OSCA offers a wide range of programs geared toward adults (16+) of all ages and interests. Be sure to read through the full guide (link above) or visit us at the Firehall at 260 Sunnyside Ave. Fitness classes are offered during weekdays and evenings and include a variety of options like Yoga, Pilates, Kickboxing, and Broadway Workout. If you’re looking for something creative and fun, check out pottery classes, fictional writing classes, and the Firehall Jammers. New in 2026, we’re especially excited about barre workout and ukulele group lessons!
Though we recommend registering for the whole session as programs do fill, many adult classes offer a convenient drop-in option for those who prefer to take it one week at a time.
For purchasing items like pottery clay, summer camp t-shirts and hats, and water bottles, please visit the online store.
