Call W. I. "Bill" Gumbiner - The Demolition Estimator Training Guy - and you will get 40-plus years of estimating, marketing and management experience. He is willing to pass on his knowledge of the demolition industry to owners, managers and estimators looking to shorten the mistake-ridden estimating and marketing "learning curve" in a two-day information-packed demolition estimating seminar. Plan to attend one of our seminars: April 30th & May 1st or Sept. 17th & 18th, 2009. Look forward to seeing you there.
