Charles Dundas..."Charlie" began building trail, as a volunteer in 1958, while a Boy Scout. His company, Tri-State Company, has been building trail, professionally, since 1987. Tri-State's market niche is remote site construction, often employing helicopter support. In the course of 24 years, they have built, designed, reconstructed or maintained over 500 miles of trail. They are, perhaps, better known as the "bridge people", having built numerous bridges to include: cable suspension, glu-lam, steel, heavy timber, and their specialty, unique curvilinear screw laminated bridges/elevated walkways. Charlie views his company as more than a trail building company, he sees it as engaged in the art of "recreational infrastructure".

At the age of two, Gerry’s parents started taking him on mountain hikes and fishing trips. In 1972, as a way to put himself through college, Gerry began his professional trail career by bidding on trail maintenance contracts in the rugged North Cascades Mountains.

He has received national & regional awards for his work and has a widespread reputation for innovative solutions in creating low-impact trails through wilderness and natural areas.

Many of his projects have involved large budgets, challenging schedules, complex and remote structures, or other tricky design and construction issues.
Since 1990, he has taught many training classes and workshop sessions on designing, contract drafting, managing, maintaining and building quality, sustainable trails and systems. From 2004 to 2007, he served as President of the Professional Trailbuilders Association, and he currently sits on the board. When not working, Gerry enjoys spending time with his family outside.
