DYK 88% of child drownings occur with at least one adult present? Take the pledge to put your phone away when near the water this summer and always assign a water watcher who is undistracted by phones, conversations, reading, or alcohol.

While active supervision is your best defense, giving your child the skills to navigate the water is just as vital. Equip them for a safer summer: https://brnw.ch/21x3qFg

Happy YMCA Founder’s Day! 🎉

182 years ago, a small group of young people in London sparked an idea that would grow into a global movement - a place for belonging, wellness, and community for all.

Today, the Y is still where people find connection, purpose, and the chance to become their best selves.

From 1844 to 2026 (and beyond) there’s no place like this place. We’re a family. A support system. A force for good.

Share how the Y has shaped your life. Tag us and share your Y story to celebrate 182 years of community!
