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.
