The Dedham Community House is a non-profit association that was founded in 1922. It serves to preserve the historic mansion it is housed in, and to provide a recreational center for the people of Dedham and the vicinity.

Although members can join as individuals or families, non-members can take advantage of everything the Community House offers for the town such as, pool access, martial arts pilates, and even a pre-school. The Community House also features access to the Charles River, athletic fields, and an event hall - all for community and member use.
