She got into the construction industry through an internship with Community Rebuilds, building a straw bale home in Moab. An Earthen Building course in Nicaragua led to some connections to the natural building community in CO. Being a tradesperson runs in the family: her grandfather designed and built houses in Florida. She is also on the board of the Natural Building Alliance. Most weekends, you’ll find Cheryl rock climbing, a hobby that has taken her to many beautiful places. https://images.squarespace-cdn.com/content/v1/5ac3c68055b02ce8b735f455/5bc54921-f66a-4af3-91d7-fdb6a9662c93/matt+e.png 2026 Board of Directors - Make it stand out Matt Ellsworth Matt is originally from Michigan and moved out to Colorado after graduating from Michigan State University in 2010. He started in construction at an early age, tinkering and building treehouses with his grandfather. Eventually, he moved into building climbing walls, which ultimately took him to Costa Rica to oversee construction of a climbing wall near Arenal. After returning to the US, he worked for several years on a non-profit backcountry trail crew during the warmer months, and climbed cell towers in the off-season. From there, he moved into commercial contracting and has since transitioned into custom homes. He is passionate about Green Building and seeks to help advance the shift towards more intelligently constructed homes that maximize comfort and longevity while minimizing waste and environmental impact. In his off time, Matt enjoys climbing, skiing, yoga, pickleball, and his adorable dog Alma. https://images.squarespace-cdn.com/content/v1/5ac3c68055b02ce8b735f455/23e62214-2dad-40e0-87ba-1b959ebc7980/Carrie.png 2026 Board of Directors - Make it stand out Carrie Larsen Carrie Larsen, the sole proprietor of August Design Studio, LLC, has over 20 years of architectural experience working in numerous sectors of the built environment, from large-scale commercial construction project management, to international and national commercial interiors, natural and alternative building methods, regenerative design practices, and residential architectural and interior design.
