Jaime Castillo is Colombian, a music professional with a "day job" in another field. In 2015, he offered a performance and workshop in Front Royal, VA. His Facebook page says he is "Project Manager with a major US company; 26years coaching soccer; Professional Harpist."

An excellent performer and teacher; I met him when he came to Front Royal, VA, in September, 2015. 

Here are a few video clips.
