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.

Thanks again for everything. It was easily the best trip ever! Your patience and skill with Will was very impressive. I had hoped that you would make a fisherman out of him and you exceeded my expectations. The effort you put in for us day in and day out was phenomenal!
