    Casey Ireland is the Thayer Assistant Chief of Service for 2020-21. She is originally from Chattanooga, TN and attended the University of Georgia for undergrad before returning to Tennessee for medical school at the University of Tennessee College of Medicine. She chose the Osler program because of the absolute commitment to excellent patient care demonstrated by residents and faculty on her interview day. Casey completed the first year of her fellowship in cardiovascular medicine at Brigham and Women’s Hospital prior to returning to Baltimore for ACS year. Outside the hospital, she enjoys running, watching college football (go Dawgs!), and spending time with her husband Will.

  • Rohan Shah, MD, Janeway Firm

    Rohan grew up in Calcutta, India and moved to Baltimore initially for his undergraduate education. He was excited to return to Baltimore for residency, drawn to the Osler Program by the unique teaching environment fostered by the firm system, the clinical competency of the residents and the degree of autonomy offered by the program. The camaraderie between the residents, the opportunity to learn from exceptional peers and the breadth of training across multiple medicine subspecialties were the highlights of his time as a resident. As an ACS, he feels honored and privileged to work with some of the brightest residents as well as an incredible group of faculty, and is excited to contribute to the next class of outstanding Osler residents. Rohan spent a year as a cardiology fellow at the Cleveland Clinic and will be returning to complete his fellowship training following his ACS year. Outside of the hospital, Rohan loves playing and watching sports, and spending time with his wife, newborn son, and dog.
