Emmeline is an Associate Veterinarian at Petsadena Animal Hospital, brings a wealth of knowledge, dedication, and compassion to her role. Born and raised in San Diego, Emmeline pursued her undergraduate studies at the University of California, San Diego (UCSD), where she majored in Biology and minored in Economics. After graduating in 2015, she gained invaluable experience working at various veterinary clinics in San Diego while applying to veterinary school. Her academic journey led her to Midwestern University in Arizona, where she earned her Doctor of Veterinary Medicine degree in May 2020.
During the pandemic, Emmeline took time off for health and safety reasons but began her professional career in the Greater Los Angeles and San Gabriel Valley areas in October 2020.

Realizing her lack of passion for economics, she decided to pursue a career that would allow her to make a meaningful difference in the lives of animals and their owners.
Emmeline’s passion for veterinary medicine was inspired by her first dog, Coco, a chihuahua mix she adopted at 16. Her drive to provide Coco with a happier, healthier life sparked her interest in becoming a veterinarian. A defining moment in her career was managing Coco’s malignant cancer during veterinary school, which involved collaborating with specialists and ultimately extending Coco’s life by two years. This experience solidified Emmeline’s commitment to helping other pets as those specialists helped hers.
In her practice, Emmeline finds great joy in the honesty and resilience of animals. She values their straightforward nature and the lessons they impart through their genuine behavior, even in the face of illness or pain.

She enjoys playing video games, online shopping, and attending conventions and fairs. Fluent in Mandarin Chinese, Emmeline brings a diverse set of skills and experiences to her role at Petsadena Animal Hospital, where she continues to make a positive impact on the lives of her patients and their owners.

For Dr. Fred Li, the veterinary profession encompassed four strong passions of his including science, medicine, teaching, and of course animals!
He is proud to serve a passionate population of people that want to do what they can to take care of their animal companions. “Animals often cannot communicate what is causing them pain or discomfort,” Says Dr. Li. “So as a veterinarian, my knowledge and skills allow me to try to get to the source of the issue and provide relief for both the pet and their caring owners.”
As a dedicated veterinarian, Dr. Li is also a proud pet parent. He has two dogs, including a sweet and energetic poodle terrier mix named Indy (after Indiana Jones due to her adventurous nature), and a recently adopted miniature poodle puppy named Hazel (due to her chocolate-colored coat).
Outside of work, Dr. Li enjoys exploring new places both locally and around the world. He also has a passion for astronomy and is starting to learn astrophotography. Learning new skills is another enjoyable pastime of Dr. Li’s, whether it is constructing a shelf from scratch or learning to fix things around the home.
A fun fact about Dr. Li – he once successfully performed CPR on one of his pet turtles! Of the experience, Dr. Li says, “This was when he was still an undergrad. Charlie, my red ear slider, had managed to knock off the filter cover and, as a result, his leg got caught. When I found him, it looked like he had drowned. I rushed to get him unstuck. Then, with the amazing power of Google, I found a guide on how to perform “CPR” on a turtle. Thankfully it did not involve giving mouth-to-mouth, but rather placing him on a downward slope and moving his front legs to expand and contract his lungs. Miraculously, he survived and made a full recovery!”
Dr. Li is very excited to have the opportunity to serve the clients and their precious pets at Petsadena!
