John Daviis, Conservation Director of the Adirondack Council, commented on Bob and his role as an "Evangelist for Old Growth":  "It was your contagious and charismatic enthusiasm for big and old trees in part, Bob, but also your commitment and dedication to wild forests, your powers of articulation in describing them, your sleuth-like ability to find them, and your moving sermons on their behalf!  In short, with respect to great trees and wild forests, you speak with authority.  You've a clear vision of how the East should be broadly and wildly forested, again some distant day."

The ENTS president is a certified arborist and former science technician with the GSMNP. Will has a widely recognized reputation as a tree measurer. He has been featured in articles, on TV., and on radio. Will is a co-author of "Stalking The Forest Monarchs - A Guide To Measuring Champion Trees". He has climbed and measured the tallest or among the tallest trees in South Carolina, Georgia, North Carolina, Tennessee, Pennsylvania, Massachusetts, and New Hampshire.

Will Blozan helped organized and mapped the structure of the Middleton Oak, in South Carolina, the Sag Branch Tulip - the first two tree to be mapped in eastern United States. Will organized and directed the Tsuga Search Project that documented the largest and greatest of the Eastern hemlock trees found anywhere, many of them hundreds of years old, prior to their untimely death as the result of infestation by an invasive insect - the Hemlock Wooly Adelgid. Will Blozan has recently become involved in a canopy mapping project of some of the giant Sequoia's in Whittaker Forest in California.
