Sensei Krukower
Daniela Krukower was born in Buenos Aires, Argentina. A short time later Daniela’s family moved to Israel where Daniela was introduced to Judo. Israel had two promising female judoka in one category, Einat Yaron and Daniela, only one could represent their country. The girls were rivals, but also friends, so Daniela decided to represent her birth country Argentina in Judo. Daniela excelled in international competition, on the world stage, and in the Olympics. She won Gold at the World Judo Championships in Osaka by defeating an Olympic gold medalist. Daniela became a celebrity in Argentina and proved to be such a Spirited Warrior that the Argentine media called her "Iron Lady". Daniela is an authentic Martial Art MASTER and CHAMPION. She is a beautiful human being who gives back to the international community as an educator in Personal Health, Safety, and Woman’s Self-Defense. DO IT.
