Thank you for your donation this holiday season!

It takes a village to sustain the Children’s Museum of Sonoma County and help instill a love of learning in the youngest members of our community through their engagement in our dynamic exhibits and programs. Admission and membership fees don’t fully cover the cost of operating the museum. Our Access for All program—which offers all families, regardless of financial circumstances, the opportunity to visit the Children’s Museum—relies on support from friends like you and our community. 

Your generosity today will help the Children’s Museum continue to inspire curiosity and creativity through joyful, transformative experiences. Thank you.

It’s Time to Expand the Place Where Wonder Begins

The Children’s Museum is proud to announce the launch of the Unlock Potential! (UP!) Campaign — a call to action and an investment in the future of our community and its most precious resource: children.

As part of this exciting next chapter, the Museum plans to break ground on a major expansion in August 2026, with a grand opening slated for Spring 2028.

Support at any level makes a difference.
