BEST SWIMMING SCHOOL IN BATANGAS CITY?

May I ask where is the best swimming school in Batangas City? Batangas City lang please. When I speak of the best swimming school, I am talking about coaches with good attitude, healthy environment, and magaling magturo talaga. I need a very good and kind environment because my son has mild autism (very smart) and he is a very kind boy. I would not want a toxic community for him. Thanks in advance!
