I've played a few of the course that he lists involvement in on his website: Broadlands, Coal Creek, Cordillera, Eagle-Vail, Flatirons, Foothills, Kennedy (Creek), Lone Tree, The Pinery, Raccoon Creek, Saddle Rock (wow maybe after listing them its more than a few).
It seems like a mix of original designs and renovation/consultation work. None of what I played really stands out as spectacular work, with probably two of my least favorite courses in the state on that list. I guess I haven't played his better work or newer stuff.
I do highly respect what he did at Kennedy (Creek nine) with a tough site and most likely a very meager budget. Definately a value pick.
