Joseph A. Grzyb, CEO at Phase Change Energy Solutions since 2015, has left PCES to join Dan Cook as a partner at Conservation Solutions Corp.
Boston-based CSC provides corporate customers with energy and water conservation solutions, including PCM products from Phase Change Energy Solutions of Asheboro, N.C.
"CSC has been a leading distributor of products from Phase Change Energy Solutions for several years," Grzyb, right, wrote in an e-mail sent late Friday to companies involved in the recent formation of the PCM Industry Association of North America. "My focus at the firm is to expand the business and provide engineered PCM solutions to companies across North America."
Gryzb was elected president of the PCM association in October. The association's mission is to promote the development and use of phase change material in North America.
"I would be pleased to continue in the role of president until our next association meeting later this year (date TBD)," he wrote in Friday's email. "I propose that during our next meeting, we have a new vote for association president."
Jan Kosny, the association's executive director, expressed confidence that association work will continue "without any disturbance," since Grzyb plans to serve as president until the next annual meeting.
