David Haas, VMD

Internal Medicine Intern

Internal Medicine

I grew up in Wayne Pennsylvania, a suburb of Philadelphia. I attended Villanova University for my undergraduate degree in biology and after working for two years in the field post-graduation I attended the University of Pennsylvania School of Veterinary Medicine. In my time prior to veterinary school, I worked as a technician in both General Practice and in Emergency at a Referral Hospital in Southern New Hampshire. I currently have a 4-year-old lab mix named Saul and a 10-month-old kitten named Shoshana. In my free time I love discovering new places to eat in D.C. with my fiancée Chelsea, going hiking, and watching movies.

Why Do You Work at Friendship?

I was drawn to Friendship because of their excellent reputation in both clinical care and in the quality of the staff. The care and attention that the staff shows to their patients as well to their  co workers is unparalleled. I am excited to develop my skills and work with the wonderful people of D.C.
