Gastroenterology Consultants of San Antonio

Hays L. Arnold, MD

Dr. Arnold, a former Lieutenant Colonel who served in the US Army for more than 11 years, joined our practice in July 2010. Dr. Arnold is skilled in all areas of gastroenterology, with special expertise in inflammatory bowel disease and GERD. Describing himself as nationalistic, or someone whose pride in his country moves him to action, Dr. Arnold was stationed at Brooke Army Medical Center, serving most recently as Chief of Clinical Services in the Gastroenterology Division. He was deployed in 2008 in support of Operation Iraqi Freedom.

Dr. Arnold is most passionate about teaching others, whether he’s instructing his patients about their health care choices or encouraging a medical student during challenging situations. Early on, Dr. Arnold gravitated toward medicine, even though he had an appointment to attend West Point and recruitments to play football. He most looked forward to being able to help and teach those around him. In his spare time, he enjoys participating in his children’s sporting activities and tackling home renovation projects. Dr. Arnold is married and has 4 children.

Dr. Arnold is a GI Doctor in San Antonio.

What His Patients Say

“Dr. Arnold is truly the kindest and most caring doctor I’ve ever had throughout my journey with Crohn’s disease. He is knowledgeable, and always makes time to explain anything or listen to your concerns. I honestly could not recommend a better gastroenterologist.” -Jennifer

“Both my mom and dad had their colonoscopy in late August and early September with Dr. Hays and they had an amazing experience here. Every staff member they came across were extremely friendly and accommodating. They have nothing but praises for the five star treatment they received. Thank you.” -Soo

“Outstanding doc! Made me feel at ease right from the start. I didn’t feel rushed at all. It seems most docs now try to rush you thru because of work load but Dr. Arnold answered every question thoroughly. I would highly recommend him to anyone!” -Michael
