Dr. Kalmowitz is a blessing. So grateful that I found him. He is very thorough and explains everything so clearly. He and Jen Fallon are the best!

so i went there the first time 3 years ago and became very sick after procedure non stop throwing up just awful for the next two days so this time 3 years later told them ahead of time i need something that’s going to help nausea and that i felt awful last time they said they would give me something for it yet this time i actually got more sick maybe not anyone’s fault there i must be not doing well with anesthesia but iam still upset i got so sick even after i told them … staff is very nice doc very nice but i just had an awful experience twice

Dr. Kalmowitz is a doctor who is friendly, funny, and honest. He knows his field and his patients- beyond that is kind- and compassionate. I would recommend him to anyone.

He is well regarded amongst his peers. Does my colonoscopy and did an endoscopy to “stretch” my esophagus. Foods/ liquids tend to want to not get into my stomach fast enough and without the stretch I could aspirate into my lungs and get pneumonia. He’s on top of it. 100% anesthesia. No pain. Update: I have a new combination colonoscopy and esophagus surgery on June 20 at Roger Williams Hospital dual surgery under complete anesthesia. My kind of surgery. It’s a complicated procedure as I’m on a blood thinner and we have to get clearance from my Cardiovascular surgeon first. Looking forward to getting it over with.

Very happy with the way the procedure went. Very professional in every way. I would highly recommend this place.
