Cailin Harro, DVM

Internal Medicine Intern

Internal Medicine

Since I was young, I have always had a love for animals and an interest in veterinary medicine. I am originally from Grand Rapids, Michigan, but I moved out to upstate New York for my undergraduate degree. At Ithaca College I was able to get involved with research in biology and volunteering with Guiding Eyes for the Blind to train service dogs. Helping to raise service dogs was a challenging experience that taught me that each animal is unique. Through my research I developed a love for physiology which pushed me to pursue a veterinary degree. I came back home to Michigan State University for veterinary school where I have found a passion for complex cases in internal medicine and neurology.

In my spare time, I enjoy yoga, hiking, and curling up on the couch with a good book and my rescue mutt, Benny. While I will miss the lakes in Michigan, I am excited to be in the D.C. area and would love any suggestions for your favorite local parks!

Why do you work at Friendship?

I first became interested in Friendship because of its reputation for excellent medicine and a collaborative environment. After talking with current doctors and interns at the practice, it was clear that Friendship prioritizes teamwork, mentorship, and patient care above all else. I knew that this would be the perfect place to start the next phase of my career!
