Meet Our

Team of Doctors

Dr. Joe A. Fong - SF Vet
Joe Fong, DVM – Medical Director

Dr. Fong joined Irving Pet Hospital in 2007 and serves as the practice’s Medical Director. He received his DVM from UC Davis and is a member of the California Veterinary Medical Association and the American Veterinary Medical Association.

A native San Franciscan, Dr. Fong says he could not imagine life as anything other than a veterinarian.

“There is an honesty that animals bring to our lives,” he says. “They accept us for who we are and don’t judge. It is that bond and the excitement of science and medicine that makes every day a new day.” Most of all, Dr. Fong says he enjoys being involved with patients from the time they are kittens and puppies and watching them grow up to become wonderful additions to the family.

At home, Dr. Fong and his wife have a child in elementary school and many pets they enjoy caring for, including two Old English Sheepdogs named Pepper and Bobby and a long-haired Dachshund named Magic. They also have several birds including Bourke’s parakeets Gabbie, Cassie, Gucci, and Charlotte, as well as a Blue Pacific Parrotlet named Cheep Cheep.

Anna DeVincenzi, DVM

Dr. Anna DeVincenzi is a general practitioner here at Irving Pet Hospital. She earned her undergraduate degrees–a BA in Psychobiology with a minor in Psychology–at the University of California at Santa Cruz in 1995. During her undergraduate studies she volunteered at the Long Marine Laboratory in Santa Cruz where she worked with sea lions for three years. She also worked as a volunteer at the Marine Mammal Center in Moss Landing. In 2001, Dr. DeVincenzi entered University of California at Davis School of Veterinary Medicine where she earned a Doctorate of Veterinary Medicine in 2005.

Dr. DeVincenzi’s areas of professional interest include medicine and surgery. She is a member of the California Veterinary Medical Association, American Veterinary Medical Association, Peninsula Veterinary Medical Association, and the San Francisco Veterinary Medical Association.

Raised in Los Altos, California, she says her desire to become a veterinarian started at a young age. “My family always had dogs and cats while I was growing up, and I experienced the joy that a pet can bring to your life,” she says. “I realized then that my love and compassion for animals and their welfare could be best expressed by becoming a veterinarian. Being a veterinarian combines my love for animals along with an avid interest in science and medicine.”

At home, Dr. DeVincenzi has a domestic shorthair cat named Clara. Beyond her animal care responsibilities, she enjoys most outdoor activities such as hiking, camping, skiing, and biking. She also likes to travel, bake/cook, and dance.

We are very pleased to have Dr. Bill Rivers as our consulting radiologist. Dr. Rivers graduated from the UC Davis School of Veterinary Medicine in 1984 and, after an internship with Dr. Steven Ettinger in Los Angeles the following year, he practiced general small animal medicine in the San Francisco Bay Area for several years. Dr. Rivers then completed specialty training and a PhD in Radiology from the University of Minnesota. He became board-certified as a specialist in Veterinary Radiology by the American College of Veterinary Medicine in 1995. After being on staff at two veterinary schools and a private specialty practice, he established his Bay Area Consulting practice in 1989.

Dr. Rivers performs the more complicated ultrasound examinations on our patients and helps us interpret our more complicated x-ray studies on our patients. His extensive training and experience helps us to provide the highest level of care for our patients.
