Ms. Walker has been improvising for 2 decades, which is amazing since she’s only 22. The alumni wrote a show for Second City’s Vegas stage and traveled with their touring company. She improvised for four years with Boom Chicago in Amsterdam. You can catch Holly in the upcoming television series Go On with Matthew Perry and in the movie A Strange Brand of Happy with Shirley Jones due out in 2013. Not bad for a 22 year old.
