About Us

Bennett and Williams Veterinary Corporation purchased San Marin Animal Hospital in the early part of May 2015. It is a 2-veterinarian partnership that began as a friendship in 2002. Dr. Jeff Williams met Dr. Erin Bennett when she worked for him as a technician in a southern Marin vet hospital. As fate would have it, Williams inspired Bennett to become a veterinarian.  After all these years, they finally joined forces. Luckily, a third veterinarian, Dr. Sarah Reardon, believed in their vision and graciously agreed to join their team at San Marin Animal Hospital.


Dr. Erin Bennett, DVM Practice Owner

Dr. Erin Bennett grew up in Terra Linda, attended Marin Catholic High School, and graduated from the University Of Colorado at Boulder. She spent many years facilitating veterinarians, one of which was Dr. Jeff Williams, before deciding to go to vet school herself in 2003. After spending the next 5 years at University College of Veterinary Medicine Dublin in Dublin, Ireland, she worked as a vet in Dublin for 3 and ½ more years, married her husband and moved back to California in 2011. After working as Chief Of Public Medicine at Sonoma Humane Society for 3 years, she decided to join San Marin Animal Hospital in 2014 and has been here since. She and her husband and their 2 little kids live in Sonoma County, with 7 cats, 3 dogs and 3 goats, 2 sheep and the list continues to grow. In her spare time…well, she cleans up after her toddlers.


Dr. Jeff Williams, DVM Practice Owner

Dr. Jeff Williams was born and raised in Fairfield, CT and graduated from Wesleyan University in Middletown, CT in 1984 and Tufts University of Veterinary Medicine in Grafton, MA in 1990. He worked in private practice in Derry, NH after graduation until moving to Marin County in 1993. He was in private practice in San Rafael and Larkspur. While there, he met Dr. Bennett 10 years before accepting the job as Veterinary Medical Director at Guide Dogs for the Blind, Inc. in 2003. He lived in Novato for 8 years before moving to Woodacre with his wife and 5 year old son. They have a rescue dog named Amigo, Mr. Jones the cat and two chickens. He is an avid mountain biker, hiker and gardener.


Dr. Sarah Reardon, DVM Associate Veterinarian

Dr. Sarah Reardon was born in Atlanta and then moved to New England where she lived during her teenage years. She attended the University of Southern Maine where she received her pre-medical degree. In 2008, she married her husband, Keegan, and they moved to California to further her dream of going to veterinary school at Davis. In 2014, that dream came true when she graduated from UC Davis and joined the San Marin Team in the summer of 2014. In her spare time, she loves hiking, gardening, painting as well as doing Pit-Bull rehab and rescue. She recently added a son named Theodore to the family. She is owned by 4 dogs, 5 cats and 4 birds- it’s a zoo in here!

Samantha Wilson, Veterinary Assistant 

Samantha has been in the veterinary field for the past three years. She is currently enrolled in the Veterinary Technician Program through the Santa Rosa Junior College. Her love for animals started when she was a little girl collecting stuffed animals and reading dog books. She plans on continuing her career in small animal medicine and extending it to large animals in the future. San Marin Animal Hospital is full of amazing veterinarians and staff; I couldn’t ask for a better team to learn and grow with!

Her interests in the field are behavior/training, dental cleanings, and small animal nutrition.

Serena Cole, Customer Service Representative

Serena was born and raised in Sonoma County where she has worked in the Veterinary Field for the past 10 years. As a little girl, she couldn’t imagine doing anything other than working with animals when she grew up. She has a sweet dog named Duke and quite a few cats that keep her busy!!
