Faculty & Staff Directory

Adam Dickerson, JCL, M.A.
Headmaster

Mr. Dickerson and his wife Sarah live in Willow Grove, along with their seven children. Adam attended high school seminary and diocesan seminary, where he received his bachelor's in philosophy. He also has a licentiate in Canon Law from the Catholic University of America and an M.A. in Theology from St. Charles Borromeo Seminary. Adam taught moral theology for almost ten years at Archbishop Ryan High School. Next he worked for nearly another decade as a canon lawyer at the Archdiocesan Marriage Tribunal, working with couples on marriage annulments. Working at the tribunal inspired Adam to want to proactively help couples form solid sacramental marriages so that they would never need the tribunal. Before long, working in marriage prep programs convinced Adam that he had a calling to help provide Catholic moral formation to young people long before the threshold of marriage. Today Adam is thrilled to return to high school teaching to better equip young people to run hard after truth, beauty and goodness despite the challenges of our post-Christian era.
