Dr. Krystal Harris completed her Oncology residency and Master’s degree at Oregon State University in 2014 where her research focused on Feline Oral Squamous Cell Carcinoma. She has spent the last 5 years in the Pacific Northwest working at a privately owned hospital and growing her family, but is returning home to Texas for family and sunshine! Dr. Harris completed her undergraduate work at Texas A&M while working as a veterinary technician in the ICU at their small animal teaching hospital. She studied veterinary medicine on the beautiful island of Grenada, where she returned a year later for a destination wedding.

Professional interests include targeted and alternative options to traditional chemotherapy and comfort care for pets with a cancer diagnosis. Outside of work, she enjoys gardening, yoga/ pilates, traveling, and spending time with her family.


I grew up having a veterinary technician for a mother, so I knew early on that my path would be in veterinary medicine. I followed her to College Station for undergrad when I finished high school because she was working on her pre-vet and started along the same path.


I took a bit of a detour and headed down to the Caribbean for vet school, where I met my husband. Then I did my internship and residency in oncology at Oregon State University.

One of the reasons I was drawn to oncology had to do with my first summer after my first year of vet school when I needed a summer job. My mom had a connection to the oncology service by our house, so I shadowed the doctors there and got paid to be an intern for the summer. They did chemo and radiation. The radiation dogs would come every day for their treatments, so you got extremely close to the animals and the families. They all came in wagging their tails every day, and each of them got hamburgers after their treatments. They were so happy despite the horrible downside of going through chemo and radiation. I really enjoyed that aspect of how close you get with the clients and the families that are going through cancer treatment.

It comes down to the relationships and getting to help make mostly older pets more comfortable for the time they have left. It's a lot of comfort care and hospice, and we also educate people and empower pet owners to feel like they're doing everything they can for that animal.

I pour my heart into my work. It's a difficult job, but it's really rewarding. Everyone should have empathy and compassion for the team that has dedicated their lives to taking care of sick pets.
