After almost 25 years of overwhelming success with the Marimba Ensemble at Holy Cross Parish in Chicago the Claretians expanded their marimba program to give more young people the opportunity to develop leadership and teamwork skills, mentoring relationships, and self-confidence and esteem through music education while keeping busy and off the street. In 2013, Claretians and local community leaders started a Marimba Ensemble at San Gabriel Mission in San Gabriel, California.
