Established in 1985 our Internal Medicine and Pediatrics Residency Training Program has a long-standing tradition of combined training excellence.  Our program trains 40 Med-Peds residents (10 per class) producing a diverse and supportive community of resident physicians. Between The Ohio State University and Nationwide Children's Hospital, we boast a nation-leading 80+ Med-Peds trained faculty representing nearly every Division within Internal Medicine and Pediatrics.  Our robust Med-Peds presence provides residents ample opportunities for mentorship as well as exposure to many combined, general, and subspecialty career pathways including a large offering of transition focused fields.  Nationally ranked free standing, tertiary care facilities afford residents exposure to cutting edge medicine and research. Our free standing, dedicated, multidisciplinary Med-Peds Resident Continuity Clinic provides residents an innovative ambulatory training experience.

Goals and Experience

Our goal is to train highly skilled and compassionate professionals, and we provide an environment for those physicians to achieve this goal. Our residents are responsible for the care of patients with a wide variety of medical illnesses, ranging from those routinely encountered in primary care practice to those seen only in the tertiary care setting. The Ohio State University Wexner Medical Center (OSUWMC) hospitals and Nationwide Children's Hospital (NCH) serve the combined roles of urban community hospitals, indigent care providers and referral centers for central and Southeastern Ohio. Residents have carefully supervised and graded patient care responsibility in a variety of educational settings at these hospitals and in faculty-staffed outpatient care offices.

Additional primary care and ambulatory care experiences are offered during rotations in the outpatient Veterans Administration Clinic and at several rural community clinics. The greater Columbus area has ten med-peds private practices, many of the physicians being graduates of this program. Many of these practices participate in an educational program called Internal Medicine-Pediatric Education in Community Sites (IM-PECS) where PGY2 to PGY4 residents spend a half day per week caring for patients in the private office.

Our Leadership


Margaret Chase, MD

Residency Program Director

I grew up in Alexandria, Virginia. I fell in love with the Med/Peds program at OSU/NCH. I was drawn by the people and the opportunity for such great training. Through residency, Med/Peds training gave me immense preparation and appreciation for the diversity of patient issues and management. I became program director in 2014.

I enjoy spending time with my “Med/Peds family”– they are some of the finest people I’ve ever known.

Our Chief Residents


Matt Emery, MD

Chief Resident

My decision to come to OSU/NCH for residency was one of the best choices I've ever made. I trained at Wake Forest School of Medicine for medical school, and my wife and I were looking to move closer to her family in Ohio for residency. My career interests are combined adult/pediatric hospital medicine, medical education, and cost-effective care. Columbus is such a great city. When I'm not working, I love spending time with my wife and son, running, gardening, backpacking, and trying new food and craft beers.

Mary Ryan, MD

Chief Resident

I went to The Ohio State University for medical school and loved everyone I met in Med-Peds making it an easy decision to stay here for residency. My favorite parts about our program are the strong training and the family bond I've forged with other residents and mentors. I am pursuing primary care and can't wait to take care of the entire life spectrum! In the meantime, I'm continuing to cultivate my growing jungle of indoor plants and ride my bike whenever possible.
