Coach's Responsibility

The prime responsibility of our coaching staff is to help develop each swimmer under their direction to the fullest potential of the swimmers' interests and abilities. There are different parts to this responsibility, but they all revolve around providing interested people with the opportunity to learn to swim fast. First of all, the coach is to provide our swimmers with the best possible stroke work and training for their stage of development. Next, the coach provides incentives for swimmers in an effort to spur on their interest. Finally, the coach must help develop a strong, supportive environment in which all swimmers feel comfortable and can support one another in their efforts to become the best swimmer that they can become.

We are here to support your needs. For all questions related to workouts, meets, events, goal setting, dues, safety, or policy issues, please contact your squad's coach.
