David L. Marconi

David L. Marconi, 76, of 549 Brusselles Street, St. Marys passed away peacefully with his family by his side Wednesday, October 15, 2025 at Highland View.

He was born, February 20, 1949, in St. Marys, son of the late Victor E. and Mary Margaret Henkel Marconi. David was a lifelong resident of the area, a graduate of St. Marys Area High School, Class of 1967, and employed with PennDot for thirty-five years. 

On November 21, 1970, in Sacred Heart Church, David married Cynthia Walsh, who survives. They were blessed to share fifty-four years of marriage.

In addition to his wife, Dave is survived by his daughter, Michelle Sullenberger (Keith) of Centreville, VA and his son David “DJ” Marconi (Mandy) of St. Marys; two grandchildren, Breanna (Anthony Whitaker) and Ben; and a sister, JoAnne Marconi of Buffalo, NY; and many aunts, uncles, nieces, and nephews.

In addition to his parents, he was preceded in death by his sisters: Catherine Cuneo and in infancy, Mary Ann and Mary Grace Marconi.

Dave was passionate about football at an early age. He was so dedicated that he had the opportunity to play at the collegiate level at Hiram Scott College in Nebraska. He continued this passion and shared it with the youth in the St. Marys community by coaching the Stallions and the Dutch football programs. He was a die-hard Raiders fan and shared his love of all sports with his son at the store that they co-owned, D&D Sports Cards. Dave always found a way to contribute to his community. He was a Little League coach, Boy Scout Leader, a member of the Tri-County fire police, and Captain of the fire police with the Crystal Fire Department. 

A Mass of Christian Burial will be held in the Sacred Heart Church on Monday, October 20, 2025 at 10:00AM with Rev. Thomas Curry, O.S.B., celebrating. Burial will follow in the St. Mary’s Catholic Cemetery.

David's family will greet family and friends at the Maurus Street entrance of Sacred Heart Church from 9:30AM until the time of Mass.
