Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Very caring
This office actually makes a colonoscopy a pleasant experience (except of course the prep, but that’s another story). Very personable, professional and caring staff. Dr. Baltz is a sweetheart. Loved the anesthesiologist (can’t remember his name - also a sweetheart). Nurses outstanding.

Fantastic Job
I had my first colonoscopy and was quite nervous about it. Dr. Baltz and everyone at G.I. did an incredible job. It was top notch all the way around and can recommend them enthusiastically!

Colonoscopy
All staff were friendly and helpful, listened to my concerns, and answered all my questions. I have had concerning results in the past so am multiple repeat patient. No need to look for another GI doctor or facility. Very happy.

Excellent place
I could write a book about how great GI Assoc. is and Dr. Baltz. When you check in you meet a pleasant receptionist. When you go to meet the nurses they are so nice and don’t make you feel embarrassed for what’s about to happen. They talk about other things and keep your mind off of the procedure. I actually had fun. This includes the recovery nurse as well. All 3 of them were always smiling. They all know what they’re doing and take care of you. Dr. Baltz is the best. He comes in before to tell you he’ll take of everything. He makes you feel comfortable. After he comes back in and lets you know how it went what they found and explains it all. Great doctor. I believe this is my third time and might be my fourth. I will never change because of the staff! They are awesome. Thank you all for doing what you do.

This Physician's Choice in Gastroenterologists
Excellent physician, very thorough colonoscopies, extensive understanding of the broad field of medicine, great bedside manner and very personable. I have watched him perform a few thousand colonoscopies and upper endoscopies over the last 8 years in my role as an anesthesiologist and he is superb. My first choice among the dozens of gastroenterologists I have known and worked with.
