I would recommend Dr. Mathews to anyone I know that would need to see a gastroenterology specialist. Dr. Mathews is an excellent physician and I had referred others to see him.
I was impressed with Drs Hutain and Mathews. He was resourceful in obtaining my records from another provider on line and made his concise recommendations promptly. Both were very pleasant
just met him so far very happy
amazing dr and incredibly responsive and helpful staff. I loved my experience!!!!
Dr. Mathews was very kind and caring to me. The front office and nurse staff were also very kind and helpful.

Physician Bio

My father was a factory worker and had great ambitions for me. He spent almost half of his salary on my education. The day I was accepted into the India Institute of Technology, the world’s finest engineering school, was one of the happiest of his life. Imagine his disappointment when I quit after a year to go to medical school. It was very difficult to tell my father, but I knew I had a passion for medicine and making a difference in people’s lives.

The collaboration between St. Jude Medical Center and St. Jude Heritage Medical Group allows me to focus on medical advancements, and practicing at the state-of-the-art Knott Family Endoscopy Center ensures my patients have access to the newest technology and treatment options available today.

Offering the latest procedures with the newest techology is a vital component of my practice, but I believe it is equally important to treat patients the way I would want to be treated. I take the time to listen to my patients’ concerns, educate them about their options and work with them to improve their health and well-being. This is why I became a doctor.
