“I came here because of the patient-centered approach to care, provided under one roof and approached as a team,” says Dr. Peter Baik, FACOS, Lung Cancer Institute Leader at Cancer Treatment Centers of America® (CTCA) and Thoracic Surgeon at Southwestern Regional Medical Center. “I also value the incorporation of integrative modalities to help combat side effects.”

He completed his Doctor of Osteopathic Medicine at Kirksville College of Osteopathic Medicine in Missouri in 2005 earning several academic awards.
