Margaret Sullivan — Board Member
Margaret is someone for whom, as a result of the sound, the beauty, and the emotion, music creates an elemental “feel” that is appreciated on a number of levels. Her background in German studies, history, and education inspired her while in Europe to explore music first as a listener, and then as a participant in choirs sacred and secular. She shares her interest in all aspects of instruments and singing with her sons Daniel and William, who are also very musical. She has worked at Milton Academy directing Understanding Differences, a program that teaches fourth graders about individuals with learning and living challenges. In addition to her participation on the Board of Calliope, she sits on the Board of the Maria Droste Center, which supports recovering individuals who capitalize on their talents such as music, ultimately playing a significant role in redirecting their lives. She was a vibrant part of Calliope’s pilot season.
