Berkeley Parents Network (BPN) is an online nonprofit network for parents who live in the San Francisco Bay Area. BPN was founded in 1993 as an email list for student parents at University of California, Berkeley and has grown by word of mouth to include more than 40,000 subscribers from all over the Bay Area. Parents use BPN to exchange advice and recommendations with other parents, and find childcare, schools, camps, and classes. It is free for local parents to subscribe. BPN also accepts paid Community Subscriptions from schools, camps, childcare providers, and other kid-related services that want to publicize their programs on BPN.
