Gertz-Ressler Academy High School Reviews

By on

We, here at 24th Street Theatre, LOVE the G/R students!  We've been working with Ms. Berkowitz's theatre classes this year and are so impressed with the talent of the G/R students!  We've been offering FREE tickets to the G/R students too and they seem to have a real appetite for the arts!   We work with literally hundreds of schools in L.A., but to have a long-term relationship with the school right across the street from us...priceless.
