Michael Somervillemichael somerville

Comedian, Host

When I first started standup comedy, the idea of standing in front of people was pretty intimidating. Moreover, with so many comedians in New York, just getting on stage was a challenge. That’s why I was thrilled to discover Stephen Rosenfield’s stand up comedy classes.


Michael made his late night debut on The Late Show with David Letterman. He has hosted shows for Nickelodeon, Encore, and Hallmark Channel and contributed to numerous publications from Time Magazine to Maxim. He appeared on NBC’s The Apprentice, Comedy Central, Bravo’s 100 Funniest Movies, History Channel and hosted Starz’s Stand Up or Shut Up, a miniseries about the ACI Stand Up Comedy Workshops.He headlines at Gotham Comedy Club and other major clubs across the country.

I started taking the comedy classes regularly, finding that I was getting more comfortable in front of audiences and was actually starting to accumulate material. I was starting to feel like a comedian. Stephen’s instruction is the most constructive I’ve seen. He doesn’t try to fit you into some preconceived notion of what comedy should be. He embraces who you are – be it an alternative performance artist or classic setup-punch comedian – and helps you find and hone your voice. Now that I am making my living in the business, I continue to use the standup comedy classes as as a place to try out new material. What takes weeks of stage time to create and refine, happens in a few days working with Stephen. For anyone from a beginner to an experienced comedian, I highly recommend Stephen’s stand up comedy class. In fact, I’ll probably see you there!”
