If it concerns a decision made at a water polo tournament or a swim meet, you must wait 48 hours after the event to expect a response. Coaches will not address your concern until that time has passed.
If it is another concern, you can email email@example.com and ask for a meeting during office hours.
If you are not satisfied with the response, you can contact the Club President.
If you are not satisfied with the response of the Club President, you can contact the Club Ombudsman.
