Colleen Nevin Mahoney
January 10, 1979 – December 20, 2018

Relatives and friends are invited to attend the funeral Mass on Friday at 10am at Immaculate Conception Church, 30 North Fullerton Avenue, Montclair, NJ. Interment will follow at Immaculate Conception Cemetery. Visitation is on Thursday from 4 to 9 at O’Boyle Funeral Home, 309 Broad Street, Bloomfield, NJ.

To know Colleen Mahoney was to love her. Her infectious laughter, fun-loving and determined spirit made it a joy to be in her presence.

Born and raised in Glen Ridge, NJ, Colleen graduated from Glen Ridge High School in 1997 and went on to graduate from The Catholic University of America in 2001 with a degree in Communications. Colleen then embarked on a successful 17-year career in advertising at CBS, Carat, and most recently at OmniCom Media Group in New York, NY.

Colleen completed the New York City Marathon in 2009, 2010, and 2014. Each time she ran, Colleen raised funds to benefit Memorial Sloane Kettering Cancer Center as a part of Fred’s Team in memory of her mother, Mary Clare Mahoney, who passed away after a long battle with a rare blood cancer in 2004.

Perhaps Colleen’s greatest role was that of “Aunt Coll Coll” to her 11 nieces and nephews. From her annual excursions to New York City for the Thanksgiving Day Parade, her extraordinary Easter Egg Hunts, to simply a sleepover or a day at the beach, every day spent with Coll Coll was special. Her natural ability to make children feel loved and unique was beyond compare and is something these children will carry with them for the rest of their lives.

Colleen was diagnosed with metastatic breast cancer in 2015, one year after her final NYC Marathon. As she embarked on this last ‘marathon’ versus cancer, she was surrounded by the love of her family, her childhood and school friends, and her work friends who all became more like family over the years. Through every treatment, procedure, complication, and hospital admission, her loved ones were there to provide support during each setback and to share in the moments of joy for every victory no matter how small.

Colleen is survived by her father, Hugh Mahoney of Glen Ridge, NJ; her sister, Tara, and her husband, Jeffrey Easter, and their four children: Brendan Thomas (16), Kevin John (15), Daniel Stuart (13), and Mary Clare (11), of Glen Ridge, NJ; her brother, Timothy Mahoney, his wife, Margaret, and their four children: Martin Joseph (15), Nevin Mary (14), Patrick Hugh (12), and Catherine Doyle (10), of Mendham, NJ; and her brother, Daniel Mahoney, his wife Mary, and their four children: Jack Maginnis (11), Ryan Rocque (9), and Connor Patrick (8) of Cranbury, NJ.

For those who wish in lieu of flowers, donations may be made in Colleen’s memory to Somerset Hills Learning Institute where Colleen visited often to assist her niece Catherine, a student there.
