In addition to his service to PSI, Winemaster has served on the board of directors of Avon Old Farms School, an independent boarding school in Connecticut, since 2014. He also served on the Caterpillar Industrial Strategy Council from 2001 to 2015, a council that developed market strategy for Perkins Distributors and CAT Dealers in North America.

“As I planned my retirement this past year, I had time to reflect on my 36 years with PSI, and I feel very fortunate to have had the opportunity to work together with my father, who served as a professional mentor and provided such a wonderful opportunity for all of us,” said Winemaster. He continued, “I will also truly miss working with the people, who over the years, worked tirelessly to help the company accomplish so many positive things. I look forward to seeing them continue that legacy of quality and service well into the future.”
