Blue and white caps flew into the air by Federal Hall June 1, marking the graduation of the first senior class at Léman Manhattan Preparatory School in the Financial District. The 20 students from the private school’s Class of 2013 made the symbolic walk across the stage at a ceremony in its 41 Broad Street Ballroom. The student speaker, Sam Sherman, will be attending Duke in the fall. The Class president, Mikayla Barnett, will be attending the University of Pennsylvania’s Wharton School for business.
