Dr. Le-Nguyen

TREAT Veterinary Surgery Service specialized surgeries

“Compassionate & Gold Standard of Care”
Dr. Le-Nguyen graduated from UC Davis School of Veterinary Medicine. He completed an undergraduate degree in Biological Sciences at UC Davis. Being a general practitioner at local veterinary hospitals, over the years, Dr. Le-Nguyen acquired a special interest in dentistry, soft tissue and orthopedic surgeries.

Upon seeing pets not being able to get the surgeries they need due to pet owner financial constraints, Dr. Le-Nguyen sets out to receive advanced continued education and surgery training. He participates and collaborates with other surgeons and colleagues to hone in on these surgical skills–using the most up to date techniques and standards.

Today, Dr. Le-Nguyen is a veterinarian who is able to provide his surgery services not only in Sacramento, but in surrounding cities. He is able to offer these surgeries to pet owners and local shelters who would otherwise be unable to afford these surprise emergency and complex surgery costs. Pets are getting the treatments they need to live healthier lives and shelter pets are given a second chance to find a new home.

Siena Garcia

Technician Assistant

Hi there! I’m Siena. I have been working in Vet Medicine for 5 years now. But about two years ago I became a technician assistant and found what I’m meant to be doing. Having grown up in our family-owned pet store, my love of caring for animals started very young. Nothing makes me happier than being able to play a part in helping care for your pets. I can not wait to meet you, and your furry family member at your next visit! I have a border collie named Avery who I enjoy spending my free time with. As well as gardening, going to the gym, and experimenting with all things makeup or nails related.
