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!

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.
