Dan Ruben is the Executive Director of Boston Green Tourism, an organization he founded to help hotels improve their environmental performance and lower costs. His career path was non-traditional, starting in healthcare administration before volunteering with environmental non-profits and eventually starting his own organization focused on greening Boston's tourism industry. As the head of BGT, he provides workshops, consulting services and technical assistance to help hotels reduce energy and waste usage and attract guests with their sustainability efforts. While running his own business is unpredictable, Ruben finds satisfaction and impact in spearheading the green hotel movement in Boston.
