Our Veterinarians

Dr. Liz Grey

Veterinarian, President and Hospital Director

Dr Grey was born in New York, but her family moved to San Diego when she was 12.  While she was growing up, her family did a lot of rescue work with animals.  Her father impressed upon her at an early age that once you commit to an animal, you are responsible for providing it with the best care possible.  Dr Grey knew at an early age that becoming a veterinarian would combine two of her favorite things – caring for animals and solving mysteries.

Dr Grey did her undergraduate work at San Diego State University, receiving her Bachelor of Science in Zoology in 1982.  She was the number one graduate in her department and part of the Phi Beta Kappa National Honor Society.  She went on to University of California at Davis, graduating in 1987 as a Doctor of Veterinary Medicine.  Soon after that, she came home to San Diego.  She began working at Carmel Mountain Ranch Veterinary Hospital in 1990, and went on to purchase the hospital in 1994.

Dr Grey’s special interests in medicine include dermatology and ophthalmology. She loves caring for geriatric patients and helping them live longer, more comfortable lives. And of course she loves seeing new puppies and kittens!

At home, Liz lives with her daughters, Sara and Becca. Sara is an excellent volleyball player and will be heading off to college in a few years. Becca likes fencing and has her eye on Duke University. Liz and the girls have a menagerie of pets: 9 dogs, 6 cats, 2 horses, 2 lizards, a cockatiel, an aviary of parakeets, and the latest rescue, Scarlett the Pig.

Liz has been a certified scuba diver for over 20 years and has been all over the world diving. She also enjoys surfing (although she’s not very good at it!) and mountain biking with her family.

Dr. Cliff Matsuda


Dr. Matsuda originally intended to get into human medicine, but got a job working at the veterinary department during his schooling at the University of California Davis and got hooked on veterinary medicine. He ended up switching his studies to the animal world and now works as an Associate Veterinarian at Carmel Mountain Ranch.

Dr Matsuda was born in Denver and raised in Los Angeles.  He moved to San Diego 16 years ago to start an emergency care practice for animals, which he sold five years ago.

Dr Matsuda loves performing C-sections, because of the challenging anesthesia.  He also enjoys critical care and feels the stabilizing of critical patients is very rewarding.

At home, Cliff lives with his sons, Tristan, who aspires to be an astrophysicist, and Alex, who wants to be a rock star drummer.  Their pets include a cat named Ninja (who thinks he is the family provider), a bearded dragon named Ladon, a parakeet named Tweetie, a tarantula, a scorpion and Madagascar Hissing Cockroaches.

Cliff is a sports-aholic and outdoorsman.  His memorable moments include climbing Mt Chimborazo in Equador, whitewater kayaking in Colorado, windsurfing in Maui, Ride the Rockies (a 500 mile bike ride), Ultramarathon Rim-Rim-Rim (double crossing the Grand Canyon) and Full Ironman in Arizona.  He also enjoys rock climbing, rollerblading, hockey, tennis, skiing and snowboarding, to name just a few!

Dr. Ashbaugh enjoys all aspects of practicing veterinary medicine; his special areas of interest include dermatology, dentistry, and surgery. He is passionate about client education and preventive medicine.

John and his wife, Monica, are the proud parents of four wonderful children – Melina, Konrad, Sebastian, and Declan. They share their home with two Chesapeake Bay Retrievers, Archie and Grizzy, a cat names Seamus, and a myriad of tropical fish.
