The staff did a great job from contacting me for scheduling, to rescheduling to meet my needs was fantastic. And everything they did the day of my procedure turned out great. Of course the last part was verified by my driver, but I can verify that Dr. Henry sat and talked to me at length before the procedure. He answered all my questions and made me feel comfortable. I highly recommend Dr. Mark E Wilson and the staff at GI Associates & Endoscopy Center."

I was seen in a very timely manner, and everything was clearly explained to me.

"My routine visits are every 5 years but the staff at GI Associates never disappoints me. They are always courteous, prompt and kind before and after my procedure. Dr Reeves is so reliable that I live out of town but I travel back to Mississippi because I know I'm getting the best treatment and care every time my annual appointment arrives for GI Associates."
"Awesome service from everyone on the team. I have a few suggestions for an even better experience. Suggest making sure everyone is aware that the appointment time is one hour different from procedure time, especially if your appointment is at noon. As a patient, the 1:00 PM time slot for the procedure can be very tasking especially if on a liquid diet for a period of time. Additionally, staff or primary should provide options for prepping for the procedure-one gallon drink versus 2-16oz drink. Dr. Underwood was absolutely amazing, procedure was done within the hour...thank you!!!"
"Dr. Runnels is great with the most professional and knowledgeable staff anyone could ask for. I've used them numerous times and have been very well pleased. Patients are treated like family by Dr. Runnels and staff."
"I would recommend GI Associates and Endoscopy Center to anyone in need of GI services. They are so caring and professional. They go the extra mile to make you comfortable and completely cared for. Dr. V Reeves is a great doctor. Probably one of the best doctors I’ve ever had. I would highly recommend her and her staff. I’ll definitely use her and the center again on my next check up. Thank you Dr. Reeves and staff for taking such great care of me 😁"
