²ÝÁñÉçÇø School Review - Established 2003
The Bishop's School Photo - Athletics are more than healthy competition at Bishop's. They are a way of life. League titles are terrific (and we have plenty), but we cheer just as loudly for that first at-bat and the last runner in, because we want you in the game. Any game. And not just for now, but for good.
