Father Sullivan was the first resident priest the island ever had. According to local history, the rectory as we know it now used to be a convent when he came to the island in1985. The sisters who lived there moved to Englewood to be closer to the Placida Road church, St. Francis. He was also responsible for purchasing the house and property next door to the church, which he renovated into a daycare center, now called the Boca Grande Preschool. The old rectory was sold to a resident, Mark Shevitski, and Father Sullivan moved across the street into the newly purchased house.
