"There is not a lot of face-to-face interaction between patient and physician for a colonoscopy, but what you get with John Frese rates 5-stars. He has the kind of presence that inspires confidence. His medical support staff and facilities are top-notch. HIs front office admin staff were super helpful when my prescription needed to be changed. Great practice overall."

"Colonoscopy..ugh...CoastalGI makes the ending (no pun) MUCH more pleasant than the prep!. Check-in is simple, wait timeat your appointed time is minimal, incoming prep nursing friendly/efficient (Laurie), anesthesiologist direct and friendly, Doc Frese friendly (for the few seconds before the happy juice takes effect) and efficient, and the discharge nurse was friendly/efficient/understanding..(Lisa). Highly recommend this practice...you'll be thankful "in the end" for choosing this practice!"

"Dr. Frese and all of the staff that I have encountered at Connecticut GI/Coastal Digestive Diseases have been excellent. I have been there for three screening procedures over the last 10 years or so and no issues at all. The staff are always friendly and caring and have always followed up to make sure I am doing OK the next day."

"This was my 4th or 5th colonoscopy performed by Dr. Frese, and as with all the previous procedures, he and his staff were excellent. He always greets you before the anesthesia for any question you might have, sees you in recovery and calls a couple days after the procedure to go over results if polyps were removed. The staff at the facility are also all professional, friendly, respectful and helpful throughout the preparation and day of the procedure."

"Just wish he would tell me what's wrong with me instead of saying nothing. He also, tells you he will get back to you and does not. His staff is not always on top of things."
