FYI, to the person up above that is upset about the out of network, my insurance helps me get ride of the bill. and the hospitals fail to show the fine print that we sign stating certain medical people are not in the network, so do a review on the hospital , not the Doctor!! The same thing has happened to me numerous times at different hospitals. It is not the Doctors fault, it is who the hospitals chose, Dr. V is an awesome Doctor

BEWARE: This doctor used OUT OF NETWORK anesthesia during my surgery which cost me $1500 over my in network copays. I'll never let him or Clear Lake Surgery Center touch me again!

I highly recommend Dr. V. He and his staff are very kind and compassionate. During one visit when I was having a rough time Ashley (his PA) gave me her undivided attention for a long time to answer all of my questions. Another day Monica called me back to the exam room with a bubbly introduction. Marie called me one day to see how I was doing. Dr. V took a vacation and kept asking his staff how I was doing while on vacation. And Dr. V is very conservative in his treatment approach.

Dr. Voloyiannis and his team provided excellent care for my husband during a recent surgery. He explained the surgical process in a way that was easy to understand...even drew pictures. Surgery was scheduled quickly. This meant the office remained open briefly to make sure everything was complete. All this with a wonderful attitude. A very caring dr and staff as well!

Dr. Voloyiannis helped me with some difficult surgeries involving my colon. He has great bedside manner and is able to easily explain options. The only issue I had was he promised he would see my case to the end and then left the hospital where my insurance was covered. He was passionate about helping me at the new hospital, but my insurance did not allow it. Unfortunately, he neglected to tell me his privileges at the prior hospital were suspended as I had to find this out through other means.

Dr. V removed 8” of my colon on a Monday. I was home on Wednesday. I feel like I was granted a miracle, given through Dr. V’s hands. Two weeks out of surgery and I am doing exceptionally well! He is my hero.

Dr. v and Ashley saved my life I was admitted in the hospital 07/30/2016 with a small tear in my colon which resulted in a perforated manner . I had major surgery with him to fix my perforted colon and then was given a temporary colostomy bag . Dr. V and Ashley kept me informed of what to exspect and how things were to go . Needless to say everything went really well had my reversal 01/25 with no problems I'm feeling great and excited to continue my journey . I love them and will recommend them.

Great surgeon, did a fistula removal and bowel resection. With the surgery done laparoscopy my time in the hospital was 5 days. He listens and cares about his patients. His nurse is also wonderful and very organized. If you need colon or rectal surgery this is the surgeon for the job.

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!!
