Primary Care Internal Medicine and Medical Subspecialties

Welcome to Amarillo Medical Specialists.

Amarillo Medical Specialists is the largest private practice Internal Medicine group in the Texas Panhandle. We are focused on providing a patient centered approach, and we want to be your 'Medical Home'.

Dr. Ako Bradford's office is now accepting appointments for adult medicine patients at (806) 350-7308.

Congratulations are also in order for Dr. Bradford, who was chosen for the 'Texas Monthly' SuperDoctor 'Rising Star' listing of physicians in their July 2014 issue. He was the only Internal Medicine physician in our region chosen for this honor.

Dr. Bradford was born in Tougaloo, MS and graduated high school from the Mississippi School for Mathematics and Science in Columbus, MS in 1992. After graduating cum laude with a BS from Tougaloo College in 1996, he spent two years conducting research and publishing at the National Institutes of Health in Rockville, Maryland. Dr. Bradford subsequently attended the Virginia Commonwealth University / Medical College of Virginia School of Medicine in Richmond, Virginia. After graduating in 2002, he and his wife moved to Amarillo where he completed his Internal Medicine Residency at Texas Tech University Health Sciences Center in 2005.

Because Dr. Bradford has an aggressive desire to serve patients and assist them in functional health, he specializes in Primary Care Internal Medicine for adult men and women.

Dr. Kathleen Clark is now accepting appointments at the Southwest Anti-Aging Center.

This features the availability of bioidentical hormone replacement for women, testosterone therapy for men, evaluation of metabolic disorders, and medical weight loss therapy.  Dr. Clark is at our 1215 S Coulter location in Suite 202, and may be reached at (806) 350-7311


Janet Schwartzenberg MD and Tommie Buchanan FNP-C joined Amarillo Medical Specialists, effective February 4, 2014.

We are thrilled to announce that Dr Schwartzenberg and Ms. Buchanan are joining the AMS team!

By joining Carlos Plata MD, this will create a strong and well respected Rheumatology department at AMS. We expect to be able to expand our offerings of rheumatology diagnostics, procedures, and infusion services.

Dr Schwartzenberg and Ms Buchanan come to us from the Amarillo Diagnostic Clinic. Their existing patients are welcome their new practice, and we are working hard for a smooth transition to AMS. 

Dr Schwartzenberg and Ms Buchanan are 1215 S. Coulter St in Suite 200. For more information, you may call 350-7983.
