climate crisis head on. Dave’s background is rooted in community organizing, people-first
streets advocacy, and community mental health.
Dave has been one of the principal organizers for the Richmond Family Transportation Network

older adults, and people with a disability.

Throughout his work on those projects, he realized the importance of SF Bike Coalition’s members and was inspired by their tireless efforts towards advocating for project approvals.
