Events Crestmont Lives! For over 50 years, Crestmont Co-op School has been serving the East Bay and it’s families. We invite you this Saturday, January 26 from 2-4PM, to celebrate Crestmont past and Crestmont present. There will be activities and archives to share with all ages. This event is a great way to connect with our community and to learn why our small school inspires in a big way.
