I have total confidence in Dr. V. and his surgical expertise. He is extremely reassuring and comforting, so very pleasant to speak with, and willing to respectfully answer any questions I have, which is appreciated from a surgeon. (Ashley, his PA is also fantastic.) I am grateful for his careful decisions made and for all he has done for me to treat my condition.

Dr. V is one of the most kind and compassionate doctors I have ever been to. He is and expert in his field but takes the time with each patient. He is a rarity in the medical field with brilliance in his field but compassion for humanity and extreme courtesy.

I owe my life to Dr. Voloyiannis he saved my life 2 in the past 2 years. Two days before my 40th birthday I ended up in the ER at SE Memorial & lil did I know that was about to be told that I had Stage IV Colon Cancer I was in tears and so scarred but once I met him I knew I was in good hands. I thank God every day for putting him in my path. He is a loving, caring Dr. he takes the time to listen to you he treats you like family not just a patient. I am eternally grateful to him. There are no words to express how grateful I am to him. I really recommend him. His Assistant is also very kind she makes u feel very comfortable as well what can I say his entire staff is Awesome.

He is so caring and thorough - He saved my 91 year old Mother's life when he found colon cancer when she had been admitted to the hospital for a fall. Our entire family fell in love with his attentiveness to her and her problems. We are all scheduling our colonoscopy with him soon.
