Linda DeSanders and her team of Red Cross-certified instructors coach all levels of swimmers—from 3-month-old “baby dolphins” to teenage competitors. The school is serious about safety, but classes for little ones use songs and toys to create a fun atmosphere. Eight group lessons are $215. Private and semiprivate lessons are available on-site or in the client’s pool. Classes are held in various Dallas locations; call for details. 214-361-4542.
