Dr. Deborah Aparicio, DVM

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

Tara Reichert: Office Manager

My name is Tara Reichert, I am the practice manager here at Clayton Valley Pet Hospital. It is a pleasure to serve the people and pets of our community, assisting Dr. Aparicio and promoting our mission to provide quality preventative medicine.

I was fortunate enough to meet Dr. Aparicio when working at my first job in the veterinary field as a Kennel Assistant in high school. To own her own practice was always Debbie’s dream and I was promised a spot on the team should this dream come true. It is now well over a decade later and here we are!

When I’m not in the office you’ll usually find me at a rodeo with one of the 3 horses (Wyatt, Maverick & Texie Girl) in tow, or doing leatherwork under the watchful eyes of my 3 kitty ‘supervisors’ (Bitten, Scout & Bruce).

Thank you for allowing us to live out our dreams every day, the staff at Clayton Valley Pet Hospital looks forward to keeping your furred, feathered and fanged family happy and healthy for years to come!


Hello, I’m Tori. I have been working at Clayton Valley Pet Hospital as a Veterinary Assistant since 2015. I have lived in Concord all my life and have grown up caring for all sorts of animals. I‘ve had dogs and cats, as well as birds, fish, rabbits, guinea pigs, hamsters, and even a pet pig named Bacon! I love working here and meeting new furry friends, Doctor Aparicio has taught me so much over the years. I currently have 2 dogs of my own, Corkey & Jingley, and a cat named Fruitloop.


My name is Renee Gabrielle, I was born and raised in Morgan Hill, California until I moved to Contra Costa County 4 years ago. I have worked at Clayton Valley Pet Hospital since May of 2017 as the Lead Surgical Assistant. I have owned and worked with all different types of creatures since I was a little girl and have been fortunate enough to continue doing so. I currently have a 5 year old Chi-Weenie named “Luna” and a 2 & ½ year old black cat (that I raised from less than 24 hours old) named “Dwayne”. I also have a 45 gallon freshwater fish tank with 3 African Cichlids. I am incredibly grateful to have been hired by my amazing Dr. Aparicio whom also treats a wide variety of animals and reptiles. My favorite part of working at CVPH and a huge passion of mine is doing the dental cleanings.


Coming soon.

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!


Hello Clayton Valley Pet Hospital Clients, my name is Patrick Cogo. Currently, I am a PreVet Student Intern engaged in a meerkat study in Africa. 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.
