Brian K. Cooley, MD was born in Washington, D.C. and grew up in suburban Maryland. He graduated from the University of Maryland with a bachelor’s degree in Biochemistry. Dr. Cooley received my medical degree from the University of Maryland in Baltimore.

He moved to Texas in 1982, and has lived here ever since. Dr. Cooley trained in Internal Medicine at Parkland in Dallas, and received his Gastroenterology training at the University of Texas Health Science Center in San Antonio. He is board certified in both Internal Medicine and Gastroenterology.

Dr. Cooley is a founding member of Digestive Health Associates of Texas. He has been in private practice in the Plano since 1988, and is proud to have raised his three beautiful daughters here.

Dr. Cooley is one of the most caring doctors you’ll ever come across. With a calm and informative demeanor, he helped guide me through a 3-month hospital stay for GI issues. Even though he was on a team of doctors caring for me, there were times he would come in on his day off just to check on me. DHAT is a great place with many fantastic doctors, but Dr. Cooley is right at the top.

I have been having some stomach issues for a while now and finally went to see Dr. Brian Cooley. He was very knowledgeable and friendly. He definitely took the time to explain what was going on, the tests he was going to do, and next steps. I ended up having to get a colonoscopy, which wasn’t awesome but not too bad. I am very glad I went to see Dr. Cooley and will definitely continue to see him. If you are having GI problems, I would definitely recommend to my family and friends.
