Nancy Kerson
ASAR (Animal Search And Rescue) Co-Lead
Napa CART Advisory Board Member
From early childhood, animals of all kinds have played a big role in Nancy’s life. As a child, when people asked her what she wanted to do when she grew up, the answer was simple: live in the country surrounded by animals! (It was only much later that she realized this question was actually about making money…)
After graduating from the University of New Mexico in 1970, Nancy taught school on a remote island in Alaska before marrying Michael Kerson and coming back to the “lower 48.” In 1972, the two, along with Mike’s parents and another man, founded Vine Village, Inc. a 501c3 program for people with developmental disabilities, which they continuously directed until retiring in 2023.
Nancy adopted her first Mustang, Sparky, in 2001. Nancy and Mike both have gentled and halter-trained several wild horses for the BLM adoption program, and their own personal herd now numbers 5 mustangs, a mustang mule, a BLM burro, and a mammoth saddle donkey. They also have a dog, 3 cats, and a flock of chickens.
Nancy has been active in Napa CART from the beginning, and was active in Napa CART’s response efforts during the 2017 and 2020 wildfires, as well as mutual aid for the 2018 Camp Fire and 2019 Kincade Fire. Currently she serves as ASAR Co-Leader.
