View Bio

Dr. Sarah Mihalek grew up in Redwood City and from the age of 4, knew she was going to be a veterinarian. She achieved a Bachelor’s degree in Animal Science from Cal Poly Pomona. In her senior year in college, she had doubts about practicing animal medicine and considered human medicine instead. She became certified in phlebotomy, worked in a human hospital for a short time, then promptly decided veterinary medicine was the path for her. She moved to the island of Grenada in the West Indies for veterinary school where she also completed a Masters in Wildlife Conservation and Medicine and was lucky enough to get to spend some time in Uganda for that program. From there, she moved to upstate New York for her clinical year of veterinary school at Cornell. In the beginning of her career, she practiced mixed animal medicine in the Midwest. She returned to California in the beginning of 2012 and has been practicing all around the state since. She loves to say she hasn’t met an animal she won’t treat (she has been known to perform surgery on all sorts of animals including coati, fish, chameleons, and everything in between). These days her interests are focused around improving the quality of life for her patients through a multimodal approach with the hope of decreasing pain and discomfort and also improving their ability to be independent and get around comfortably. She has completed certification from the Canine Rehabilitation Institute in veterinary acupuncture and rehabilitation therapy. Here at SAGE, her skills are put to work in the Urgent Care, Emergency, and Rehab departments.

In her off time, she enjoys anything that takes her outdoors, but most of all, she loves to hike. She can often be found in the gym moving some heavy weights or in the yoga studio. She shares her home with her three rescue French Bulldogs, Newt, Toad, and Frannie.
