Jeff Kish has hiked both the Pacific Crest Trail (PCT) and the Pacific Northwest Trail (PNT) and now works for the PNT. After hiking the PCT he became an immediate advocate, trying to help other hikers and future hikers alike. As son as he finished his thru hike of the PNT, he did the exact same thing! 

This passion took him all the way to now working for the PNT and helping the trail itself. His talk about the Washington section of the trail has inspired me to start section hiking the trail.
