The Monmouth University football community is mourning the sudden and unexpected death of defensive coordinator Louis DiRienzo Jr. He was just 34 years old.
The university announced the heartbreaking news in a statement, saying the respected coach, husband and father had made a powerful impact during his short time with the program.
No cause of death has been released.
“On behalf of Monmouth Athletics, we are heartbroken by the unexpected passing of Coach DiRienzo,” athletic director Jennifer Sansevero said.
“Lou was an outstanding coach, mentor and colleague whose passion for developing young men and love for the game made an immediate impact on our football program.”
Sansevero said DiRienzo was remembered not only for his coaching ability, but also for the way he treated the people around him.
“More importantly, he was a kind, genuine person who built meaningful relationships with everyone around him,” she continued.
“Our hearts are with Lou’s family, friends, our football student-athletes and coaching staff, and all those whose lives he touched.”
DiRienzo, a native of Yonkers, New York, joined Monmouth in 2025 as the Hawks’ linebackers coach and defensive run-game coordinator.
Before his arrival, Monmouth had finished with a 6-6 record. The team then improved to 9-3 as its defense became one of the most improved units in the Coastal Athletic Association.
His work helped earn him a promotion to defensive coordinator in January.
Monmouth head coach Jeff Gallo described DiRienzo as “a great person, father and coach.”
“He poured into our players and program, making a tremendous impact during his time here,” Gallo said.
Before joining Monmouth, DiRienzo spent five seasons at Springfield College, serving as defensive coordinator and linebackers coach.
Springfield won four consecutive NEWMAC conference championships during his tenure. In 2023, DiRienzo was named the Gridiron Club of New England Division II/III Co-Assistant Coach of the Year.
His football career began long before he reached the coaching ranks.
DiRienzo played linebacker at Southern Connecticut State University, where he also served as a team captain. He later earned a master’s degree in physical education from Springfield College.
He came from a football family. His father, Louis DiRienzo Sr., was also his high school coach.
DiRienzo is survived by his wife, Allie, whom he married in 2022, and their twin daughters, Audrina and Giavanna.
He is also survived by his parents, Carol and Louis Sr., and his brother, Andrew DiRienzo.
Monmouth’s statement also paid tribute to DiRienzo’s beloved bulldog, Geno, “who meant so much to him.”
Gallo said the football program will stand behind the coach’s grieving family and players.
“We will support Lou’s family and our players through this difficult time and honor him through our daily work,” he said.
“Lou’s presence will remain with our team; energy never dies.”
Longtime Hudson Valley high school sports reporter Kevin Devaney Jr. said he was “shattered” by the news and remembered DiRienzo as an “all-time favorite kid to cover.”
Funeral services are scheduled for Thursday in Westchester County, New York.
