As a radiologist at Cancer Treatment Centers of America (CTCA) at Southwestern Regional Medical Center, Dr. Timothy McCay plays a critical role in our patients’ care. He performs minimally invasive procedures using some of the most sophisticated, medical imaging tools and software available. These intricate procedures help our oncologists diagnose and treat our patients.

Dr. McCay received an osteopathic medical degree from the College of Osteopathic Medicine at Oklahoma State University. Prior to that, he completed two undergraduate degrees—one in nuclear medicine at the University of Oklahoma Health Sciences Center and the other in chemistry. While working on a second bachelor’s of science degree, Dr. McCay conducted research on nuclear medicine cardiovascular imaging.

Dr. McCay completed a residency in radiology at Oklahoma State University Medical Center (formerly known as Tulsa Regional Medical Center), where he also served as Chief Intern.

Before joining our staff of compassionate cancer experts, Dr. McCay helped establish a teleradiology practice at Oklahoma State University Medical Center. This allowed diagnostic images to be electronically transmitted among 14 Oklahoma hospitals. Dr. McCay also gained significant experience as a nuclear medicine technologist at Presbyterian Hospital of Dallas. In addition, he worked as a chemist and director of two district labs for Halliburton, and spent two years working in respiratory therapy.

In his spare time, he enjoys breeding and showing horses, and spending time with his family.
