Dr. Tanner Ross, D.V.M.- Medical Director

Dr. Ross joined our staff in 2012 after relocating from Washington. Dr. Ross grew up caring for animals on his family's cattle ranch in Wyoming. After attaining his undergraduate degree in animal Science at the University of Idaho, he went on to attend Washington State University veterinary college and graduated in the Spring of 2010. His pets include horses, dogs, goats, and the cat. He has been a great asset to our hospital with his caring and compassionate nature.


Dr. Maureen Rankin

Dr. Maureen (Mo) Rankin obtained her veterinary degree from The Ohio State University in May 2014. She grew up in California and Ohio, and practiced large and small animal medicine in Pennsylvania before relocating back to southern California with her two dogs, Trooper and Bruno. Her granddad, a retired veterinarian, inspired her to become a vet at a very young age, and she has enjoyed working with all types of animals, including cows, horses, goats, pot bellied pigs, and the occasional hamster or guinea pig. Her special practice interests include ultrasonography and emergency medicine, and in her free time she likes camping, hiking, winter snow-sports, and exploring new places with Trooper and Bruno.
