YMCA's are always a good choice. The Town North YMCA is located in north dallas on northaven road. The provide swim lessons for younger kids and once they get swimming in general down they can go on to ethier swim team, or cub swim team. Cub swim team is basicly learning basics of the strokes were as swim team is working on more detailed parts of the strokes and and speed. You can look its up on the YMCA website or google. Oh and no matter what the front desk says there IS a swim team for the town north Y. Hope i helped
