I have been a lifelong practitioner of martial arts, starting at the age of three under the instruction of my mother and father, Jill and Bob Leiker. Throughout my career, I have competed in hundreds of tournaments around the United States, Canada, Mexico and Europe. I am an 11-time WKA, WSKF and NBL professional world champion and a 3-time SKIL amateur world champion. I currently compete on the NASKA and WKA world sport karate circuits and teach at AmeriKick Martial Arts in Overland Park, KS.

On July 9-10 at the Coronado Springs Resort in Orlando, FL I captured wins at the US Open, the LARGEST martial arts tournament in the WORLD! Over 3,000 competitors filled the arena and my divisions were as tough as they come. Over 40 countries were represented and the tournament was televised by ESPN 2. These were major wins and locked up my WORLD CHAMPIONSHIP for the year in one of my two major categories. One more win in two weeks at the US Capitol Classics in Washington D.C. and I will lock up my other division as well, making me a 13-time WORLD CHAMPION! - Posted about 1 month ago

I totally agree! I would love to come to your event, and hopefully it isn't the same time as my show in Chicago, or my trip to FL. Just let me know when you'll be here and I will try to make it if I'm around. :) - Posted 4 months ago
