The Excelsior Symphony Orchestra (formerly known as the St. Thomas Orchestra) was co-founded by Bernard Tamosaitis and Peter Arike in 2002. Among its ranks today can be counted a broad spectrum of professionals in the arts, sciences, law, finance, medicine, and business. Members in the orchestra range in age from 15 to 85 and are united by a common commitment to the pursuit of musical excellence. Over the years, we have evolved into a uniquely diverse organization of remarkable depth and it is our privilege to perform great symphonic music for our community.

Our Mission

The power of music is to transport us outside of day-to-day concerns and into an unfettered realm of communal epiphany. It is our hope that the orchestra will serve as a bridge to make great symphonic music more accessible to our community.
