Fatima Z.Veterinary Assistant
Fatima moved to San Francisco from El Salvador at the age of 11 years old. Her passion for animals began as a child, where she witnessed her uncle caring for stray animals in El Salvador by providing food and shelter. Her uncle would also take care of all the injured animals. Through witnessing and helping her uncle, she too started caring and providing shelter for the stray animals. The animals returned the love by gathering around Fatima's house to protect them and to also call a place home.
This passion transcended into Fatima’s teenage years, where she volunteered at the San Francisco zoo and educated others about the animals at the zoo. When the time came to choose a major, Animal Science was the obvious choice. Fatima graduated from California State Polytechnic University, Pomona with a B.S. in Animal Science. During her time at Cal Poly Pomona, she worked with sheep, goats, pigs, and rabbits. She helped by socializing the animals, restraining for medication administration, and working side by side with onsite veterinarians to ensure the best health of all the animals.
Fatima became a part of the Blue Cross Pet Hospital family in 2020. She honed in her administrative skills in reception and now uses her clinical skills as a veterinary assistant. She continuously strives to provide the best care for your lovely fur children! She is also a huge fan of Chihuahuas as she is the mom of two of her own, Dante and Mustard
