St. Luke's Residency Program

Resident Faculty

Fred Balis, MD, FACP
Program Director

As the Program Director for the St. Luke’s Residency in Internal Medicine program, he is committed to administrative and teaching responsibilities. He is board-certified in internal medicine at Medical Specialists of St. Luke’s. He received his medical degree and completed his residency from Washington University School of Medicine and is an Assistant Professor of Clinical Medicine at Saint Louis University.


Ravi Donepudi, MD
Associate Program Director

Dr. Donepudi is a board-certified Hospitalist at St. Luke's Hospital. He received his medical degree from JJM Medical College and completed his residency at St. Luke’s Hospital in 2007. He aligns residents and hospitalist groups so residents can receive high quality inpatient training experience. Since hospitalists are readily available in the hospital, residents can receive more quality time to discuss the patient information and pathology in person.


Delene Musielak, MD, FACP, FAAP
Associate Program Director

As a dual-boarded Internist and Pediatrician, Dr. Musielak will be able to bring a different perspective of medicine, especially for patients where the disease processes cross over from children to adults (cystic fibrosis, congenital heart diseases, etc.). With the advances in medicine, these patients are living longer and the transition from a Pediatrician to an Internist is crucial. Dr. Musielak earned her Bachelor of Science degree at Stony Brook University in New York and her Doctor of Medicine degree at Ross University School of Medicine. She then completed her four year combined Internal Medicine and Pediatrics residency training at the University of Missouri – Columbia.
