David P. Haney, age 78, of Wilmington, Delaware, passed away peacefully on Saturday, November 1, 2025, at Kutz Rehabilitation and Nursing Home, surrounded by his loving family.

Born and raised in Wilmington, David was the son of the late Pauline (Mahoney) and George Haney. He was a proud graduate of St. Edmond's Academy and Salesianum School. Following his education, David enjoyed a long and fulfilling career with the DuPont Company, from which he retired, before continuing to work for VWR and Mealey Funeral Home.

A man deeply rooted in faith and community, David was a longtime parishioner of St. Anthony of Padua Church. He dedicated countless hours volunteering at St. Anthony of Padua Grade School, the Italian Festival, and Padua Academy.

Family was the center of David's life. He found great joy in attending his children's and grandchildren's sporting events and celebrating their achievements. He will be remembered for his kindness, generosity, and steadfast devotion to those he loved.

David is survived by his beloved wife, Helen (Kaminski) Haney, and her children; his daughters, Jennifer (Jeff) Thomas and Allison (Dennis) Leizear; his grandchildren, Alexandra (Michael) Thomas and Nathan (Erica) Thomas; his brother, Chuck (Janice) Haney; his nieces, Megan (Steve) Yash and Shea (Devin) Canup; his nephew, Matthew (Mary) Haney; and his great-niece and great-nephews.
