Letter from the Director

Dear Prospective Applicant,

I would like to thank you for visiting the home page for the Transitional Year Residency at Mercy St. Elizabeth Youngstown.

This program is fully accredited by the ACGME. Established in 2004, the program, with four PGY1 positions, is co-sponsored by the Internal Medicine and General Surgery Residency Programs, both of which are long-standing, ACGME accredited programs within the Institution.

The purpose and objective of the Transitional Year (PGY1) is to provide a well-balanced graduate medical educational program, both clinical and didactic, so that you have a strong clinical background to continue your training.

Our graduates have gone on to complete residencies in radiology, anesthesiology, physical medicine and rehab, dermatology, emergency medicine, neurology, internal medicine, ophthalmology, and family medicine.  Some of our residents have returned back to Youngstown after completion of their training in order to continue their medical careers here. We are very proud of the accomplishments of our residents, both during their training and later in their careers.

Please take some time to browse our website.
