Judge Mary Costello was born in Kearny and was raised in Harrison. She attended Lincoln School and Harrison High School. After earning a Bachelor’s Degree from Seton Hall University in 1981, she went on to earn her Juris Doctor from the University of Richmond in 1985. After graduating from Law School, Costello worked for various law firms throughout northern New Jersey. In early 2007, New Jersey Gov.

Judge Costello was formerly a Member of the Board of Governors for the Archdiocese of Newark Youth and Young Adult Ministries (CYO) for ten years.  She was a founding member of the Golf Outing Committee for Josephine's Place in Elizabeth, NJ and also served on the Board of Kenmare High School, part of the York Street Project in Jersey City.  All charitable pursuits had to cease upon her appointment to the Bench since judges are prohibited from engaging in any political or charitable fundraising.  

Judge Costello has been married to Jim Hague for 23 years. Hague is a freelance sportswriter for various publications throughout northern NJ including The Observer.

Upon hearing that she had been elected Grand Marshal, Judge Costello said, “I was thrilled to be so honored. We are given too few opportunities to celebrate our heritage and diversity in a public forum, so to be able to do so at the parade and all the associated events is a special treat for me as an Irish-American woman from Hudson County.  My parents, sadly, are both deceased.  My father's family came from County Galway and my mother's family came from County Tipperary.  I dedicate my service as Grand Marshal to their memory."
