Dr. Jones is an outstanding gastroenterologist. He is attentive, takes time to truly listen, and is very proactive in addressing concerns and developing a treatment plan. I never feel rushed during appointments, and he always makes sure my questions are answered. It is clear that he genuinely cares about his patients and providing excellent care. I highly recommend him.

Great facility and practice from my experience. These folks seem to care about your health and take the time to cover your questions/concerns. I was able to get an appointment fairly quickly and also able to schedule a procedure much faster than I thought.

I have been going to this practice since 1985. My Doctors were Dr. Gould, Dr. Daves and now Dr. Jones. I also have been seen by PA Allyson naylor. I even drove to Clemson when Dr Daves semi retired there until he completely retired. He handed me off to dr. Jones. This group to me is the gold standard for doctors practice. Every person that i interact with is friendly, caring, perfessional, timely and knowledgeable. Dr. Jones and his staff, nurses, technicians etc are the best in the upstate. I also really like the fact they are privately owned and not locked into any one hospital. Their facilities are clean bright and state of art. Best of the best!

Initially, I dreaded the procedure, but the prep was much easier this time. And, once I arrived, I didn't have to wait. I was taken back promptly by a friendly staff. Dr. Jones was professional, conversational, and amiable. His explanations were helpful. I appreciated the skilled care.

I could have not had a better experience starting when I walked through the door until I went home. Every single person I had contact with was amazing. Dr. Geist was fantastic, he had a wonderful upbeat personality along with being professional, thoroughly explaining the results and was very encouraging. I would never go anywhere else and am telling my friends to definitely go to this facility!

It's been about 8 years since my last procedure. I forgot how well Dr Gaines and his staff are. Everything went well, and I had the best sleep in such a short time!
Thank you , Doc!

They have been so helpful and listened to all my concerns and doctor Vitorsky is absolutely amazing. I got a colonoscopy and upper endoscopy done and it was such a breeze. They do an amazing job at making sure you’re comfortable and listened to.

Very friendly and courteous staff. Checkin was efficient and I was seen on time, although my appointment was first thing in the morning. Dr Saha was engaging and professional and gave me opportunity to ask questions. She clearly explained her thought processes and plan.
