DONAL (DON) DUFF
Beloved husband, father, brother, and friend Donal “Don” Duff passed away on May 31, 2025, at the age of 58 after a courageous battle with ALS.

Don is survived by his loving wife of 30 years, Barbara (née Kouvel); his children Christen, Brendan, and Tyler; and his siblings Patrick and his wife Mary, Mary Koury and her husband Joe, Maureen Longway and her husband Chad, and Eileen Blalock and her husband Jamie, along with cherished nieces and nephews. He was predeceased by his parents, Donal and Jane Duff.

Don was born on November 21, 1966 and was raised in Waldwick, NJ. He graduated from Don Bosco Prep HS, earned his bachelor’s degree at the University of Delaware, and completed his masters at St. John’s University. He raised his family in Glen Rock before moving to Hoboken. 

For 30 years he had a successful career at Aon. Colleagues remember his knack for turning clients into friends through his overwhelming generosity and quick witted humor. Beyond this, he was known for mentoring the next generation of insurance professionals demonstrating his strong desire to help others.

Away from the office, Don lived his life to the fullest: cheering on Notre Dame football and New York sports teams, attending countless concerts, and travelling the country to fulfill those passions. Throughout his life Don made endless life long friends, bringing people together to create numerous memorable nights. He went above and beyond for those around him and was the ultimate entertainer.  

Above all else the most important things in Don’s life were his faith and his family. His devout Catholic faith was the foundation for the way he lived his life, and as a dedicated family man, he always put his family first in everything he did.

Visitation will be held on Sunday, June 8, from 1:00 – 5:00 p.m. at Vander Plaat Funeral Home, 257 Godwin Ave., Wyckoff, NJ. A Mass of Christian Burial will be celebrated on Monday, June 9, at 11:00 a.m. at St. Luke’s Roman Catholic Church, 340 Franklin Tpke., Ho-Ho-Kus, NJ. Interment will follow at St. Luke’s Cemetery.
