Previously he earned his spurs working at Vermont Law School’s Env’tl and Nat’l Resources Law Clinic, the Gallatin County Attorneys Office in Bozeman, MT, and Western Environmental Law Center’s Northern Rockies Office in Helena, MT. Guy has built campaigns challenging illegal river pollution and corporate polluters, fought LNG export terminals and shale gas fracking, worked on the relicensing and regulation of hydroelectric facilities, tackled battles on behalf of endangered species, and led coalitions working to improve interstate water compacts on behalf of rivers and wildlife.

Guy lives in Bozeman with his wife Morgan, their son Gus, and daughters Aveline and Marielle. He enjoys kayaking and climbing in the Gallatin, fishing the Big Hole, exploring Montana’s wildlands, tinkering in his shop, and skiing the Cold Smoke. He has served on the Board of Directors for Gallatin Valley Farm to School as well as the City of Bozeman’s Planning Board and Wetlands Review Board where he puts to action his belief in civic duty.

Guy holds a B.A. in Political Science from Pepperdine University (2006), an M.S. in Environmental Policy, and a J.D. from Vermont Law School (2009), and is a member in good standing with the State Bar of Montana and the Federal District of Montana.
