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. They have done shows up-and-down the West Coast with Minerva and The Human Knot.


In 2016, Mona and Shara formed the duo Mona and Shara Do Improv. They enjoy exploring a variety of short and longform styles. This summer, you’ll find them on a 2-month tour across the country, performing and teaching in (at least) 20 different cities. Follow their trip on Twitter and Instagram @MSDImprov.

Guest Improvisers

We've had the opportunity to collaborate with the following fabulous guest improvisers! 

Dave Dennison has been improvising for almost as long as Shara and Mona have been alive. He teaches improv and performs with BATS Improv and Awkward Dinner Party.  He also does corporate training, coaches solo performers and acts in industrials, part of an ongoing commitment he’s made in support of capitalism. Go Capital!

Simon Pond has been improvising since the late 90s. He worked for a while for The Second City, performing improv and sketch comedy on the high seas onboard Norwegian Cruise Lines. He currently lives in SF (with his wife!)


Rebecca Poretsky began improvising with SIKO (Smith Improv Komedy Organization of Smith) at Smith College. In San Francisco, she regularly performs with the main stage company at BATS Improv and has also played with Speechless, Awkward Dinner Party, the Un-Scripted Theater Company, and Couples Therapy 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). She starred as Señorita Panochista in Spring Break: The Musical, a production written and produced by the Mortified team. Rebecca studied acting and improv at the Annoyance Theater in Chicago, the Flying Actor Studio, the Berkeley Rep School of Theatre, and Shakespeare & Company in Lenox, Mass.

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.)
