His accomplishments include: he was the first to put out a commercial Karate training video with Mr. Parker, he was the Tournament Director of the second International Karate Championships in Long Beach, and co-owner of a pair of Kenpo studios with Mr. Parker. Also, he was one of only twelve people to receive the rank of 7th Degree Black Belt in Ed Parker's American Kenpo, earning this honor in 1981. He continued his training with Mr. Parker until Mr. Parker's passing in 1990. On that same year, Mr. Sullivan founded the I.K.C.A. (International Karate Connection Association) with Vic LeRoux.

The IKCA is a program which allows individuals around the world to study Kenpo via video tape. To earn any rank, you must test via video and send that video to the IKCA, who will then review it and determine if you have earned your rank. The IKCA will send a personalized tape with a series of ideas and corrections that can further improve your training.

Mr. Sullivan is active in promoting Kenpo through his organization and has recently been honored with the 10th Degree Black Belt.
