Mount Carmel's Internal Medicine Residency Program is led by a dedicated group of clinicians that encompasses six full-time internal medicine faculty and over 30 key subspecialists. All members are board certified and most are recertified in internal medicine and/or their particular specialty and continue to see private patients.
