I’ve been fishing with Chad at GYFO for at least 20 years. He knows how to put you on fish in any kind of weather on any river. A great guide and a great guy!Rush Benton

I have been a client of GYFO’s owner, Chad Olsen, for over 20 years. Whether you are fishing in Montana or international destinations, GYFO always delivers. I look forward to adding Thermopolis, Wyoming, to the many places we have fished together this summer.George Stewart
