He has 4 courses ranked among the top 100 in the world according to the "Top 100 Courses in the World" list compiled by Golf Magazine.
These include Pacific Dunes in Oregon, Ballyneal in Colorado, Barnbougle Dunes in Tasmania and Cape Kidnappers in New Zealand.
Doak lives in Michigan.
He was a student of golf course designer Pete Dye, although perhaps his greatest influence comes from Alister MacKenzie (whom Doak wrote a book about), designer of Cypress Point, Royal Melbourne, and consultant to Bobby Jones at Augusta National.
In 2007, Doak restored Alister MacKenzie's home course, Pasatiempo, a Golf Magazine Top 100 course located in Santa Cruz, California.
Doak is the author of The Confidential Guide to Golf Courses which is a guide to famous and obscure golf courses around the world.
The original version of the book was intended for a select group of friends and golf course architects.
The sanitized version became a coffee table book which also included Doak's photography.
Despite being toned down, the book includes several extremely critical reviews of golf courses and alienated several well-regarded golf course architects.
For example, Doak's critique of Talamore Golf Club, in Pinehurst, designed by Rees Jones, made him "want to spit."
