Jeff co-founded Singletracks with his wife Leah in 1998 and has been dedicated to sharing the mountain bike information that inspires others to take epic adventures ever since. He started mountain biking in high school and served in the US Air Force before devoting himself full time to Singletracks in 2007.
Though formally educated as an engineer, Jeff began writing stories at an early stage, inspired by his mother who is a longtime accomplished author. He enjoys covering the world of mountain biking from every possible angle, whether it's trails or gear or skills. His goal for every story: that readers learn at least one new thing.
