About David Keller

I have spent 27 years in upper management with three Fortune 50 companies and over 20 years as an entrepreneur. During the latter, I have started up and owned several companies. I am now focused on my passion, clean air and clean water for the world. According to the EPA, 55% of all US streams, lakes, and ponds are contaminated, and over 50% of drinking water does not meet EPA standards. Precision e8 can sanitize and disinfect the air we breathe, the surfaces we touch, and the water we drink. I co-founded Precision e8, a company that specializes in developing innovative technologies for cleaning air and water without any negative environmental impact. Our non-toxic oxidation processes have been successfully tested, and we have filed provisional patents for our technology. With everything in place, we are now ready to scale up and launch our business nationwide.Using all my previous experiences and developed skills, we are creating an organization that will manufacture, sell, and market our systems to industry segments throughout the US and Canada. We will then reach out to the international market. Stay tuned for my updates. We’re going to make a huge splash in the clean water and clean air business, making the world environment a safer place to live.

Listed skills include New Business Development, Private Equity, Strategic Planning, Venture Capital, and 44 others.
