Dr. Diana Cortez, DVM, Partner & Hospital Director 1993

Diana Cortez

Dr. Diana Cortez first joined our team when Dr. Mulvihill hired her as kennel attendant in 1994. During the course of her undergraduate studies and veterinary school, both completed at UC Davis, Dr. Cortez moved up to the position of veterinary technician assistant and later to that of veterinary technician. After graduating from veterinary school in the year 2000, Dr. Cortez completed a one year-long rotating internship in the Los Angeles area that focused on oncology, ophthalmology, internal medicine, and surgery. After completing the internship, she moved back to Sacramento and shortly afterwards returned to her home here at Sacramento Animal Hospital as a veterinary associate.

In 2006, Dr. Cortez became a partner in the practice along with Dr. Karen Mulvihill and Dr. Erin True. Together, they've continued to grow the practice and build a culture of teamwork, trust, and integrity. In 2011, Dr. Cortez stepped into her current role as our Hospital Director. Though it meant she had to cut back on time spent with clients and patients, something she had to think long and hard about, it has allowed her to help ensure Sacramento Animal Hospital continues to be the warm, family centered, reputable practice it has always been.

On her down time, Dr. Cortez enjoys spending time at her son's sports events and band performances. She also enjoys going to the movies, the local theater, and curling up with a good book.
