Mona and Shara have been improvising for a combined 16 years. They met in college performing with the Stanford Improvisors and are now both ensemble members at San Francisco’s Un-Scripted Theater Company. In the summer of 2017, they toured the U.S. for 9 weeks performing and teaching improv in 19 cities.

Together, they teach a variety of classes and perform shortform and narrative lonform shows. In each show, you'll see them creating many different worlds, stories, and characters.

If I could give Mona and Shara six stars, I would. Characters, physicality, narrative, listening... all top-notch. They are both so likeable and watchable! Go see Mona and Shara do Improv!

Rebecca has performed in live and video sketch comedy (Crisis Hopkins and the Kasper Hauser Comedy Group) and an original solo performance (I Left My Heart in Brooklyn – The Marsh).

Rebecca teaches improv classes and workshops all over the place (mostly at BATS), acts in and writes various other projects, and is represented by agents who never book her any jobs. Most importantly, she has an awesome spotty dog named Pebbles. (YES, you can see a picture of her; just ask.)
