Doctor Voloylannis and his office staff were very professional and always helpful. Doctor V. will perform my colostomy reversal in a few months and I'm confident I'm in good hands. I will definite recommend to others.

This is my second surgery to remove my hemorrhoids. My 1st surgeon is Kelly Gilmore-Lynch and she messed me up BIG time!! It took me almost a year to finally decide to go through the same procedure again. I'm so glad I found Dr. Voloyiannis! I wish I had known him before. I have suffered enough from my previous surgery. Not only did he repaired the other surgeon's mistakes, the recovery from this procedure is a lot less painful. I definitely recommend!!
