Dianne McAllister of Carteret passed away surrounded by the love of her family on Saturday, June 6, 2026, at Bayshore Hospital in Holmdel.

Dianne lived life to the fullest and did it with style. She was funny, outgoing, and never met a stranger she couldn’t make smile. A true diva in the best sense of the word, she loved looking her best, making an entrance, and bringing laughter wherever she went.

She was always ready for a party, a good story, or a chance to dance and celebrate life. Her vibrant personality, sense of humor, and love for family and friends made her someone people naturally gravitated toward. She touched countless lives and will be remembered for the joy, laughter, and sparkle she brought to every room she entered. She had a beautiful soul, a powerful presence, and an irreplaceable part of our hearts.

Born on February 19, 1946, to the late Frank and Estelle Serio in Newark, she resided in Carteret most of her life before retiring to Florida and returning to New Jersey 5 years ago.

Mrs. McAllister was a waitress at the Premium Diner in Avenel and Perkins in Colonia for over 25 years before retiring in 2003.

In addition to her parents, she was predeceased by her husband, Donald McAllister, who passed away in 2005, and her brothers Louis Serio and Frank Serio.

She is survived by her daughters Anna Marie Cuevas and her husband Robert of Spotswood, NJ, Patricia Ramos and her husband David of Staten Island, NY, Dianne Rinaldi and her husband Michael of Freehold; a brother Edward Serio of Pennsylvania; ten grandchildren and nineteen great-grandchildren.

Funeral will take place on Friday, June 12, 2026 10:00 am at Costello-Koyen Funeral Home, 399 Avenel Street, Avenel. Entombment will follow at Woodbridge Memorial Gardens.

Visiting hours will be on Thursday, June 11, 2026, from 4:00 pm until 8:00 pm at the funeral home.
