From Millburn High School in Millburn, New Jersey, Mulcahy headed to Villanova University, where he graduated with a Bachelor of Arts in History. Following graduation, he served in the Navy, and at just 23 years old, Mulcahy ran successfully for a Mendham, New Jersey Councilman seat. Committed to serving his community, he later served as Mayor of Mendham, New Jersey’s first Corrections Commissioner, and Chief of Staff to former NJ Governor Brendan Byrne. In 1979 he was appointed President and CEO of the New Jersey Sports and Exposition Authority, a position he held for 19 years before beginning his tenure as the Athletic Director at Rutgers University in 1998. Mulcahy used his personal and political contacts to raise the Athletic Department’s endowment and obtain state funding for a massive renovation of Rutgers’ athletic facilities and won increased television coverage for the school’s football team. 

Mulcahy is known for his love and pride for New Jersey, and was instrumental in saving the Pinelands, New Jersey hosting the World Cup and the NCAA Men’s Basketball Final Four, Pope John Paul II’s visit to celebrate mass at Giants Stadium, and bringing the NY Jets and the NHL Devils to New Jersey.
