Alejandro Lleras, Board Member

Alejandro Lleras hails from Venezuela as a direct musical descendent of Sistema founder, Dr. Jose Antonio Abreu. He works as a Human Resources and Faculty Affairs Manager for the Department of Surgery in the School of Medicine at the University of Colorado Anschutz Medical Campus.

Sistema was part of his family’s daily lifeblood growing up. Alejandro played clarinet from the age of seven and within a few years became a member of Sistema’s top youth orchestra in Venezuela alongside Gustavo Dudamel, Sistema’s most famous graduate and longtime Los Angeles Philharmonic Music Director. The orchestra was conducted by Maestro Abreu, who taught Alejandro first-hand the power Sistema has to build life-skills, “affluence of spirit” as Abreu put it, and the vitality of an entire community. He was recruited into the esteemed Interlochen Arts Academy High School in Michigan and later received his Music Performance Degree from the University of Colorado School of Music in Boulder. Alejandro emits Abreu’s deep passion. His inspiration is infectious when sharing his story with our young musicians or others.

Carrying on Abreu’s legacy, Alejandro is critical in shaping the direction of El Sistema Colorado, be it through insights about core principles or program philosophy and design. Alejandro is also excited to be returning to his musical roots and looking forward to teaching clarinet on a volunteer basis.
