Dr. Cody Lewis, DVM – Practice Owner/Medical Director

Dr. Cody Lewis grew up in Northern California, where his father was a farrier (horseshoer) and raised livestock. After being raised around animals and inspired by his father’s love for them, he was driven to pursue a career as a veterinarian. He attended Cal Poly for his undergraduate studies in biochemistry and instantly fell in love with the Central Coast. He then went on to complete his Doctorate of Veterinary Medicine at Kansas State University.

As the owner of Animal Hospital of San Luis Obispo, Dr. Lewis works with small animals and practices strict guidelines issued by the American Animal Hospital Association (AAHA). At AHSLO and our sister hospital, Primary Care Animal Hospital in Arroyo Grande, Dr. Lewis and his team hold themselves to the highest standards in veterinary medicine and strive to deliver excellent care to every pet. Why? Because pets deserve nothing less!

Dr. Michael O’Hara, DVM – Associate Doctor

Dr. Michael O’Hara grew up in Orcutt, CA and studied molecular biology and biochemistry at the University of California Santa Cruz. He initially began working in the local veterinary medical community as a veterinary technician, and he went on to earn his Doctorate of Veterinary Medicine at Western University before returning to the Central Coast to practice. In his free time, Dr. O’Hara enjoys golfing and hiking with his wife Katie and three dogs.
