Painless colonoscopy. Very thorough.
Venice, FL |
My mom went to him in June referred by primary care physician. She's over 50 and primary had been on her to get colonoscopy since she'd never had one. It was discussed at first visit that she was there for routine only like mammogram. Demasi charged her almost 2k! She has other problems that her primary already figured out and diagnosed. My father had just passed away -routine is affordable. Insurance, primary, everyone was upset. He refused to recode as routine. We could lose all now.

I have been a patient of Dr. DeMasi for many years... No matter how bad you're feeling he always has a way to make you smile... His staff is top notch! I couldn't ask for a better group of professionals to take care of my medical needs...

A very pleasant & calm Gentleman with a great sense of humor. His "bedside manner" is commendable and most welcomed in his area of Medicine. His Staff members are Professional and Personable. His Suite is calm and tastefully decorated. A clean and comfortable environment is greatly appreciated!

I have been a patient since 2000 when DR. R De Masi and dad visited me at Venice Hospital. After I had been in hospital three days they immediately diagnosed C Diff and prescribed medication. After five more days I was released and began recovery. I have been a very satisfied De Masi Digestive patient since then, receiving testing such as colonoscopy and endoscopy. Ken Perkins

Dr Demasi did a great job fixing all my concerns with one visit. And his staff went far and beyond to ease my stress level. Its all good
in Port Charlotte, FL |
I found the office to be adequately staffed, friendly, and attentive. Also, I was seen promptly, and Dr. DeMasi was very professional and answered all of my questions. I had an extremely good experience, and I highly recommend them!
in North Port, FL |
He is the best in our area! After three years of suffering with UC, many hospitalizations, blood transfusions and steroids I really though I'd die. After 2 weeks in his care I've been in total remission for 4 years. Before him my other specialist did nothing to help me. He knows his stuff and if he didn't he would go the extra mile to find someone who did. Not you're typical Dr. He really cares. I'm am very lucky and grateful to have him as my doctor.
