Greasy Creek Outfitters was started in 1997 by Mike Smith, who at first fished the New River for his own enjoyment, later bringing friends along who spread the word to their friends and lead to the birth of 'Greasy Creek Outfitters.' In 2006, Darin 'Gil' Gillenwater joined Mike in the GCO venture as a guide with a lifetime of fishing and outdoor experience. When Mike started New River Fly Fishing in 2009, it created the opportunity for Gil to own and operate the company he loved while still keeping a professional relationship with Mike while cross-promoting both ventures. Today, Greasy Creek Outfitters is owned by Gil and Kelly Gillenwater and continues to operate just as it did under Mike Smith.
