The roots of National Taekwon-Do Academy Inc. date back to the founding of Taekwon-Do as a Martial  art.   In 1972 School Director / President Earl Weiss began his Taekwon-Do training at American Taekwon-Do Institute under Gregg  Youstra  (who retired as ITF Dan # A-6-13). That School was affiliated with ITF Taekwon-Do Pioneer Han Cha Kyo (Who received ITF Dan # K-8-6).  In 1974 the USTF was founded after a testing was conducted at that school. In 1988 upon the retirement of Sa Bum Nim Youstra, Earl Weiss as senior rank formed National Taekwon-Do Academy Inc.  The School has been both the State and Regional Headquarters for the USTF, representing the ITF as well with  ITF Plaque #5103 continuously since 1990. The school is a member of the United States Taekwon-Do Federation.
