Bringing the Funny Since 1984

CSz Boston is locally owned and operated. We're also part of CSz Worldwide, a global network of companies that transform the world using improvisation. Through our unique ability to foster collaboration, inspiration, gratitude and fun, we've since grown to have presence in 27+ US and European Cities.

The CSz Difference

Because CSz Worldwide is stocked with professional managers, players and teachers in 27+ cities, this means we're widely available to clients and fans anywhere. With 34+ years of history (many of us have been with CSz for 10, 20, even 30 years), we've got the experience. CSz has over 600 trained professional players and dozens of instructors active right now - we have a deep bench.
