GSG Announces Passing of Lenny Diaspro

With deep sadness, GSG announced the passing of its valued sign territory manager, Leonard “Lenny” G. Diaspro, on Friday, Oct. 18, 2024. With over 40 years in the sign industry, Diaspro was a passionate sales leader and a respected member of the sign industry.

Diaspro was a co-owner of Cincinnati Sign Supply and in 2016 sold the company to GSG where he continued his sales career. He was known for his fun-loving enthusiasm and his ability to build strong relationships with customers and suppliers, earning widespread admiration across the sign industry.

For 25 years, Diaspro held numerous leadership roles at Midwest Sign Association and chaired 15 golf tournaments for the association. He led the Business Advertising Council of the Cincinnati Sign Association. In 2024, the American Sign Museum honored Diaspro for his volunteerism and support, by naming the bar and refreshment area Lenny’s.

Mark Granberry, GSG CEO noted, “Lenny was a unique individual. He always had a smile on his face and was willing to help anyone who asked. You couldn’t help but love the guy; he brought a fun-loving spirit to the team and was the kind of person every sales organization wishes they had on their team.”

“Our family lost a life-long friend, a mentor, No. 1 Bengals fan, and soccer and hockey player. The sign industry lost a legend. Rest in Peace Lenny Diaspro, you’ll be deeply missed,” said Joe Pisel, Sign Source USA.

Diaspro is survived by his loving wife, Kelly; sister, Maria Rzecznik; brother, Mark Diaspro; beloved dog, Dominic; as well as nieces, nephews, extended family, and many friends. A visitation was held on Thursday, Oct. 24. at the Belton-Stroup Funeral Home in Fairborn, Ohio.

Memorial donations can be made to the American Sign Museum or the American Heart Association.
