I have fished with Chad for over 10 years now and I look forward to hanging out and exploring new water with him every year. He is very knowledgeable, always prepared, enjoyable on the river and super organized when it comes to executing his trips. I would highly recommend fishing with Chad any time you have the chance!!!!

Our fly fishing group has used Chad Olsen and GYFO for the past ten years and have never been disappointed. He instructs without being overbearing, knows the rivers of Montana and Wyoming well, and consistently puts our group on fish. His knowledge of each river is extensive and often finds fish when other nearby outfitters are watching in awe. His ability to teach fly fishing techniques and fundamentals during the fishing day has made us all better fishermen. His sense of humor and his gentle reminders to "center up" on the boat and to "set the hook" (!!) make for a fun day on the water. He's by far the best guide/outfitter I've used in over 30 years of fly fishing. Our group of 6-10 fly fishermen have used him exclusively for the last ten years when we venture out of Colorado! Any day on the river is good -- but a day with Chad makes it exceptional!! He's more than a fishing guide to us -- he's become a good friend as well!
