PSSO is an all-volunteer community orchestra led by Maestro Alan Shen and the Board of Directors. I was a member of this orchestra for 5 years and have experience with community orchestras in various cities across the country. What sets PSSO apart? 1) PSSO runs very lean and is able to keep ticket prices low. This helps with community outreach and accessibility. 2) The warmth and welcoming atmosphere for members at rehearsals and audience members at concerts. 3) The dedicated repeat concert-goers. Musically speaking, this is the best bang for your buck for music in the greater Seattle area!
