Dr. Michael Thomas says he joined the staff of Cancer Treatment Centers of America® (CTCA) in Tulsa in 2006 because of the hospital’s commitment to excellence and its collaborative, patient-focused culture. He performs general surgery and oncologic surgery.

“The fact that cancer patients see a medical oncologist, a surgeon, a radiation oncologist, a plastic surgeon—and their case may be discussed at a conference where perhaps 12 to 15 doctors are around the table, reviewing management and treatment? That means that we consider all available options,” Dr. Thomas says.

Dr. Thomas says he takes time to get to know his patients on a personal level. “I say, ‘I’m going to walk with you through the whole process, and we are going to take care of you,’” he says.

After completing a bachelor’s degree in respiratory care at the University of Central Arkansas, Dr. Thomas earned a medical degree from the University of Arkansas for Medical Sciences in Little Rock. He then completed a residency in general surgery at the University of Kansas School of Medicine in Wichita, where he trained with breast surgeons and helped author a research report on aneurysm repair, published in the Annals of Vascular Surgery. In 2001, he was voted the medical school’s Outstanding Chief Surgical Resident.

Dr. Thomas is board certified in general surgery by the American Board of Surgery and is a Fellow of the American College of Surgeons. He is a member of the American Society of Breast Surgeons, the American Medical Association and the Society of Laparoendoscopic Surgeons.

In addition to caring for patients at CTCA, Dr. Thomas serves as chairman of the Department of Surgery at the Oklahoma State University Center for Health Sciences. He credits his grandmother, a nurse who cared for patients with chronic diseases, with inspiring his passion for medicine. “I look at this not just as a job,” he says. “For me, I look at it as a calling.”
