My Lake Gaston neighbor and 2009 World Champion Adam Fields runs an awesome wakeboard school here on Lake Gaston in North Carolina. You can check out the website at afwake.com and also check him out on Facebook via AFWake and Adam Fields Wakeboard school.
I can say, you'll be hard pressed to find a more patient and knowledgeable coach. He has students from all across the U.S and around the world every year. I will also tell you, I've seen him coach all skill levels with the same passion and enthusiasm, give him a look, I think you'll like what you see.
