Explore our staff biographies to learn where we’re from, how we came to veterinary medicine, and why we love the work we do!

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!

She has always had a passion for animals, and this winter she will start school at Ross University School of Veterinary Medicine to earn her DVM and hopefully go on to specialize in veterinary ophthalmology. Grace also runs the breeding group Poindexter Border Collies, shows champion dogs, and hosts a private dog training program out of her home. When not at work or school, Grace can be found enjoying the outdoors with her four Border collies Caragh, Deakon, Stout, & Rubble, and her horse Keela.

Kelsey Long

Kelsey grew up in Davis, CA where she raised goats and pigs for 4-H and FFA. She came to SLO to study animal science at Cal Poly, and she is currently a senior with a concentration in veterinary medicine. In addition to working with companion animals and livestock, Kelsey also enjoys working with the horses in Cal Poly’s Equine Unit. Kelsey is in the process of applying to veterinary schools, and she hopes to pursue her DVM immediately after finishing her undergraduate degree. Kelsey’s free time is spent hiking and going to the beach. She has a cat named Maxi and a dog named Leia.

Brandy Kosters

Brandy discovered her love for animals while spending time at the lake with her family dog Alex, a black lab. She worked as a grooming assistant in Iowa for five years, where she also took on additional roles within the hospital. Soon after moving to the Central Coast, Brandy began to miss working with animals, and she started at AHSLO in August 2015. Since then, Brandy has become a familiar face when clients first enter the hospital. When not working, Brandy likes to spend her free time cuddled up at home watching Netflix with her black and white Shih Tzu named Chandler.

Hannah has lived on the Central Coast her entire life, and she has always been passionate about animals (especially bats!). She started volunteering at Santa Maria Valley Humane Society at the age of 13, and she has been working with animals in one way or another since then. Hannah completed her Associate’s degree at Cuesta College. She spends her free time relaxing with her dog, Daisy, and her two cats, Margo and Penelope.
