Eric was born and raised in Soda Springs, Idaho. He began fly-fishing around 6 years old when his mother taught him while growing up in southeast Idaho. Eric attended college at Montana State University, where he earned a degree in Biotechnology. His enthusiasm for fishing continued throughout college and eventually landed him at Three Rivers Ranch where he began guiding in 2003. ‘There’s a great camaraderie at the Ranch. Lonnie is great to work for and the guides are not only co-workers but also friends. We often take off and fish together when we have free time or during the off-season. I grew up fishing the South Fork of the Snake River and love those lower stretches, but I must say the lower Henry’s Fork is awesome because of the size and quality of the fish.’ Eric lives in Ashton, Idaho.
