Meet Our Medical Directors

Peter Aran, M.D.
Senior Vice President - Chief Medical Officer

Dr. Aran received both a Bachelor of Science and medical degree from the University of Iowa. He continued his specialty training in internal medicine at the University of Iowa Hospitals and Clinics. He received subspecialty training in gastroenterology at the University of Chicago, followed by a fellowship in liver disease and later taught at the University of Chicago as an assistant professor in medicine.

Prior to assuming his current position, Dr. Aran was a gastroenterologist at Saint Francis from 1990 through 2009. He was involved in a number of committees and leadership activities related to clinical quality improvement, as well as serving on the Saint Francis Health System Board of Directors from 1996 to 2009.

His wife, Sofia, has a Ph.D. in neuropharmacology. Together they have three sons in college and a daughter in high school.

Stan Schwartz, M.D.
Medical Director - Warren Clinic

Dr. Schwartz was a native New Yorker who only ventured as far west as Pittsburgh, Pennsylvania for residency and fellowship after completing medical school in New York City. Stationed in Oklahoma in the military for two years, he tried moving back east, but missed the open spaces and big skies of Oklahoma. He returned to Oklahoma permanently more than 25 years ago and started an infectious diseases group practice that he managed until becoming the Medical Director of Warren Clinic in 2004.

Saint Francis Health System is a well-respected nonprofit institution in northeastern Oklahoma that has been under the same ownership for nearly 50 years. Schwartz says, "As an integrated health delivery system with great financial stability, Saint Francis and Warren Clinic allow physicians to do what they do best: Concentrate on treating patients in a mission-driven, value-oriented healthcare system."

"Tulsa is truly a great place to live and work. We have a great stable housing market that never boomed and never busted. You can have a wonderful, affordable place close to your work without a long commute as part of your life," he says. "Tulsa has wonderful recreational opportunities nearby-lakes, preserves, state parks -all within a short drive."
