Dr. Deborah Aparicio

Hi, I am Dr. Deborah Aparicio, the owner of Clayton Valley Pet Hospital. Animals have always been my number one passion. I also love sports and music. I belong to a year-round triathlon team so you may catch me rushing in on my sports outfit or running out to catch a rock concert.

I am here to establish your trust with quality pet care. I have 30 years of experience with small animals, birds, and exotics. I am also trained in animal acupuncture and behavior. I am able to offer your pets the care you should expect from a veterinarian, the care your pets deserve.

Give me the opportunity to show you my skills as a veterinarian and as a compassionate person. I love my profession and you will see that in my work. My dogs are Dexter and Cricket, my cats are Orange Crush and Clayton, and I have an 18-year-old mare named Windy. Come in and meet my friendly staff. We welcome all new families and their pets.
Deborah N. Aparicio, DVM

Whitney Baty

Hello, I have been working at Clayton Valley Pet Hospital since 2014. I am currently in pursuit of my RVT license and have recently graduated from Veterinary Allied Staff. I have grown up with animals my whole life and enjoy working with them every day. My husband and I live with our two cats Spooks and Puddles.

Patrick Cogo

Hello Clayton Valley Pet Hospital Clients, my name is Patrick Cogo. Many of you may have seen me working around the hospital as a Veterinary Assistant for the past year as I pursued my education at Diablo Valley College and I have had the honor of meeting some amazing pets and loving owners. Now, I will be moving to Davis, California and pursuing a degree in Animal Science at UC Davis with a focus on becoming a Wildlife Veterinarian. Don’t worry! You’ll still see me around the hospital from time to time, assisting Doctor Aparicio wherever I can. I hope to utilize my newfound knowledge at UC Davis to bring your pets some of the best care.

George Hilwie

Hi! My name is George and pictured with me is one of my dogs, Norman. I have been working at CVPH since 2009, when I retired from United Airlines to pursue my love for animals. At the hospital I am sort of the Jack of All trades, working as assistant, kennel keeper, janitorial, yard work, and general maintenance. Besides dogs and cats I have been a rabbit lover since finding my first stray 20 years ago. I became a rabbit and guinea pig rescuer from then on. I also volunteered my Sunday’s from almost two years at the Oakland Zoo, working with the giraffes and elands. On days off from the hospital I also work at the Concord Pavillion. And during my free time you can find me gardening (my second passion), walking trails or biking!
