ATC has been offering professional martial arts training for almost 20 years. ATC is a Beginner to Master Training level organization that offers top instruction from World Certified Grandmasters, Masters and Instructors.  Grandmaster Spillmann, founder of ATC and Vice President of several organizations, believes ATC is a place of complete learning.  Grandmaster Spillmann told his academy Masters in 2008 that at the end of 2010 he was going to retire so his dedicated Masters could independently operate their own locations and he could focus on the growth of TaeKwonDo, ATC licensed academies, TaeKwonDo International and his family. Master Spillmann is now focused on writing books, producing DVD's, training with his family and working hard to improve his masters and instructors’ understanding of techniques in TaeKwonDo, HapKiDo, Karate and Rocian Gracie Brazilian Jiu-Jitsu and the knowledge need to run a professional academy. Through our annual world class training seminars Grandmaster Spillmann and other top Grandmasters can insure that ATC students are learning from some of the very best, well balanced, professional martial art teachers in the area.

Grandmaster Spillmann over the last 30 years has personally developed many top masters who teach in many cities in the United States and other countries. Those same Masters continue their training through ATC, TaeKwonDo International, USNTF, USATKD, AAU, RGBJJ and Kukkkiwon world Seminars.
