Hundreds of happy patients

The staff there were very friendly. Didn't have to wait a long time to see the Dr. I have been there before so decided to go back to them again for my procedure because I like the service they give.

I went to Hattiesburg GI for a 2nd opinion after suffering with numerous GI issues for 30+years since childhood. I saw Erin the nurse practitioner who immediately made me feel super comfortable. She was so nice and did not make me feel rushed and took time to actually listen to me and didn't make me feel like "just another patient" but somebody who mattered and that she really wanted to help. The Dr. I had been seeing since relocating to MS nearly 2yrs ago is nice but my chronic Illnesses and many GI conditions are difficult to treat and often many things do not always work which can be very frustrating for Dr.'s. I think many times they forget how frustrating it is for the person living each day with all of the illnesses. Erin came up with a plan right away and even mentioned something that had never been discussed with me in the over 30+ years that I've been sick each day. I was so excited leaving their office and finally had hope that maybe this would work and grateful that I'd been listend to by someone who was genuinely friendly and not fake nice. I will be happily calling this my new GI Dr. Office! 🙂

Have complete confidence in Dr Fox. He has not only seen me over the years but my husband, mother, grandmother, aunts, and uncles. Will continue to see him in the future. Thanks so much for such wonderful care of your patients!

About Hattiesburg GI

Whether you're 45 years old or over, have family history of colon cancer, or are at risk of colon cancer, colonoscopy screenings are one of the best ways to prevent and detect colon cancer. Additionally, a colonoscopy could help diagnose symptoms such as diarrhea, bloody stool, stomach pain, and more. A simple, 15-30 minute colonoscopy can provide valuable answers to your GI symptoms.

Inflammatory bowel disease (IBD) mainly refers to two conditions — Crohn's disease and ulcerative colitis — that together impact nearly 1.6 million Americans. An additional 70,000 new cases of IBD are identified in kids and adults every year. The majority of IBD patients receive a diagnosis by the time they're 35 years old. IBD is a long-term condition, and while it cannot be cured, it can be managed with the right treatment.
