 is a vibrant and challenging play that explores the elusiveness of truth on a variety of levels. On one side, a groundbreaking proof about prime numbers whose authorship is in question. On the other side, the central character, Catherine, who has been caring for her father who has mental health issues, but now must transition to caring for herself.  She faces tremendous challenges with family, love, the future, and confronting her own mental health questions.

Setting: The back porch of a house in Chicago, IL.

PROOF is presented by special arrangement with Dramatists Play Service, Inc., New York. Originally produced by Manhattan Theatre Club on May 23, 2000. Subsequently produced on Broadway by Manhattan Theatre Club (Lynne Meadow, Artistic Director; Barry Grove, Executive Producer) Roger Berlind, Carole Shorenstein Hays, Jujamcyn Theatres, Ostar Enterprises, Daryl Roth, and Stuart Thompson on October 24, 2000.

From the Director

Looking forward to the spring semester, we are very hopeful audiences will be back in the theatre for live performances!

Charitable contributions help to sustain our program especially during economic downturns like what we have experienced during the pandemic. While ticket sales have been impacted, we are grateful to continue offering amazing virtual performances, some of which were offered free to the public.  We continue to look to you, our audience, donors, and subscribers, to provide additional support and help us continue the quality productions that COM is known for.  

Our 2021-22 season will move forward this spring with As You Like It as well as two amazing Studio theatre productions soon to be announced! 

I look forward to the time when we can all be together again.  When I can see you in the lobby, catch up on your activities during the pandemic, and share a live stage experience that will be both uplifting and meaningful.

Thank you for supporting the College of Marin as well as the students, faculty, and staff who work hard every day to safely bring the college and community together.

I’ll see you soon at the James Dunn Theatre!
