Mr. Chittim was the first member of the United States Karate Association, established by Robert Tries, and held many positions in this national organization. While serving as regional director, Mr. Chittim was remember for the following quotation found in the constitution of the United States Karate Association. "Let me stress to the membership that they keep an open mind and choose from the various styles of karate the things that work for them. Fight rough and tough so as to show the matchless American fighting ability. The daydreamers and romantics are those who feel they must copy some other country's fighting spirit."
