What People Say About Dr. Aaron Baltz, MD

I am a physician and I see Dr. Baltz for my digestive health. He is thorough in the office and with his communication and follow up. He explains things well. He is a talented endoscopist who I trust 100% to care for me. I refer family and friends to Dr. Baltz and GI Associates for consults and procedures. As an independent GI practice their primary focus is on the patient.

I recently had a combined Colonoscopy and EGD that ended with a sever bleed and expensive hospital stay. The slow response from GI Associates & my doctor was unacceptable. Approx 12hrs after entering the hospital a GI doc (not my doc) finally went back in and clip the bleeder (after he had already done 10 procedures that morning), I guess I was not a priority. Over 2 wks now & not a word from GI /my doc but the bills were right on time.

Forgive me if I don't remember all the names I do remember the faces. Scheduling was a breeze. The woman I talked to was great. Very pleasant. When I arrived the day of the procedure, :Lauren knew what she was doing. Told me everything that was going to happen. She knows what she's doing. The nurse in the exam room kept me talking about anything except what was going to happen. Kept my mind off everything. She was awesome! You have an excellent staff that makes an unpleasant visit, pleasant.
