The North Brandywine Swim League celebrated it's 50th anniversary in 2010. Founded in 1961 as a group of swim clubs in Brandywine 100 coming together for some fun and swimming competition, the NBSL has continued to grow. We remain decicated to the same mission from 1961: providing a safe, fun and low-pressure competitive environment where area families can come together to enjoy the summer with their children and friends. It's our estimation that almost 55,000 swimmers have jumped in our pools representing the league. We are busy preparing for our next summer of fun! Here's to the next 50 years!
