Rochester Businessman and Philanthropist John “Dutch” Summers Dies at 84

John “Dutch” Summers, a prominent figure in Rochester’s business and philanthropic communities, passed away at the age of 84 on Friday.

A Legacy of Business and Charitable Contributions

The son of Jasco Tools founder John A. Summers, Dutch took over the company in his mid-20s and grew it into a global equity firm with business ventures across 17 states and in five countries. Additionally, he held ownership interests in several other businesses, such as The Strathallan Hotel, 3 City Center, and Pittsford Place.

While his business acumen made an enormous economic impact on the community, it was Dutch’s generosity that defined him. He co-founded the Rochester Rump Group, which later merged with the Greater Rochester Chamber of Commerce. Dutch also served as a trustee of RIT and founded the Summers Foundation with his late wife, Jayne, to support educational, health, and human service organizations. Thousands of individuals and families benefited from his financial assistance, given with no expectation of recognition or credit.

A Friend Remembers

Ken Marvald, a longtime friend of Dutch and General Counsel for Graywood Companies, said, “Despite his immense contributions, Dutch never sought recognition for his charitable endeavors.”

A Life of Service and Support

After Jayne’s passing, Dutch married Sandy Parker, former president of the Rochester Business Alliance. The couple continued to actively support numerous educational organizations. Parker passed away in 2023.
