The Happiness Gym is a joyous, experiential event based on the science of well-being. Participants take part in a curated theatrical experience, all throughout KDT’s new space, meant to boost their sense of happiness, joy, and feelings of connection. Support American Theatre: a just and thriving theatre ecology begins with information for all. Please join us in this mission by joining TCG, which entitles you to copies of our quarterly print magazine and helps support a long legacy of quality nonprofit arts journalism.
