The BSHS Community Service Corps (CSC) serves the Shanahan and Chester County communities throughout the school year with various service projects. It is a club that thoroughly embodies "People of God; People for Others," while also being a great way for students to make new friends. One large annual project that they manage each year is The Christmas Child Program in partnership with St. Agnes Parish. Through this program, each homeroom purchases gifts for a child in need, and CSC wraps the gifts and helps with distribution.
The Easter Basket partnership with Partners in Outreach is another main project through which children in need receive special treats and much needed gifts. CSC also visits residents at the local nursing home in Downingtown, St. Martha's Manor, and helps each year with the special performance of Shanahan's musical that is for people with special needs. On Saturdays in the spring and fall, CSC members also assist with the Challenger Soccer League, assisting children with special needs.
Additionally, each month CSC manages a collection among the student body through which homerooms may donate socks, winter clothing, peanut butter and jelly, etc. for The Lord's Pantry in Downingtown.
