Fun facts / Personal: Outside of work I enjoy exploring new restaurants around Baltimore County. At home I’m raising backyard chickens, which is surprisingly entertaining and keeps me grounded after a busy clinical day.
What I love about the program: I appreciate how collaborative Johns Hopkins is, especially the close working relationships between radiology, surgery, oncology, and pathology. Residents here are motivated and supported to take ownership of patient care while learning in a team-based environment.

As we work closely together to create a successful and rewarding academic year, we naturally build meaningful relationships and lasting bonds along the way. What makes it even more special is that we always find ways to have fun, celebrate one another, and enjoy the journey together!
