Jeff has been on the Committee for the Terra Nova Car Show and Swap Meet since its inception. This year, on May 20, 2023, the show will celebrate its 16th event, https://terranovacarshow.com/. Extremely popular, the event supports Terra Nova High School's Industrial Tech Program. Without it, the program is not possible. Along with showing cars, Jeff also provides the stage – one of his flatbed tow trucks.
Jeff, with a partner, also has a nonprofit – Auto Event Productions. They have been putting on the San Francisco Old Car Picnic in Golden Gate Park, since 2000. All the money made is donated to, and split between, San Francisco's Pomeroy Recreation & Rehabilitation Center—they provide recreational, vocational and educational opportunities for people with disabilities through programs and services that encourage self-expression, promote personal achievement, and lead to greater independence—and to Potrero Hill Family Resource Center.
The San Francisco Old Car Picnic happens in October.
