At my kids' gym, the gym owner used to coach, but doesn't anymore. There is a girls' team director, a head optional coach and a head compulsory coach for the girls. Boys' team had a director and two other coaches who are senior coaches, but I don't think anyone has the "head coach" title. There are always multiple rec classes and team workouts going on at once and they do have some kind of rotation schedule that determines who gets which equipment when.
