Geoffrey Klotz, President and CEO of CEMS Experts has nearly 30 years of experience in the ambient and fixed source emissions monitoring industry. Using his educational background in electronics, engineering and industrial technology, he worked in various technical capacities over his 11 year career at Hewlett Packard. In 1989 he co-founded and helped grow the startup Altech Systems Corporation into a very successful CEMS integration company, which was sold to Waste Management. After the sale of Altech in 1992, Geoff founded his own CEMS integration and services organization GK Associates, which was rebranded to 'CEMS Experts' in 2011.
