Katie Lock, DVM, MS

Dr. Katie Lock, a member of the internal medicine team, decided to become a veterinarian as a child. “Growing up, we didn’t have many veterinary clinics around where we lived. When my childhood dog was hit by a car and we had nowhere to take her, it was then that I decided to go into veterinary medicine. I never wanted anyone else to feel the heartbreak that I had felt.”

Born in Birmingham, Alabama, Dr. Lock achieved her Bachelor of Science all the way up to her Residency in Small Animal Internal Medicine at Mississippi State University. Dr. Lock spent time in private practice before pursing her specialty training in internal medicine, with particular interest in hematology, immune-mediated diseases and infectious diseases.

In Internal Medicine, her primary goal is to provide the best care possible while striving to guide owners through difficult decisions to help give their pet the best quality of life possible.
