A lifelong pursuit
Jason grew up in central Virginia with a Zebco in hand, chasing bass, bluegill and catfish. That childhood obsession became a lifelong pursuit, and for more than 30 years it has been done with a fly rod, in fresh and salt water.
Before guiding, he worked in the mountains as a backcountry guide and USFS backcountry ranger. He has guided the Smith, Missouri, South Fork Flathead, Jefferson, Big Hole and Rock Creek, and holds an M.S. in Environmental Studies from the University of Montana.
His guiding centers on education, conservation and an ethical approach to the freestone rivers of the Missoula Valley. Every client, whether they’ve never held a fly rod or have fished for forty years, leaves the boat knowing something new.

What clients say
Clients who keep coming back
Barry O. · Missoula, MT
Jason restored hope and joy
“He taught me casting, mending, managing my line, setting the hook, and landing fish. Despite the limitations in my life at the time, Jason restored hope and joy. Since then, I’ve had the pleasure of floating the Missouri, Bitterroot, Blackfoot, and Clark Fork with him.”
Preston B. · Alexandria, VA
Back several times a year
“His passion, skill, good company, and patience have drawn me, my family, and friends back to Montana to fish with him several times a year ever since. Cannot recommend him more — just don’t take my days!”
Gwen H. · Palm Beach, FL
A productive, enjoyable day
“His knowledge of the rivers is obvious the moment you step in the boat. If one approach is not working, he quickly switches things up — and it usually pays off. Plan on a productive and enjoyable day on the water.”
