Nutrition Staff


Dr. Lisa Weeth, DVM, DACVN®, Head of Nutrition Department

Dr. Weeth received her veterinary degree from the University of California, Davis, in 2002. After two years in general and emergency practice, she returned to UC Davis in 2004 for a Residency in Clinical Nutrition. She completed her training in 2007, became a Diplomate of the American College of Veterinary Nutrition (ACVN), packed up her family and moved from the west coast to the east coast. There she established the first dedicated Clinical Nutrition Department in a private practice setting at Red Bank Veterinary Hospital in Tinton Fall, NJ. Dr. Weeth provided nutritional support to veterinarians and pet owners in the greater New Jersey/New York area until January 2014, when she and her family (including the 3 cats) once again packed up and moved, this time to the United Kingdom. While living overseas she started Weeth Nutrition Services, a veterinary referral service that provided nutrition telemedicine to veterinarians and technical support to members of the pet food industry. In August 2016 she and her family moved back to California and Dr. Weeth was able to expand her telemedicine service to offer in-person appointments to patients and their caregivers in Los Angeles and the surrounding areas.

In her free time Dr. Weeth enjoys spending time with her family, exploring new parks and walks with her rescue dog Penny, and traveling to new and interesting places. Dr. Weeth loves all things food and food-related from growing the ingredients in her garden to putting them together in delicious ways for her friends and family.
