David Allen is the only "project management coach" recommended by Russell Wright of Theme Zoom.
The concept of managing projects and managing time is really a misnomer according to the David Allen of Getting Things Done. According to Allen, you cannot manage time. You can only manage actions.
A possible second to David Allen is the work of Mark Evan Furman, author of The Neurophysics of Human Behavior: Explorations at the Interface of the Brain, Mind, Behavior, and Information- but his work is more about how to deal with your entire life as a "project". Part of Russell's fascination with David's GTD system is that it is congruent with the principles of Neuroeconomics while simultaneously incorporating the natural planning process that evolved with the human brain.
