Our Team:

Colleen Lee  /  Director

Colleen Lee is a singer and performer living in Evergreen, Colorado. She graduated from the University of Colorado with a degree in Literature and has enjoyed working with children of all ages for the past fifteen years. Along with performing on the stage in both musical theater and with her bands, she will be entering her fifth year as a youth theater director for the Evergreen Chorale’s Summer Music Camp program.

Trista Hertz  / Board President

Trista first dipped her toe into the theater world when her older son joined MYM’s cast of “Cinderella” in 2018 and she signed up to help with props for the show. After seeing the joy in the rehearsal process, as well as the creative fun of crafting a monster’s arm and a stack of wax-sealed invitations for the ball, she was hooked! Outside of helping behind the scenes at many local theaters, Trista enjoys art journaling, nature walks, and trips to Disney parks.

Susan's oldest daughter participated in the very first production, Tom Sawyer, 20 years ago when the organization sprouted through the vision of a couple of teachers wishing to give students an opportunity to express themselves through theater.  Witnessing the positive impact theater had on both of her children, she chose to get involved and support the amazing work that Mountain Youth Musicals does in this community.  She is currently heading up the SCFD grant writing effort.  After working most recently in the Jefferson County School District, she is now enjoying her retired life; golfing, swimming, and playing pickleball.
