About Winemaster Gary S

Gary S. Winemaster is best known as the founder of Power Solutions International (PSI), a U.S.-based company focused on power systems and alternative-fuel engine technologies. Company disclosures indicate that he co-founded PSI in 1985 with members of his family and played a central role in building the business over more than three decades. Before stepping back from day-to-day leadership, he served as Chief Executive Officer and President, and also chaired the board for a significant period, helping guide the company through expansion, product development, and structural growth. His leadership history at PSI dates back to the company’s early operating roots. PSI states that Winemaster served as Chief Executive Officer and President of Power Great Lakes beginning in 1992, an operating entity that later became a wholly owned subsidiary of PSI after the group’s corporate evolution. He later led the company at the consolidated level and remained one of its defining executives during its growth phase. PSI announced that he ceased serving as Chief Executive Officer and President in April 2017, at which point he transitioned into the role of Chief Strategy Officer. In that capacity, his focus was on developing and facilitating PSI’s relationship with Weichai, the company’s strategic investor and collaboration partner. In May 2019, PSI announced his retirement after 34 years with the company. From a governance and strategy perspective, Winemaster helped steer PSI through key stages of industrial scaling, product diversification, and market expansion. PSI has said that, under his tenure, the company shipped engines and power systems to leading global equipment manufacturers and industrial customers. His career is closely associated with PSI’s long-term emphasis on alternative fuels, emissions-certified solutions, and applications across industrial and on-road markets. For SEO and executive biography purposes, his most notable role is best described as former Chief Executive Officer and Founder of Power Solutions International.
