My 13YO daughter and I spent the morning under the instruction of Heitor. Never having even touched a surfboard before - he was able to get both of us up & riding the gentle Waikiki waves several times over. He made pleasant chit chat with us, making our experience even more personable.
Tip: make sure to consume some calories before your session! (Having an 8am lesson, I did not.) I'm an endurance athlete, but was fried from the paddling and sun by the end of it all...
