About the Southland Symphony Orchestra

The Southland Symphony presented its first concert in Ontario on Sunday, December 11, 2011. The orchestra’s founder and director, Dr. Sylvia Lee Mann, who had recently relocated to the area, saw a need and an opportunity to bring symphonic music to the larger Ontario Community, a community which was already embracing arts and culture. Since that first concert, we have presented more than 25 free, full-orchestra concerts for this community. We have presented internationally renowned musicians from all over the globe, performing music of the greatest composers of history, and music of great composers still living today.


" Our purpose is to enrich our community by engaging audiences and inspiring a love of music through exciting live symphony performances, innovative programming, and educational outreach."  We offer opportunities for the community to experience the very best in music, “right in their own back-yards.”  No long drives to downtown Los Angeles, no expensive parking. Arts and music for our community, in our community.


The Southland Symphony Orchestra is a volunteer, community orchestra, providing fantastic opportunities for qualified musicians to experience and perform live music of the highest quality. We welcome musicians of all ages and from all walks of life: Students and senior citizens, professionals and amateurs: Hobbyist, Professional, Retired…. All are welcome.   


Are you a musician, and would you like a chance to participate? Musician Auditions: The Southland Symphony holds ongoing auditions for NEW musician members. Interested musicians should contact us immediately for an audition, by calling (909) 235-9776 or emailing: auditions@southlandsymphony.com



The Southland Symphony needs YOUR help - Why do we need YOUR support?


The Southland Symphony Orchestra relies significantly on the generosity of individuals, businesses, foundations and government entities. While “concert door donations” are of tremendous help, they cover less than one-third of the Orchestra's operating budget. Your support will help the organization achieve a balanced budget each year.

 We are a recognized 501c3 organization. You can view our determination letter here: CLICK

Every great city deserves a great orchestra, and as one of Ontario's key cultural treasures, it is critical that the SSO continues to provide the community with its core group of world-class musicians. The SSO provides audiences of all ages with high quality artistic performances, while bringing internationally renowned guest artists to the Inland Empire. In addition, the Orchestra is looking to the future, planning to serve more than 10,000+ students annually through inspirational and educational programs and outreach initiatives.


Our  season is well underway - and for it to continue we need to raise funds.  Each concert requires music, guest artists, recording equipment, musicians, lights, music stands, instruments, refreshments, program printing, etc., etc., etc ....


You can make a difference today by supporting the Southland Symphony Orchestra with a gift of any size.  We invite you to make a donation which will help to sustain the SSO as YOUR Orchestra, while enhancing the Orchestra's impact through critical arts education offerings for area youth. Please support us - help us keep the music flowing, make a donation today. Thank You.
