I've fished with Chad and GYFO every year since 2000 on many of the rivers in the Greater Yellowstone area.  We've fished solo and on group outings I have sponsored for friends and clients with multiple boats with his very capable guides.  Astute guides and teachers, they even helped teach my kids to cast a fly line many years ago.  I keep coming back because Chad always makes the extra effort to make each trip rewarding.

My family and I have used Chad Olsen as our fishing guide in Montana and Wyoming, for over 20 Years. I can say without hesitation that he has provided me and my family with marvelous fly fishing experiences.  He is extremely knowledgeable, honest, and hard working.  He has also become a friend whom I treasure.
