It is with much sadness and great love that the family of John (Jack) Brennan Jr. of Avon, NJ, shares the news of his passing. Jack passed peacefully from this life due to complications of myasthenia gravis, surrounded by his loving family on August 31, 2023.
Jack was born in Glen Ridge, New Jersey on January 28, 1946 as one of six children born to Josephine and John Joseph Brennan Sr. A devout Catholic, Jack attended Immaculate Conception High School in Montclair, NJ. After graduating, Jack attended Iona College where he earned a BS in English and Theology. He also earned master degrees from Columbia University and St. John’s University. Jack then began his nearly 45-year career in education. Jack, a former Irish Christian Brother, taught at Catholic Memorial High School in Boston before he began teaching at Dominican College. It was at Dominican that he met his best friend, future wife and partner in life, Mary (Dean).
After working at Dominican for several years, Jack began to work at his alma mater, Iona College. After faithfully serving the Iona community, Jack began working at Manhattan College as the Dean of Admissions and Financial Aid. During his time at Manhattan, he assisted countless families to achieve their dreams of having their children graduate from college. Jack was always student focused and willing to lend a hand to any of the men and women at the college. During this tenure he was honored as the Parent of the Year, inducted into the Pen and Sword Society and for his professional acumen was elected as President of the National Association of Collegiate Admissions Counselors.
His love of service and dedication to the students led him to his next stop – Christian Brothers Academy in Lincroft, NJ. Jack worked as the Director of Guidance where his tireless efforts and unwavering support of the boys at CBA enabled many of them to succeed not only in college but in life. Jack was a man of faith who supported, started and sponsored many philanthropic and faith-based events during his lifetime. For his dedication and service, Jack was inducted into the Hall of Fame of St. Joseph Regional High School in New Jersey, the Hall of Fame of Christian Brothers Academy and was selected as the LaSallian Educator of the Year, as well as countless other honors.
Jack was well known for taking the time to speak with everyone, to always lend a helping hand and to have a story for every occasion. Jack was known for his willingness to listen to any problem and to provide very specific guidance. Jack was a family man who valued integrity, honor and loyalty above all else. The legacy he shared with all he met was to remember the important things in life: faith, family and friends. He shared with all he met along his 77 year journey many stories about his own life and all the funny and wonderful memories he had. He had a strong devotion to the Blessed Mother and considered his trip to Lourdes and the many churches in Europe as cherished memories.
His most treasured times were spent with his children, especially the adventure of going to a Notre Dame football weekend with his 5 children to celebrate his 70th birthday. Jack loved life at the shore and was happiest sitting looking at the ocean.
Jack’s most enjoyable times were with his grandchildren, they gave him life, laughter, unconditional love and the strength to fight his myasthenia gravis for over 12 years. Jack was truly their special Grandpa!
