J. Andrés Ballesteros composes music for a wide range of ensembles (from middle school to professional) and media (from short films to apps) and teaches music at the Boston Arts Academy using innovative curricula and techniques.

He has collaborated with numerous musicians from around the world and seeks to engage with many musical traditions.

He teaches music history, music theory, ethnomusicology, and creative writing at the Boston Arts Academy, most of them using original curricula whose current focus includes emphasizing the role of women in music and highlighting international connections. He remains an active member of his community through work and engaged citizenship via the Franklin D. Roosevelt Foundation (working on environmental causes and global citizenship) and the Boy Scouts of America (working on inclusivity), among others.
