The Christies, both then recent graduates of the University of Delaware, were married in 1986. As newlyweds, they shared a studio apartment in Summit, New Jersey. She and her husband have 4 children: Andrew, Sarah, Patrick and Bridget. The family resides in Mendham Township. Governor Christie has cited his wife's success as a bond trader as enabling him to have a relatively low-paid political career. When a colleague teased him about this, the Governor responded, "Listen, I just have three words for you: joint checking account. That money all lands in the same place, baby. It's fine by me". Mary Pat insisted that the family not move to the New Jersey Governor's Mansion in Princeton, New Jersey, so that the children would not have to change schools.
Career
Mary Pat Christie pursued a career in investment banking, eventually working at a Wall Streetinvestment firm located two blocks from the site of the September 11 attacks. On that date, she lost cell phone reception and was unable to contact her family. Governor Christie has spoken about how long those hours were that day. He was dealing with a disaster that struck an enormous number of New Jersey and New York families, all while having no contact with Mary Pat. He remembers thinking, "What am I going to do without my best friend?", "What kind of single dad am I going to be?" Four hours passed before she was able to cross the Hudson River to New Jersey on a ferry, and someone was able to contact her husband. When Chris came to the ferry landing, he found his wife soaking wet and wrapped in a blanket, having been drenched with water sprayed from a fire hose along with other survivors, to prevent contaminated debris from reaching New Jersey. She became a managing director at the Wall Street investment firm Angelo, Gordon & Co.. Mary Pat has been the family's primary breadwinner, earning $500,000 of the couple's total income of $700,000 in 2014. She left her position with Angelo, Gordon & Co. in April 2015, stating that she wanted to spend more time with her family.
Mary Pat accompanied the Governor as he campaigned in 2015. When he had to return to New Jersey in January 2016 because as the Blizzard of 2016 bore down on his state, Mary Pat stayed in New Hampshire and substituted for the Governor at scheduled campaign stops.
