The celebrant for the wedding ceremony will be Msgr. Brown from St. Vincent de Paul parish in Stirling, NJ. St. Vincent's is the DiDia family parish. Erin's mom is currently the principal of St. Vincent de Paul school. Erin's sisters have also attended the grammar school.

The ceremony will be held in the chapel at Mount Saint Mary Academy in Watchung, NJ. This is Erin's high school. It's the dream of most "Mounties" to hold their wedding in the chapel. MSMA has a tradition to dress in white gowns for several holy days throughout the year. In participating in the holy days, Mount students envision their wedding ceremony in the chapel. Also, Erin's youngest sister, Mary, is currently a freshwoman at Mount St. Mary's.
