The OSO is proudly celebrating its 25 anniversary this year! To mark this milestone, we are thrilled to host the first-ever Ball on Barnes Green on Saturday, 6th September. The evening will begin with a drinks reception outside the OSO, followed by a move into a stunning marquee for a delicious celebration dinner, live music, and dancing. It promises to be a truly unforgettable event!

 

As part of our mission to raise £25k in 2025, the evening will also include raffles and auctions, offering you the chance to win amazing adventures and gifts while supporting the continued development of the OSO.

 

Dress code: Black Tie.
