I highly recommend this practice and Dr Geist who did my procedure today. He's an excellent doctor. I went for my first colonoscopy at 61 and from beginning to end was very impressed with the entire staff here. I got in right away and the procedure was done much sooner than expected due to how well this facility is run. Everyone was professional, knowledgeable, friendly and reassuring. Throughout the entire process they explain what's happening and check with you to make sure you're good. I won't need to go back for 10 years, but when I do this is where I'll go. Thanks!

Dr. Mazanec is one of those doctor you dont too often. He doesn't give up on you. Ive seen him for many years and he found cancer in my colon . Its a very long story. He just not give up when he knows hes right. And proven to be right. I wouldn't trust anyone else for this care.

The whole staff at GEC did an amazing job, from registration to wheeling me out the door. Dr Saha was very kind, professional and explained the procedure and results well. Highly recommend them!

From the moment that I got to the endoscopy center, I was met with friendly faces and lots of smiles. The young ladies that assisted with setting up my IV and getting me comfortable before my procedure were absolutely the best. The facility is super clean, tastefully decorated And easy to get in and out of. From the time I walked in until the time I was being prepped for my procedure was less Than eight minutes. I was checked on very often And made aware of everything that was about to happen. Dr. Saha Was my physician on a prior procedure and I was happy to see her For this one. I highly recommend gastroenterology associates and the endoscopy center.

The doctor i saw was very knowledgeable and easy to talk to. He had looked over my chart before coming in the room, I appreciated that. Also he didn't seem to be rushing to get out rhe door- like some who ask you "anything else " with their hand on the door knob. The staff was awesome too.

I had a very pleasant experience at Gastroenterology Associates - Augusta Road. The staff was professional, welcoming, and attentive from start to finish.

Jennifer Garren was especially knowledgeable about the colonoscopy procedure and provided clear, practical information that addressed my personal concerns about the preparation process. She took the time to explain the importance of maintaining regular bowel movements and made sure I understood why it matters for overall health.

Most importantly, they eased my anxiety by thoroughly answering all of my questions and ensuring I felt informed and comfortable. I truly appreciate the care I received and would highly recommend this practice to anyone seeking compassionate and professional gastrointestinal care.

I had an excellent experience at this GI office for my endoscopy. From the moment I walked in, the staff was welcoming, professional, and incredibly efficient. Check-in was smooth, and the nurses took the time to explain everything clearly, which immediately put me at ease.

The physician was outstanding—thorough, calm, and happy to answer all of my questions without making me feel rushed. The procedure itself went seamlessly, and I truly felt I was in capable, experienced hands the entire time.

Medical procedures can be stressful, but this team made it as comfortable and reassuring as possible. I’m very grateful for their care and would absolutely recommend this office to anyone needing GI services.

The new facility is top notch and the staff are all welcoming and caring. Dr. Palma is thorough, diligent at his research and diagnosis, and explains things in terms that are understandable. This helps ease stress and worry to patients like myself.
