The Washington D.C. chapter of the St. Peter's College Old Boys' Union was first established during the late 1980s. Starting off as an informal gathering of schoolmates, the group over time evolved into a formal organization, which now enables like-minded alumni and their families to gather and participate in community events and activities that support the advancement of their alma mater.
The SPCOBUWDC formalized in 2003, has grown in membership, accomplishments, and has won the respect of not only of the Sri Lankan community in the Washington D.C. area, but also the greater local communities and is now a 501-C approved charity in the USA.
