Darren Levine — Krav Maga in North America
The Los Angeles attorney who brought Krav Maga to the United States in 1981 and built the dominant US federation.
Darren Levine first trained with Imi Lichtenfeld in Israel in 1981 as part of a US delegation sponsored by the Jewish Federation of Los Angeles. Imi taught the group for six weeks; Levine was offered direct certification to bring the system to the United States.
The first US classes
Levine returned to LA in late 1981 and began teaching classes at the Heschel Day School and the Wise Brandeis Center. By the mid-1980s the program had grown enough to become Krav Maga Worldwide — initially as the Krav Maga Association of America, then formalized in 1997.
Law enforcement and federal contracts
Levine's most consequential decision was to pursue federal law-enforcement contracts. By the late 1990s KMW was training the FBI Hostage Rescue Team, the US Marshals, the Federal Air Marshal Service, and several federal protection details. This produced a US-specific variant of the curriculum — more emphasis on weapon retention, less on multiple-attacker scenarios.
The franchise model
KMW pioneered the Krav Maga gym franchise. By the 2000s there were hundreds of licensed KMW affiliates across the US. This made KMW the federation most US students will encounter first, though the franchise model has also drawn criticism for quality variance between affiliates.
Technical signature
KMW's curriculum is structurally similar to IKMF / KMG but uses different grading (Level 1–5 + Expert + Master), different naming, and a somewhat more aggressive default response in early levels. The technical material at expert level is broadly equivalent across federations.
