I am a certified swimming coach,instructor and lifeguard.I have been teaching swim lessons for 10 years.I have been a swimming competitor for more than 20 years and now I am a master swimmer.Recently I won a third place 100m.fly in USMS National,Short Course Swimming Championships.I take teaching lessons seriously and I think it is crucial for everyone to have the opportunity to learn how to swim. There is no specific age to start, only that the desire to learn is present :)
