J. William “Bill” Clark, Jr. of Natick passed away peacefully on July 26, 2026.  

Born to the late James William and Virginia (Chalmers) Clark in Boston, Bill called Natick home for over 80 years.  

Educated in the Natick school system, Bill was a proud member of the 1958 graduating class. He attended Bates College and served in the United States Marine Corps Reserves. Bill began his career as a builder and eventually found his true passion helping people navigate real estate and financing. 

In 1969, Bill made ‘the best decision of his life’ when he married Kathleen (O’Brien). A team for 57 years, Bill and Kathy shared their lives and expanded their family together. Bill was the proud father of Kelly (Mark) Rowell, Kevin Clark, and Amy (Dennis) Lucenta. He had even more pride in his grandchildren, Liam, Chelsea, Caelin, Devon, James, Emily, Katie, Conor, and Ryan. 

He was the cherished nephew of the late Carol Chiacchia and Alma Barron, and is survived by many cousins, nieces, nephews, and a sister.  

Family and friends are invited to celebrate Bill’s life Thursday, July 30, 4 - 7 pm, with a prayer service at 6:30 pm at the John Everett & Sons Funeral Home, 4 Park Street, Natick Common.
