Kyle Stack


Kyle pursues his love of fly-fishing on the Poudre River during his summer vacations away from the middle school where he is an administrator. His passion for every aspect of fly-fishing, from tying flies, to reading water, to river entomology, and enjoying the tranquility of the Poudre Canyon, informs his guiding and helps define his way of life. Kyle has explored and fished numerous rivers around Colorado, Wyoming, Montana, and New Mexico, although he is always called back to his favorite river, the Poudre. Kyle is a natural and encouraging teacher and enjoys sharing all aspects of fishing and the river with clients. This is his sixth season as a guide and teacher of St. Pete’s Signature Fly Fishing Class. A day on the river with Kyle is a great introduction for the first timer or a fine tuning for the accomplished angler.

Joel DeJong


A high school English teacher by trade, Joel is currently a graduate student at Colorado State University. Beginning in 2009, Joel was able to combine his passion for fly fishing with his love of teaching by way of guiding for St. Peter's. "The best thing about guiding," Joel reflects, "is the privilege of seeing that distinctive and dazzling smile that folks tend to sport when they land their first trout on a fly. It never gets old." Equipped with a solid sense of humor and an inherent enthusiasm for teaching, Joel is an excellent guide for anglers of all skill levels.

John "JB" Bruning


John (JB) Bruning is a third generation native of Colorado who has fly fished the Colorado streams and lakes for the past 50 years. Now guiding in his fourth year for St. Peter’s Fly Shop, JB enjoys teaching first-timers as well as helping experienced fly fishers improve and learn new skills, such as, European nymphing and English still water techniques. For JB, a great day on the water with his clients is having fun, learning and building relationships in the beautiful settings where trout live. When he’s not guiding, fly fishing or skiing, JB is a metal sculptor working in his studio located in Longmont, Colorado.

Jason Small

Jason started chasing trout as a young child in the Midwest before moving to beautiful Colorado over 20 years ago, Jason has pursued his love for fly fishing all over Colorado and New Mexico. He spent 8 years pursuing the elusive trout in the high mountain streams and gold medal waters of southwest Colorado before moving to Fort Collins 5 years ago. Jason now finds his home here on the banks of the Poudre River and many other local watersheds.

A day on the water with Jason is all about having fun and learning the skills to be a great angler. Jason's easy going personality and love for fly fishing is the perfect match for anglers of all skill level.

In his free time, Jason continues his passion for all things fly fishing, including teaching his young daughter Norah how to "spot risers" and tie the perfect fly. When Jason is not on the water he enjoys time with his family in the great outdoors; camping, hiking and enjoying nature.

Rex Monahan


A favorite saying of Rex's is "the only constant in life is change" while that may be true most the time, fly fishing has been a constant in Rex's life for a long time. He started out with an old Sears Roebuck bamboo rod, a Orvis clearwater reel and a few Adam's no. 12s on the Poudre and quickly fell in love with the sport. A Colorado native born in Sterling, he's spent most of his adult life moving either literally or figuratively closer to the rivers he loves to fish. He migrated from Sterling, then to Greeley and eventually ended up Fort Collins about 4 years ago. Eventually, with a drive for new adventure and challenge his love for fly fishing manifested itself into guiding. This is where he found the "next level" fishing experience. Guiding others provides what was described to him by another guide as "an out of body fishing experience". That along with the joy he has in teaching others the craft of fly fishing as well as being privileged to take part in the experience of the outdoors and adventure with those he guides makes for a pretty good bet that not only fly fishing, but guiding also, will be a constant in his life for a long time to come.
