He was a co-founder of the IKMA (Israeli Krav Maga Association) in 1977. In 1994, upon Imi Lichtenfeld's retirement, he became the Grandmaster and president of the Israeli Krav Maga Association. He was granted an 8th dan white and red belt by Imi Lichtenfeld (also known as Imi Sde-Or), the founder of Krav Maga. Today Gidon now holds a 10th dan red belt which is the highest degree in his style of Krav Maga.
After the Six-Day War Gidon resumed his competitive boxing and decided to learn more about the Krav Maga principles he had learned in the military. In 1977, along with Lichtenfeld and other top instructors, Gidon co-founded the Israeli Krav Maga Association (IKMA) which he now heads as president. The IKMA board voted to add (Gidon System) to the IKMA's name to ensure people understand the specific brand and quality of Israeli krav maga that is taught. In 1994 Gidon was elected as IKMA president and opened his current gym and the main training center for the IKMA, located on Ben Zion Street in Netanya, Israel. In 1995 Lichtenfeld nominated Gidon as the top authority to grant 1st dan (level) Krav Maga black belts and up. In an IKMA ceremony Lichtenfeld awarded Gidon an 8th dan (one of only two Lichtenfeld ever awarded) designating Gidon as the highest ranking Krav Maga instructor.
The IKMA (Israeli Krav Maga Association) was the original association founded by Imi Lichtenfeld, he appointed Haim as its president when Imi retired. There are a lot of videos and pictures to testify this fact, as well as the moment when Master Gidon earned 8th Dan.
Lichtenfeld approved of Gidon's adding extensive groundwork, modified weapons defenses and other additions/improvements to the Krav Maga system. As president of the IKMA he has taught defensive tactics for the last thirty years to Israel's security and military agencies. Haim received a commendation directly from the Office of the Israeli Prime Minister thanking him for his teaching contributions to Israel's security organizations.
