In her work with young people, Dr. Larson wrote the libretto and music for The Picnic or Teresa and the Youfoes in 1981 for Spring Hill Elementary School in McLean, Virginia. The play was revised in 1991 for a performance at The Academy of Movement and Music in Oak Park, Illinois, and in 1994 became the basis for The Youfoe Trilogy, written for the children of Play's the Thing!, a series of musical theatre workshops at Catholic University of America, of which she was musical director beginning in 1994. She was also founding president of Theatre & Song, launched in 1999 to produce Sky's the Limit, a workshop series for teens for which she wrote new music. For both of these workshops she received grants from the American Composers Forum's Community Partners Program
