  • Sara Martinez, C.V.T.
    Practice Manager

    I was born in San Diego, CA, and moved to Tucson when I was 11 years old. I am a 2001 graduate of the Pima Medical Institutes veterinary assistant program. I began working for Ajo Veterinary Clinic in 2001. In 2006 I earned my national and state certification as a Veterinary Technician. I enjoy the challenges and rewards of helping our clients keep the furry members of their families healthy. I have a weakness for older dogs and orange cats. When not reading or spending time with my family, I enjoy Tucson’s diverse music scene. More recently I have returned to school to study business to become a more successful practice manager.
