Thank you for finding David Phang as a swim instructor for Jack and Tessa Powers. David is great. He immediately gained their trust and they listen to everything he says. David instructs Jack by working with him on the actual arm movements instead of just talking at him. David helps Tessa with endurance training by not hearing the drama and instead reassuring her that she can do it. The kids really like going to swim lesson. And David knows how to balance the hard work practice with the fun stuff like learning how to dive. David is an excellent instructor and has already increased their desire to spend time at the Y. Thank you.
