The North American Sustainable Refrigeration Council (NASRC) has announced changes to its leadership, appointing co-founder Keilly Witman as President and Chief Executive Officer, Todd Ernest as Chairman of the Board, and Ben Rosenzweig as a new Board director. The appointments support NASRC’s work to facilitate the transition to natural refrigerants.
Witman, one of NASRC’s original founders, previously managed the U.S. Environmental Protection Agency’s GreenChill program and has experience in refrigerant management and regulatory compliance. As President and CEO, she will focus on helping food retailers overcome barriers to natural refrigerant adoption through practical solutions, workforce development, and access to funding.
Ernest has served on NASRC’s Board since 2019 and brings experience as a refrigeration contractor through his work with Climate Pros. As Chairman, he will help align the organization’s priorities with the needs of businesses and technicians installing and servicing natural refrigerant systems. He identified technician training as a key priority for implementing these technologies.
Rosenzweig, President of Professional Solutions at CoolSys, joins the Board after years of involvement with NASRC, including participation in its CO2 Technical Committee. His background in refrigeration engineering and energy management will contribute to the organization’s technical priorities and efforts to address implementation challenges.
The leadership changes come as NASRC continues its work on technical guidance, workforce development, and collaboration among retailers, manufacturers, and contractors. “As a contractor, I see it every day: we have to train the next generation of technicians to install and service these systems, or none of the progress happens in the store,” said Todd Ernest, Chairman of the NASRC Board.
