Our Doctors

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.

Lilliam Alfaro, DVM

Lilliam Alfaro, DVM

Chief of Staff

Lilliam Alfaro was on her way to law school when an epiphanic encounter with a pigeon on a sidewalk diverted her towards veterinary medicine.
 
Overcoming a carefully curated liberal arts/political science degree in order to be considered as a candidate for entry into the field required a second go around at undergraduate school.  Dr. Alfaro tucked her political science degree from Barnard College under her arm and started undergraduate studies again; grounded by a deep love of chemistry she completed the course of study required for possible entry into veterinary medicine. The effort was not in vain.
 
Since graduating from the Virginia Maryland Regional College of Veterinary Medicine in 2002, Dr. Alfaro has been fortunate to work in many sections of the profession and considers each experience to have been invaluable in forming her approach to the practice of the science and art that is veterinary medicine.
 
Most recently, the mother of three teenagers has been an emergency clinician at North Peninsula Veterinary Emergency Clinic where with respect for the patient and compassionate consideration for the client, Dr. Alfaro has spent the last five years serving the San Mateo community.
 
With her, Dr. Alfaro brings an adherence to a team based approach at all levels of the patient-client-staff experience, guided always by her genuine love of and advocacy for her patients.
 
Her passion for travel and family life occupy her time outside of work and she joyfully shares her life with two dogs, one very entitled cat, and (yes, seven) tarantulas.
