Strengthened by community partnership, Treehouse Theater (THT) has been proactively supporting youth education and development through quality performing arts programming since 2012.  THT instruction with the guiding principles of respect, trust, leading by example, healthy communication, and teamwork produces students that can then strengthen the casts of arts organizations and their own public or private school theater programs.


In their first eight years, THT produced 23 high-quality local musical productions, won awards at seven of the past eight Junior Theater Festival national competitions, designed and built their first rehearsal studio on Franklin St, launched Acting Academy classes, hosted several specialty arts workshops, worked numerous fundraising events, and bought their own studio on Washington St.  Once limited to Manitowoc and Two Rivers, families now come from Valders, Sheboygan, Howards Grove, Brillion, Denmark, Green Bay, and beyond to participate in programming and join in the audiences.


Year-round operations are guided by the Board of Directors. Karen Rohrer, integral founder of the organization, serves as Executive Director and is the one full-time staff member.  Believing that youth will thrive from the opportunity to work with a variety of area arts enthusiasts, THT secures a fresh directing team for each musical. Interested students can choose to audition for the opportunity to appear onstage as cast members, apply as Jr. production team members, or volunteer to assist as members of the stage or technical crews. Each cast is a blend of new and returning student actors, all of whom are encouraged to explore their artistic individuality, be creative and responsible, improve their listening skills, and gain self-confidence while making new friends. Each cast and crew works together to develop a high-quality music theater production for sharing with the local community and/or showcasing at the Junior Theater Festival in Atlanta.


To further the mission of building confident leaders, Mrs. Rohrer partnered with volunteer Education Director, Deanne Stokes, to create and supervise the THT student leadership development program. When accepted as Jr. production team members, students between ages 14-18 can observe the organizational process and grow to appreciate the many challenges encountered during each production. Under the guidance of an adult mentor, some of these students have later stepped forward to lead one aspect of a THT summer musical. The 2019 summer production of Pirates Past Noon KIDS was proudly led by seven students in the positions of Director, Music Director, Choreographer, two Stage Managers, Set Designer/Decorator, and Hair Designer.


Each educational class and musical production serve to strengthen the extended community by attracting students from multiple public and private schools as well as from home school settings.  The December 2019 production of Disney’s ​FROZEN Jr featured 62 student actors who attend 27 different schools or are home schooled. Performances are held on the UWGB-Manitowoc Campus Theatre stage and audiences routinely fill nearly every available seat. THT takes great pride in exceeding the commonly low expectations for youth theater and audiences are repeatedly impressed by the high-quality sets, costumes, lighting, sound, and talent level of the student performers.



THT identified a highly visible, structurally-solid building and adjacent parking lot in downtown Manitowoc, in dire need of revitalization. The building, located at 910 Washington St, is 11,000 sq. ft. on two floors, plus a full, dry basement. The West Foundation awarded THT with a grant to fully fund the building's purchase in July of 2019.  The Executive Director designed a floor plan that focused on expanding future income streams, including a rentible 40’ x 50’ Community Room and 22’ x 25’ Kitchenette, one-on-one vocal and instrumental instruction rooms, and 1,200 sq ft Costume Room for storing all of our fabulous costume sets that are available for rent via the website This market is exploding as countless schools and community theater programs across the country face decreased funding and lack of staff needed for creating quality costumes for their youth musicals.


As of March 2021, 167 volunteers of all ages have donated over 4,600 hours on this project. Subcontractors are nearing completion of all new HVAC, electrical, and plumbing, working alongside skilled THT volunteers. This collaborative revitalization project will result in an exciting new permanent youth arts complex for many years of enjoyment by the extended community.

We are now nearing completion of all requirements ahead of full building occupancy inspection.  Once achieved, THT will schedule several small Open Houses, each with a limited number of guests, to see our amazing transformation of this renovation project.  Photos of the transformation can be found on our Facebook page.
