Having Fun

BIG connects with its performers, students, and audience to share in the energy and spirit of having fun.


Baltimore Improv Group (BIG) is celebrating its 13th Season of bringing comedy to the Greater Baltimore area. We began in the traditional manner for Comedy theaters. In 2004, the Navy transferred Mike Subelsky from San Diego to Maryland, and after biking around town, putting up flyers, a robust 4 people became the first members of the Baltimore Improv Group. That old story. In the decade since, BIG has grown to 60 performers, and, since October 2016, we have been in residence at the Single Carrot Theatre in Remington.


BIG performs over 120 times per year in Baltimore City and the surrounding area. These performances include our regular mainstage shows, shows for organizations from Bank of America to Johns Hopkins, and for private clients from bachlorette parties to bar mitzvahs. Since 2007 BIG has hosted the annual Baltimore Improv Festival. In an average year, BIG performs for over 5000 people.


BIG teaches Six sessions of Seven week Improv Classes for adults each year, as well as classes and workshops for kids and teens, and an Annual Improv Summer camp. We are in our third year as resident artists with Young Audiences of Maryland (YAMD). With YAMD, we perform in assemblies and teach residencies in schools across Maryland.
