Douglas’s journey at Ecolab began in 1989, when he joined from Procter & Gamble and quickly advanced through leadership roles in marketing and operations across North America and Europe. As President & COO (2002-2004), he built a foundation of discipline and strategic clarity before taking the helm as CEO. Under his leadership, Ecolab executed targeted, high-impact acquisitions, embedded digital and sustainability-led innovation, and earned accolades such as the 2018 Deming Cup for Operational Excellence.

Post-Ecolab, he founded E2SG Partners (2022), an investment firm focused on environmentally sustainable growth.

• Corporate governance – leading boards of public companies and institutions on strategy, risk and stakeholder trust

• Sustainable investment & ESG leadership – fusing purpose-led investment with operational and governance impact

A graduate of the College of the Holy Cross and former P&G marketer, Douglas is respected for combining business discipline with environmental and social purpose.
