COTA Staff & Board
Meet the people behind the mission
COTA is powered by a small but mighty team of five staff, funded through a combination of grants and generous public support. COTA’s Board of Directors and Chapter Representatives — while all volunteer positions — work equally hard and are the backbone of the organization, providing vital visionary leadership and boots-on-the-ground support. Their responsibilities range from strategic planning and fundraising to social media management and community outreach. They’re a talented and dedicated bunch, and COTA wouldn’t be the same without them.

Crisp Flagline mornings, long Mrazek miles, flowy mountain singletrack, and the hum of tires on dirt aren't just hobbies for Truett, they're part of his DNA. COTA trails have been his classroom, therapy office, church, and proving ground, especially after earning not one, but two titanium shoulders!
Originally from Arkansas, with roots in Bentonville "MTB Capital of the World" (hahaha), Truett has spent the last three decades riding trails across Arkansas, Colorado, and for the past nine years, his favorite here in Central Oregon. Some PNW folks still say Truett has an accent, but he doesn't believe them.
After a long career in teaching and pastoring, Truett leads the Jefferson County Faith Based Network as their CEO in Madras, Oregon, helping bring hope, support, and free resources to those experiencing extreme poverty in Jefferson County Oregon.
