Our History

Located on Martine Avenue in Scotch Plains, Union Catholic opened its doors on September 9, 1962, as two schools within one building: Union Catholic Boys High School and Union Catholic Girls High School.

The Marist Brothers oversaw the education of the boys' school, while the Dominican Sisters led the girls' school. Together they established a strong academic and spiritual foundation rooted in faith, service, and community.

In 1980, Sister Percylee Hart, RSM, began her extraordinary 45-year tenure as principal. During this time, the two schools were unified into one coeducational community.

Today, under the leadership of Principal Dr. James Reagan, Jr. '96, Union Catholic carries forward its tradition of faith, academic excellence, and community while preparing the next generation of leaders.

Where Tradition Meets Tomorrow

Slide 1

Where Tradition Meets Tomorrow

The traditions of our school community build the foundation for every student's future.

At Union Catholic, tradition is not simply remembered. It is lived.

Slide 2

Where Tradition Meets Tomorrow

It is reflected in the pride of students who call this place home, the accomplishments of our alumni, and the enduring faith that unites our community. Generations of UC graduates have carried their faith, character, and work ethic into every field becoming leaders, innovators, advocates, and role models.

A group of young men, likely freshmen, are shown in a formal portrait setting, with the text %22YEAR 1%22 and %221234%22 prominently displayed in the background.

The story of Union Catholic is three histories: the history of a building, of a family, of a person.
