Our Swimmer Profile

All types of swimmers belong to OA Masters, ranging from novice to Olympic Champion (Karen Moe Humphreys) and an English Channel Swimmer (Ranie Pearce). We may have different aquatic backgrounds but we share a love of the water and of swimming for fun and fitness. Some of us compete in swim meets, open water swims and triathlons although most do not. Many joined OAM after extended absences from swimming while some are just now learning to swim competitively. All are welcome! And if you are not sure, try us out for free for a week and see what you think. You just have to be 19 or older to join.
