Doak credits most of his accomplishments and success to golf course designer Pete Dye. Doak worked with Dye to learn how to construct golf courses during graduate school. Doak was exposed to several different schools of design on multiple continents in a variety of conditions. Jim Urbina taught him how to run a bulldozer allowing for Doak to think in three dimensions and how to use the materials around him.[1]
