Mr. Brian Duffy began his training in Kenpo Karate in 1970, and in 1972 began training directly under Gary Swan, President of the National Chinese Kenpo Karate Association. In 1978, Mr. Duffy became its Vice-President.

Nine years later, Mr. Duffy began to study directly under Senior Grandmaster Edmund K. Parker and later joined the IKKA. Only two years later, in 1989, Mr. Parker promoted Mr. Duffy to Fifth Degree Black Belt and began involving Mr. Duffy in projects for the IKKA such as the development of a standardized children's curriculum and revision of the IKKA belt charts and manuals. Mr. Duffy has since authored the restructured 16-technique curriculum currently in use and widely accepted by Kenpo schools all over the world, and has also sponsored the 1994 Texas Training Camp which saw the birth of the AKSC. He has also developed the Kenpo Long Staff Seminar and Curriculum incorporating Kenpo techniques and principles.

His resume reads for a good long time. Brian Duffy was inducted into the World Martial Arts Hall of Fame and elevated to the American Kenpo Senior Council Executive Committee both in 1997. He has also recently been promoted to 7th Degree Black Belt by the AKSC. Since 1972, Mr. Duffy has competed in over 124 Tournaments and won 157 trophies, including being a five-time champion of Mr. Parker's Long Beach International Karate Championships, and currently owns the oldest full-time professional school of martial arts in Austin, TX. Other things that he has been involved with are the Amateur Organization of Karate Board of Directors, Amateur Organization of Karate Rules Committee Chairman, AOK Top 5 Weapons and Forms Competitor, United Martial Arts Association Top 5 Forms and Weapons Competitor, nomination for Instructor of the Year for Inside Kung Fu. Who's Who in Karate, Regional Director for the IKKA, and more mentions for being one of the top forms and weapons competitors in magazines than I have space to write out. For a complete list, visit his biography on the AKSC website.

He operates the American Kenpo Federation from his school in Austin, TX and maintains a website for the organization.
