Mr. Walls is an enthusiastic and patient teacher. As a choir member at Saint Elizabeth Ann Seton for the past fifteen years, I have been able to sing liturgical music, and participate with other choirs in singing more complex pieces of music, such as requiems and compositions for rites of the church and special occasions. Our choir has sung in various languages, and joined other choirs in ecumenical choir fests. Mr. Walls has studied music composition, conducting, and history, and is an accomplished musician on several instruments, including the piano, organ, and guitar. He has several years teaching experience in the U.S. and abroad. I would say Mr. Walls' expertise and talent are second to none.
