Owner, Northwest Trails

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. Trail work has been his profession and passion ever since. In his first ten years in business, he had the good fortune of being able to work under several very dedicated seasoned career veterans in trails, learning the rich variety of skills necessary to be successful in this highly competitive industry.

Gerry has an extensive background in planning, designing, estimating and developing trails, bridges and greenways for local, state and federal governments, as well as private developers. 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. In over forty years in the business he has served as project manager for several hundred projects while designing and drafting contracts for more than one hundred of them. He has managed or participated in numerous multidisciplinary project teams. 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. He has participated in all forms of trail based recreation and is particularly nuts about skiing, sailing and scuba diving - - or wherever his next outdoor adventure will take him.
