David D’Beaupre grew up in western Montana and picked up a fly rod at the age of six. His early years were spent exploring the secluded, little-known waters of the Flathead Indian Reservation, where he lived. Weekends often meant road trips with his father to legendary Montana rivers, casting flies and honing the skills that would shape his future. By the age of twelve, David’s dedication paid off when he won the National Junior Fly Casting Championship in West Yellowstone, Montana.

At seventeen, David began guiding professionally on the Clark Fork River, where his father had pioneered one of the area’s first fly fishing lodges and guide services. The operation grew to include a guide training school, where David and his father taught countless aspiring anglers the art of professional guiding—a tradition that continues today, producing dozens of graduates each year.

Over the years, David has guided on waters across the Americas—from the Rio Grande and Pecos drainages of New Mexico to the Caribbean flats of Mexico and northern Belize. His adventures have also taken him to Chilean Patagonia, where he leads clients on weeklong summer expeditions in pursuit of massive trout in impossibly clear rivers—an experience he describes as some of the most exhilarating trout fishing on earth.

Beyond guiding, David has chased fish in Nicaragua, Belize, western Mexico, and offshore for sailfish and other pelagic species. He’s explored the coastal waters of Oregon and Washington, and traveled as far north as Canada’s Northwest Territories in search of walleye and northern pike.Known for his infectious enthusiasm, patience, and positive energy, David has built lifelong relationships with clients who return year after year to fish with him. A passionate fly fisherman for more than forty years, he has spent the last two decades guiding the year-round trout waters of California’s Sierra Nevada. And when he’s not guiding, you can bet he’s still on the water—fishing, traveling to fish, or scouting new spots to share with his clients.
