ImprovBoston is a nonprofit improvisational theater, based in Cambridge, Massachusetts. It offers shows and classes its theater in Central Square. Classes are offered in improvisation, stand-up comedy, musical improv, and sketch writing. History Founding 1982–1993 In 1982, Ellen Holbrook, a former student at The Second City in Chicago and a producer of the Chicago Improv Olympic, moved to Boston with the idea to found an improvisational comedy troupe similar to Second City. Holbrook had the encouragement of former members of The Proposition, an earlier improv-comedy troupe, and Director David Shepherd, the founder of the Compass Players and the Improv Olympic. In the beginning, she assembled and trained several loosely knit bands of improvisers into teams that competed in the Boston "Improv Olympic" at Reilly's Beef and Pub near Government Center. Holbrook also arranged for David Shepherd and Second City's Michael Gellman to come to Boston to teach improv workshops to local performers. In 1983, Holbrook, along with Nicholas Emanuel and Katy Bolger, co-founded ImprovBoston, as the organization evolved. With their contacts, the group moved to Satch's near Copley Square, owned by former Boston Celtic Satch Sanders. In 1984, ImprovBoston officially became a not-for-profit corporation and moved to Ryles Jazz Club in Cambridge at Inman Square, where they remained for several years. Show formats varied but often included several improv games based on audience suggestions, set sketches based on improvs from past shows, musical improvs and song parodies. ImprovBoston troupe members often took turns directing shows, but other ImprovBoston directors during this time included David Thibodeaux, Jack O'Connor, Leslie Curtin and Brad Jones. 1993–2000 In 1993, under the leadership of Artistic Director Nancy Howland Walker, ImprovBoston acquired a lease to the Back Alley Theater in Inman Square - ImprovBoston's first dedicated theatre space. The ImprovBoston Mainstage cast performed late night weekend shows for several years, eventually expanding to prime time slots. Walker was just as instrumental in obtaining the New England franchise of Theatersports, which eventually became a regular Thursday night show at the theater. During Walker's tenure, the cast grew from five to well over 20 members. Larry Pizza became Artistic Director in 1995 and, in 1997, the artistic leadership again transferred, this time to Ron Jones, a former cast member from the early 1990s. It was under Jones' leadership that the theater began to extend its reach to further aspects of improvisation, creating new formats and shows beyond the
