David Semplenski

Born on December 1, 1940, in Seymour, Connecticut, David was the beloved son of the late Frank and Clara (Wisniewski) Semplenski.

David was a devoted sports fan who faithfully cheered for the New York Giants, New York Yankees, New York Rangers, and he was an avid fan of the UConn Women's basketball team. His passion for athletics extended beyond being a spectator. He enjoyed playing softball for several local championship teams, including Wingate, DiGirolamo Construction, Seymours, and Newark PD softball teams. For more than 25 years he was a local umpire with the Amateur Softball Association (Livingston division) for men’s & women’s town softball leagues as well as Livingston girls softball teams.

David proudly served the City of Newark as a Police Officer for 20 years. He approached his career with dedication, integrity, and a strong sense of duty, earning the respect of those who served alongside him and the community he protected. After retiring from the Newark Police Department, Dave worked as an investigator with the Sumas Family corporation of ShopRite stores in New Jersey.

Above all else, David was a devoted husband, grandfather, and great-grandfather. His greatest joy came from spending time with his family.

David was preceded in death by his parents, Frank and Clara Semplenski; his sister, Claire Nystrom-Arnold; his brother, Frank Semplenski; and his sister-in-law, Helen Semplenski.

He is survived by his beloved wife of 57 years, Donna Semplenski; his children, Pam Clare, Marci Tanelli (Ron), Frank Semplenski (Marissa), David Semplenski (Mary), and Sandra Cestaro and grandchildren, Jack, Pierce, Riley, Ava, Sammie, Emma, Mia, Matthew, David Jr., Mary Kate, Nicholas, Justin, Kristin; and his great-grandchildren, Carter, Kayla, Jordan, Jace, and Gianna.
