Board of Directors


DJ Castilleja started with the SMART Orchestra in 2021 as a very talented section leader for our french horn section. He has been playing the french horn since 1992 when he began learning in Middle School. A few words from DJ: “What I love about performing in an orchestra is the multi-faceted art form that it is. First is the art of writing a piece of music that someone dedicated heart and soul to compose, sometimes taking months or years. Then each individual performer gets a piece of the big picture and has to be an artist in their own parts with their own instruments. All the individuals then come together to form one big piece of art in the performance all done in real-time by the leading of a conductor“.

VP Community Relations

Kwin Lara has performed with the SMART Orchestra for 4 seasons and has served as our VP of Community Relations for 2 years.
