with me their was no hurry in my appointment at all. just had the surgery a week ago and I even gave the doctor and out before the surgery that if he could not fix the mistake by the other doctor and make them look human he could take them out. He said okay but would not need to. He was right!!

5 stars are really not enough for Dr. Siebert and his staff. Dr. Siebert is the GO TO SURGEON for for anything breast related. I recently had a breast reduction and I couldn't be happier with the results and the excellent pre & post op care. Dr. Siebert is # 1an excellent surgeon, for me, anything after that is BONUS. Luckily, he is also respectful, highly professional, warm, and funny. He and his staff really put me at ease and I had the utmost confidence I was in the best care possible. THANKS
