💍🧡 Our bride-to-be, Sasa, just crushed her last class before “I do”! We’ll miss her smile and energy in the studio, but we can’t wait to have her back in a month as a newlywed ✨ Cheers to love, laughter, and lots more splats in this next chapter!

This morning, our OTF Union Station community came together at the St. Jude’s 5K Walk/Run 🧡 We were proud to sponsor the letter “O” and even prouder to walk alongside so many others in the fight against childhood cancer.
Coach Lindsay and her family, Victoria, and Kirsten joined the crowd — but the impact was truly made by the greater community standing shoulder to shoulder for such an important cause. ✨
Thank you to everyone who showed up, donated, and supported. Together, we’re stronger. 💪
