Meet the Principal


Mary Jane Cooney, Principal

Mary Jane Cooney, Principal

Mrs. Cooney grew up in the Berkshires and attended St. Joseph Regional High School and Massachusetts College of Liberal Arts. She received her Bachelor of Science in elementary education and worked as a substitute teacher for three supervisory unions in Massachusetts and southern Vermont. Mrs. Cooney and husband, Richard, moved to southern New Hampshire in 1979 shortly after getting married. They raised two daughters and sent them to St. Thomas Aquinas School in Derry, NH. It was there that Mrs. Cooney became an active participant in the school as a volunteer, president of the parent guild, and as a substitute teacher. She continued to be a supporter of the school when her grandson also began attending in his kindergarten year.

When their eldest daughter and family moved to the Lakes Region in the fall of 2012, Cooney and her husband were not far behind. Her grandson then began attending Holy Trinity and Cooney became active again as a grandparent, volunteer and substitute teacher. She became Principal in July 2014. Her husband passed away in March of 2015, after a long battle with cancer.

Cooney has a strong track record as a school administrator for fourteen years, as well as a kindergarten teacher for ten years. “In all of my work experiences, the Christian life has always been a guiding light for me. In our world today, greater sacrifices are required in order to be a true and practicing Catholic, when more of what we stand for and what we believe in is going to be challenged. It takes strong faith to encounter all this and not accept the wisdom of the world.”

Educating young people to serve and give of themselves freely is one of the hallmarks of Catholic schools and will continue to be an integral part of a Holy Trinity student’s learning and experience. Our Catholic education will prepare students to be good stewards of God’s gifts and active people of faith who serve others and make a difference in the world. The atmosphere is supported by teachers who serve as strong Christian role models and assist students not only with their academic and personal growth, but their spiritual journey, as well.

“I am blessed and honored to be a part of this wonderful community of faith, and together, with God’s help, we will continue to build on the many blessings that God has given us.”
