Christine Stone-Payne, DVM/Owner

I attended veterinary school at Michigan State University, graduated in 1978, and moved immediately to California with my husband. I have been in practice in Alameda County since then, and have been here at Mission Valley Veterinary Clinic since 1994. In my spare time, I have been president of the local county veterinary association, and also president of a national organization, the Association for Women Veterinarians Foundation. I currently am Awards Chair for that group. At home, I currently have 2 cats, chinchillas, birds, and fish. I enjoy seeing pocket pets (with fur) as well as dogs and cats at work.

Dr. Chris Stone – Payne is a member of the House Rabbit Society.


Julie Dizon, Practice Manager/Owner

I have been a manager in the Veterinary Field since 2003 and I have been the manager at Mission Valley Veterinary Clinic since February of 2006. I am a member of the Veterinary Hospital Manager’s Association. My furry family consists of a  lovable, rescued mutt Dottie and 2 wonderful cats, Lily Belle and Raisin. My love for animals and knowledge of their care continues to grow and I look forward to building on my experience with the clients and staff of Mission Valley Veterinary Clinic.


Stella Vargas, Lead Veterinary Nurse

I have been at Mission Valley Veterinary Clinic since November 2014. I have been working in the field for over 6 years and hold a passion for the exotic animals.  Most of my veterinary experience has been in specialty and emergency care.  On my spare time, I love to paint and spend time at music festivals.  My future plans include visiting the Buddist Temple in Thailand and receiving my RVT license.  I dream to one day work at an exotic animal and bird rehabilitation unit in Guatemala, where my family is originally from.


Cameron Campbell, RVT

I graduated from Carrington College in August of 2016 and received my AS degree in Veterinary Technology.  I have been employed at Mission Valley since February 2016.  I have been interested in animals from a very young age.  I used to spend countless hours watching Animal Planet.  Unfortunately, I do not have my own furry friend at the moment, but I hope to add a corgi to the family in the future.


Andrew Paratore, RVT

I graduated from Carrington College in May of 2014.  My interest in working with animals began when I was young from helping my aunt with grooming.  Being Deaf does not stop me from giving quality care that your pet needs.  I aim to improve communication between the doctors and the deaf clients.  During my off hours, I enjoy reading, studying Japanese and watching shows online.


Jerardo Silva, Veterinary Nurse/Customer Service Rep

I am currently pursuing a career as a registered veterinary technician.  I have always liked animals ever since I was a child and I am excited to finally work in a field that I love.  I look forward to learning ways to help all types of animals and hopefully one day be able to run my own veterinary practice.

I have been in the veterinary field since 2010 as both a veterinary technician and a receptionist.
