Rachel Levin, Site Director, St. Patrick’s Episcopal Day School

Some new adventures included flying on a trapeze, performing in a singing group, and camping and sleeping under the stars. Each experience was memorable and meaningful because it took her out of her comfort zone and helped her learn to take risks.
