The Punahou 5th grader recently took home first place in two events at the King of the Groms 12 and under skate competition in California.
Now he's heading to Minneapolis on Wednesday to compete in the national competition.
"There's lots of pressure but I just got to stay focused and don't get distracted", says Reynolds.
He does that with the help of his father, Matt, a lifelong surfer, who wanted his son to take up surfing too.
"He didn't really, wasn't really having much fun, I felt like I was forcing him to surf, but as we came to the skate park he felt like he found his calling", said Matt.
"It's pretty similar, except skateboarding is surfing on streets", said Heimana.
Like any sport... There's always the risk of injury. Heimana has already suffered a broken foot and two minor concussions, but that isn't stopping him from constantly trying new tricks.
"I am trying to improve on getting better at rails, skating vert", said Heimana.
And with the Olympic Committee possibly adding skateboarding to the list of sports in 2012, Heimana has his sights set on bringing home Olympic Gold in the future.
