Nicholas Fonte

Executive Director

[email protected]

Nicholas considers himself blessed to serve the Lord through John XXIII's mission. "God prepared me for this opportunity throughout my spiritual and professional life." Before joining the Center, he served as the Director of Leadership Development for Cana Family Institute, responsible for the leadership formation of hundreds of leaders throughout the nation. He also led a Minnesota Catholic parochial school's transition from the traditional education model to the Montessori method. At a pivotal moment in the school's history, he spent years building a family-focused, joyful community of children, parents, and staff. 

Two decades ago, he graduated from the University of Notre Dame with a Bachelor's Degree in Great Books, in which he studied the seminal works of Western philosophical, theological, scientific, and literary thought. Following college, he lived and worked in a Catholic orphanage for two years in Honduras, where he encountered Christ in the poorest of the poor. Soon after, he experienced a clear call to serve God through His Catholic schools. Nicholas served as a high school teacher and campus minister before pursuing a master's degree in Theology at the Pontifical John Paul II Institute for Marriage and Family Studies in Washington, DC. He then joined a team of educators led by the Nashville Dominican sisters, which founded Saint John Paul the Great Catholic High School, where he served as a religion teacher and the Dean of Instruction & Student Life. During this time, he earned a master's degree in Educational Leadership from the University of Notre Dame. In June of 2016, he received a phone call inviting him to be a Catholic school principal in Minnesota. However, his thin California blood did not adapt well to the cold, and he was delighted to return to Virginia in 2020. "The Lord blessed me with the opportunity to lead John XXIII, and my wife, four children, and I remain ever-grateful to call John XXIII and Front Royal our home."
