Meet our Doctors

Denise Kelley, DVM, DACVIM (SAIM)


Dialysis, Internal Medicine

I am originally from New England, but Washington, D.C. feels like a second home to me. I initially came to D.C. to attend college and worked for several years in business before accepting the fact that my true calling was veterinary medicine. I returned to New England to attend veterinary school at Tufts University and ultimately completed my internal medicine residency program there as well.

I am excited to be living in D.C. once again and rediscovering the city, as well as working along side previous colleagues from the University of Pennsylvania and Tufts University. Outside of the hospital, I enjoy spending time with my husband, exploring the outdoors, and traveling.

Clinical Areas of Interest

Why Do You Work at Friendship?

When I lived in D.C. the first time, I was actually a client at Friendship Hospital for Animals. My cat was diagnosed with a fatal disease so my visits to Friendship were always tough, but I remember how warm and dedicated every single doctor was during that difficult time. When I was applying for Internist jobs, I knew that Friendship was the place for me thanks in part to my own client experience, as well as the fact that I would be able to work alongside previous colleagues.
