Chris Roussell, Concrete Busters of Louisiana, Bridge City, LA;
"Not only did Demolition Industry Consultants help us sharpen our estimating tools, we landed two considerable jobs with Bill's assistance. DIC has become a valuable resource for us in our estimating and day-to-day operations. When a special circumstance arises, we quickly get Bill on the phone. It's like having an extra estimator on our staff."

"We took the “Estimating Course for Demolition Contractors” and figured we got 20 years of experience in two short days. The handout materials are worth the price of the course alone."

Roland Savage, LVI Environmental, Las Vegas;
"Your common sense approach to estimating has helped me secure profitable demolition work and has kept me from the unprofitable. I live by the methods that you taught me, and those methods have helped me develop the thorough estimating habits that I pass on to other estimators under
my direction."

Tony Bodami, Titan Wrecking Company;
"Best move we have made. Our estimating capacity has improved three fold since DIC workshop commenced working with our organization. DIC has been very helpful and has provided outstanding results. Bill Gumbiner has no doubt been responsible for a tremendous improvement in our business. We thank you for helping Titan Wrecking and look forward to a long term relationship."

Chris Savoury "I was apprehensive in attending a seminar, with such “big fish”, after the first 10 minutes I was completely comfortable and excited to learn. What impressed me the most was the fact that all of you that have been in the industry for so long still had many questions. I would like to thank Bill, Marge and Bill’s son for what probably was one of the smarter things that I have done in my life. The Gumbiner’s are down to earth and truly a class act. “You folks are great! Thank you very much.”

Joel A Spirtas "I think that after attending one NDA convention after another, spending time with each of you was something that achieved a networking opportunity that does not often exist at larger and more impersonal conferences. Additionally, I am pleased to have had an opportunity to spend time with Bill Gumbiner, whose name is synonymous with the demolition industry in and around the U.S.

Chip S. Donewar "I would like to add my compliments, as well, to the Gumbiner family for the great presentation. I will admit I enjoyed the second day’s discussion about data and production. I thought that the comments and questions made were thoughtful and useful to many of us in the business. I am a newcomer to the business with only 24 years of experience and found the additional insight an opportunity to improve my bidding techniques.
