About Us Our History

Yellowstone Guide Training 2025
2018 to 2024
Guides of Jackson Hole or GoJH for short, was co-founded by Jackson locals Trevor Bloom and Charles Plummer III (aka Tres) in 2018. Trevor and Tres met in the cafeteria at Jackson Hole High School back in 2006, and have been friends and adventure partners ever since. We pride ourselves in being the only wildlife and naturalist guide company in Jackson founded by true Wyoming locals – and look forward to offering the finest custom-tailored experiences for anyone.

2024 Onwards
In 2024, as the work and family commitments that make life in one’s thirties a little fuller started to limit their capacity to operate the business, Trevor and Tres began the search for someone with the shared vision to take GoJH to the next level. That person ended up being Liam Robb O’Hagan, a Kiwi-expat with a background as a hiking guide on the Routeburn Track in New Zealand. Liam shares Trevor and Tres’ love of the outdoors and a dedication preserving it by educating visitors to wild places and enlisting them to the conservation cause.
