During medical school, Alan began traveling to Mexico for medical mission trips and those experiences set a course for the future. After residency, he began to travel regularly to Central America serving the people of Nicaragua and Honduras. Those travels helped inspire the dream of Heal the City Free Clinic in Amarillo. Heal the City is a free clinic that provides medical care to the uninsured of Amarillo and connects them to existing medical resources. The vision of the clinic is to communicate the love of Christ to patients and volunteers alike. The clinic has enjoyed success due to collaborative relationships with local foundations, hospital systems, medical and pharmacy schools, and the generous Panhandle community. The chronic care clinic at HTC enables access to care for the uninsured and provides comprehensive care for chronic illnesses and behavioral health needs.

Dr. Keister has been recognized for his work with Heal the City. He received Texas Medical Association’s John P. McGovern Champion of Health Award. He also was awarded the Texas Education Agency’s Heroes for Children Award. The American College of Physicians awarded him the Community Service and Volunteerism Award. He won the 2018 Baylor Line Foundation George W Truett Distinguished Service Award. In 2019, he was honored with American College of Physician’s Oscar Edwards Award for Volunteerism. In 2023, he and his wife, Vicki, were awarded the Pro Texana Medal for community service from Baylor University.

In his spare time, Alan enjoys spending time with his wife and 4 daughters and expanding family. Besides volunteering, Alan enjoys traveling, hunting, fly fishing, reading, and cheering for the Baylor Bears.
