This approach will have success in hooking and landing fish all while experiencing the “WOW FACTOR”!

Christopher Weber

Christopher caught his first fish at age two and never looked back. Growing up in Wisconsin meant a lot of fishing for Christopher. Family vacations all revolved around fishing and he followed his father to the water every chance he got. Living on Wisconsin lakes made access easy and the sport never grew old for Christopher. Moving to Colorado in 2001, he sought to expand on his fly fishing, including tail-waters, creeks, lakes, warm water systems and high mountain adventure; he loves it all. Fishing with either kids or adults, he believes nothing is better than fishing, except sharing the experience. And with 200 days a year spent on the water he has some sharing to do!

Duane has guided all major streams, rivers and lakes on the eastern slope of the Rocky Mountain National Park, as well as hiked nearly every trail and backcountry area.
