California's most recent award winner (1997). Performs on two stages and mounts an impressive selection of world, U.S. and regional premieres every season.
In the past 20 years, no less than ten plays (including Jersey Boys, Memphis and The Who's Tommy) have launched their path to Broadway success from La Jolla Playhouse stages, with seven of them winning Tony Awards and one garnering a Pulitzer Prize. They won their own Tony in 1993.
Yes, we know Oregon isn't in California, but it's so close to the border (and such an excellent company) that we just had to mention it. This repertory company performs far more than the word Shakespeare in its name suggests, with a wide variety of classic works and new ones. They got their Regional Tony in 1983.
As mimes, the winners of the 1987 Tony for Regional Theatre probably didn't have much to say. They don't have a permanent home stage, but instead take their performances to the streets, often appearing in local parks for free.
