William Hall

William is an actor, director, trainer and mask maker. 

In 1986 his friend Rebecca Stockley said, “I’ve written a cool story, guess what it’s about?”  After about 10 minuets William had guessed the whole story.  When she revealed that he had written the story with his guesses…William’s life changed.  He realized that there were stories in all of us and that storytelling could be effortless.

He worked with a few brave folks in San Francisco and started BATS Improv.  Today BAT Improv is a thriving improv community with a 200-seat theatre, a full-time staff and a spirit of growth and exploration that make it a great place for actors, students and audiences.

He’s performed and taught improv all over the world and even directed The Life Game© in Lodz, Poland.  He has been in a few movies, TV shows and commercials.

His company Fratelli Bologna designs and delivers improvisational based training.  Fratelli Bologna helps people use the power of theater to tell their stories through trade shows, training and conference
