Why do you work at Friendship?

I was interested in returning to the DC area from having lived and worked in the area about 5 years ago. I knew about Friendship from living in the area before, and the hospital has an outstanding reputation across the country. The culture and values of the hospital, as well as providing the opportunity to live and work inside the District, made it stand out.

I engaged in biomarker research in feline heart disease during my residency. I look forward to continued collaborations on this project with my colleagues at the University of Illinois, as well as new opportunities for research with my colleagues at Friendship.
