I would like to welcome you to the home page for the Internal Medicine Residency at Bon Secours Mercy Health - St. Elizabeth Youngstown Hospital. Thank you for your interest in our program.

We began training Internal Medicine residents in 1967 and have a rich tradition of producing excellent Internists. Our graduates are well prepared for careers in traditional primary care and hospital medicine, as well as further sub-specialization through fellowship training. Over the past 10 years, residents from our program have obtained fellowship positions in cardiology, hematology/oncology, endocrinology, pulmonary-critical care, nephrology, infectious disease, and gastroenterology. We are very proud of the accomplishments of our residents, both during their training and later in their careers.

Through a careful selection process, we accept eleven new residents each year. We are very much a multi-ethnic program and enjoy the diverse cultural atmosphere we have created. Our Annual International Dinner is a yearly highlight!  

We have an extremely dedicated and committed teaching faculty, robust scholarly activity and a supportive administration. Each year many of our residents present their clinical research or clinical vignettes at local, regional, national and even international meetings. Our program was awarded the Silver Medal for Research by the Ohio ACP in 2015 and the Gold Medal in 2017 and 2018!

Please take a few moments to browse through the pages of our web site. I think you will be impressed with what our program has to offer!
