Joe Fong, DVM

Joe Fong, DVM

Owner

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.

Lauren Silverman, DVM

Lauren Silverman, DVM

Associate Veterinarian

Dr. Lauren Silverman joined Irving Pet Hospital as an Associate Veterinarian in June 2025. She has special interests in internal medicine, dentistry, dermatology, and behavior, and is a proud member of the California Veterinary Medical Association. For Dr. Silverman, the most rewarding part of veterinary medicine is building lasting relationships with pets and their families.

Originally from Mountain View, CA, she earned her Animal Science degree from Cal Poly Pomona in 2011 and her Doctor of Veterinary Medicine from Western University of Health Sciences in 2015. Her passion for the field began early, inspired by her childhood dog Frisky, whose frequent vet visits introduced her to the compassionate care and problem-solving at the heart of the profession.

Outside of work, Dr. Silverman enjoys playing ultimate frisbee—something she’s done around the world since college—along with reading and participating in a book club. She and her husband share a special bond over their late dog Rufus, who played a key role in bringing them together. At home, she stays busy with their two young daughters, both of whom already dream of becoming veterinarians one day.
