John, the eldest of five children, has been a Woodbridge resident since 1960 when his father, an Irish immigrant and steel plant foreman, and mother, the daughter of Irish immigrants, bought their first and only home in Menlo Park Terrace. After graduation from St. Cecelia's grammar school in Iselin and St. Thomas Aquinas High School, class of 1976, John went on to earn a Bachelors Degree in Accounting from Rutgers University and a Masters Degree in Finance from St. John's University. John met his wife Tammy, now a Manger of Customer Financial Services for Bristol -Myers Squibb, while they were both students at Rutgers University. They wed in 1983, and moved into a home in Iselin. They now live in Colonia with their daughter, Erin, a sophomore at Duquesne University.

A Certified Public Accountant, he worked for eight years for a large international CPA firm, with both Fortune 500 companies and small local governments on its client list. In 1988 John started his own CPA business, relocating it to downtown Woodbridge three years later, where he was able to help hundreds of Woodbridge residents with tax questions and financial concerns. John's competence and skill caught the attention of then Mayor Jim McGreevey. John, being fiscally conservative, was able to restore integrity and order to the town's finances.

In 2002, after Mayor Jim McGreevey was elected Governor of New Jersey, he asked John to come with him to Trenton, and to serve the citizens of New Jersey as their State Treasurer. In that position, John supervised 12 Divisions and 3,500 employees in various areas.

While in office, he represented Governors McGreevey and Codey in fiscal related matters with the Legislature, media, and constituent advocacy groups. His efforts to attract and retain business helped keep New Jersey moving forward and at the top of national rankings for jobs and growth. In 2004, when state Senate President Richard Codey took over as Acting Governor, he asked McCormac to stay on as Treasurer. John was happy to stay and finish his term.

Now, at 51 years old, with a 14-year history of community service behind him, John has come back to the town he was raised in, with the hopes of leading it with the same energy and vision that helped move both Woodbridge and the State of New Jersey forward.
