Bob Drew

Founder and CEO

Bob’s passion for nature and water began during his formative years in Wisconsin, where he grew up in the water-abundant great lakes region. Along the way, he joined Kimberly Clark Corporation, where he spent five and a half years as an engineer in a California paper mill. Through his water management efforts he cut water usage whilst improving factory production and quality. The water savings generated of a million gallons a day is equivalent to the average water consumption of a town of 12,500 people.

In his career at Kimberly Clark, where he worked for more than 20 years, Bob held positions in Engineering and Research & Development (R&D) in the USA, Latin America, and Europe, managing large innovation and engineering projects.

Bob holds a degree in Chemical Engineering from University of Wisconsin and an MBA from UCLA. He speaks English and Spanish fluently.
