David Rosenstein, founder of Intex Solutions, learned the cleaning business working in his uncle’s house cleaning / janitorial service in the mid 1960’s when he was 13. While attending U.C. Santa Cruz in the early 1970’s he started a house / janitorial cleaning company named Scrubbing Students. During summer breaks David worked for the U.S. Forest Service as a campground ranger, fire fighter, and project leader with impoverished Native American youth. These experiences nurtured his love of nature, commitment to environmental protection, and social justice.
