Mark’s professional career spans more than three decades as a healthcare administrator, lawyer, government advisor and business leader. He founded Hospital Energy (now Environ) in 1995 to provide lower-cost, clean-energy sources for healthcare institutions. Hospital Energy transformed into Environ in 2021, and Mark serves as CEO for the private equity-backed energy firm.
In the United States, Mark has been a tireless champion of ground-breaking approaches to energy and environmental management. As an attorney, he has been at the forefront of developing federal and state laws, regulations and industry standards that improve human health and the environment. As a business leader, he has forged some of America’s largest and most successful healthcare energy aggregations and used their negotiating power to create several major innovations in how hospitals procure and manage energy. As a result of these efforts, Mark was invited to author American Hospital Association (AHA) Best Practices in Energy Procurement (2017), Business Planning for Energy Resiliency (2018) and Financing Energy Sustainability (2021).
Internationally, Mark spent many years promoting public health efforts through the introduction of clean-energy alternatives in the UK, Eastern Europe and Latin America.
