VCA Central Animal Hospital

Joyce Riehl-Voss, Ph.D, DVM, Associate Veterinarian

DVM, University of California, Davis
BA, Stanford University


After growing up in Los Angeles, I moved to northern California to attend college. I graduated from Stanford University in 1997 with a BA in Human Biology, and spent a few years afterwards doing research and working as a technician in a veterinary emergency clinic. In 2001, I began my dual degree training at UC Davis to get my DVM and PhD in Pharmacology. I graduated in 2006 with both degrees, and moved back to Southern California immediately afterwards.

We share our Upland home with our rescued two cats and dog. Jammer is an orange tabby domestic short hair who had been hit by a car as a stray when he was a year old. Karma is a black domestic medium hair who came to be my adoptee when she came to the clinic where I worked as a technician, in need of an emergency C-section. Our dog, Pepper, is a Border collie/German short-haired Pointer mix who had Parvo and was abandoned as a puppy.

When I am not at work, I spend my time with my husband and our two sons. I enjoy hiking, SCUBA diving, camping, traveling, music and food (especially chocolate and ice cream).


Specialty Care

Sometimes sick or injured pets need the care of a veterinary medical specialist. When that happens, VCA specialty hospitals work closely with the general practitioner veterinarians who refer cases to us in order to provide seamless veterinary care to your pet. When your pet is facing any kind of serious illness or injury, our specialty referral hospitals will provide the compassionate and expert care your beloved pet needs.

Our goal is to make sure that when you and your pet are in need that you have access to board certified specialists who are up to date on the very latest developments in their field. In our state of the art hospitals, our specialists also have access to the most sophisticated diagnostic and treatment tools and techniques from ultrasonography and endoscopy to CAT scans and even MRI.

As part of the VCA family, we have over 83 specialty hospitals across the US and Canada which provide referral specialty care, so there may be one near you. Our specialized services include: behavior, cardiology, critical care, dentistry, dermatology, integrative medicine, internal medicine, neurology, oncology, ophthalmology, radiology, rehabilitation, reproduction, and surgery.
