Maestro Andrew Sewell begins his 8th season with the San Luis Obispo Symphony and his 25th season as Music Director for the Wisconsin Chamber Orchestra. A conductor in demand, he has successfully built the Wisconsin Chamber Orchestra into a regional and nationally known ensemble, and in San Luis Obispo, draws quality musicians to the area for exhilarating performances at the CalPoly Performing Arts Center.

Maestro Sewell has served previously as Music Director of the Wichita Symphony (2000-2010), Mansfield (OH) Symphony (1997-2002) and Resident Conductor of the Toledo Symphony (1995-2000), and Assistant Conductor of the Memphis Symphony (1994-1995).   As a guest conductor, he has led the Toronto, Detroit, Milwaukee, Florida, Columbus, Toledo, Syracuse, Illinois, Monterey, Gulf Coast and Eugene Symphony Orchestras as well as the New Zealand Symphony Orchestra, Auckland Phiharmonia, Christchurch Symphony, Dunedin Symphony, National Symphony of Mexico, Kyushu Symphony (Japan), City Chamber Orchestra of Hong Kong, OK Mozart Festival, Peninsula Music Festival (WI) and Masterworks Festival, Spartanburg, (SC). 

A native of New Zealand, Maestro Sewell received his music training on the violin, piano and cornet, and began conducting at age 16. Six years later, he made his professional opera debut with the Mercury Opera and the Auckland Philharmonia Orchestra. Winning the Australian Guarantee Corporation’s Young Achiever’s Award allowed him to further his studies abroad. Sewell holds a Master of Music degree with Honors in Conducting from the University of Michigan.

Sewell was the first recipient of the NZ Aotea Performing Arts “Star” Award. In 2017, he was awarded the Service to Music Award from the Association of Wisconsin Symphony Orchestras and in 2013, the Rabin Arts Youth Award for Individual Achievement, by the Wisconsin Youth Symphony Orchestra, for his services to youth and education. 

While on the Central Coast, he enjoys cycling, hiking, ocean swims, and local culinary delights.
