"At first I was a little apprehensive about spending 3 days learning about cleaning especially since I have been in the cleaning industry for 43 years! However, I went in with a very open mind and came out with a mind full of new knowledge and a completely new opinion and insight regarding Green Cleaning! 

At the end of the first day, I had knowledge I didn’t have before walking in. Dave opened up my mind and put in an abundance of positive thoughts and ideas not only on Green Cleaning but also different ways to market the concept and products related to a green program. By the end of the third day, I had sales copy for a project I am working on.  I say the following with no exceptions or reservations. All of your team members should go through Dave’s Master Certification class, as it will not only help in the sales of your ideas, operation and or program, but it will make them better staff members by having a better outlook on the future of the Jan/San industry!"

I personally am offering you a no questions asked guarantee, simply stating that you will find new and extremely valuable information about how to protect your health and the health of those who use the facilities you clean, on the very first day of the Master Green Technician class. If for some reason by the end of the first day, you do not feel you have found professional development education which will enhance your career and help you earn respect within your environment, simply fold up your workbook, hand in the passcodes, give me your address and you will receive a full enrollment refund, sent by check, direct to you.  Not one person has ever asked for their money back and I am sure you won't either.  David Thompson
