Dr. Donald Aga | Medical Director

I’m a native Texan and I received my bachelor’s degree in chemistry from Baylor University in 1990. I then attended the University of Texas-Health Science Center here in Houston, where I also did my residency in internal medicine. As a physician, I have several roles in the medical community. I’m an assistant professor of internal medicine at the University of Texas-Health Science Center and a clinical instructor of general medicine at Baylor College of Medicine. But, my primary role is caring for patients at Kelsey-Seybold Clinic, which I’ve been doing since 1997. Since 2007, I’ve served KelseyCare Advantage as medical director.

As medical director, my job is to oversee the quality of the medical care that our members receive. One of my many priorities is to develop new programs and find creative ways to improve care.

Because my clinical interests include preventive medicine and wellness, I am especially proud of our successes in the area of prevention. We place a heavy emphasis on reaching out to those patients who haven’t had recent physicals or who are due for lab tests. By doing this, KelseyCare Advantage is in a strong position to catch undiagnosed conditions in our patients before they have progressed too far and, thus, help our patients to live healthier, more satisfying lives.

For me, one of the best things about KelseyCare Advantage is our close collaboration with Kelsey-Seybold Clinic and its doctors. Our members report that they enjoy the convenience of the many Kelsey-Seybold locations and the coordination between the primary care doctors and specialists. And, the doctors like caring for Medicare Advantage patients because they know the patients will have comprehensive coverage when they need it.

I really enjoy my job at the health plan and I’m proud to be the medical director of a plan with such a high member satisfaction rating.
