Nasce nel settembre 1980 il Jissen Dojo Karate, sulle ceneri del karate Club Abbiategrasso, e da subito si segnala come una ventata di novità nel nel mondo delle arti marziali lombarde, guidato dall'allora l'istruttore Giorgio Rainoldi giovanissimo karateka milanese. Dopo qualche anno di assestamento, 1985 si iscrive alla Federazione che il CONI ha fortemente voluto per dare una casa ad uno sport ancora troppo frammentato in piccole organizzazioni, ed associava il Karate al Judo ed alla Lotta. Iniziava così un percorso formativo federale che ha fortemente caratterizzato la formazione tecnica e culturale del Maestro Giorgio Rainoldi: l'Università, poi i corsi multimediali del CONI e la specializzazione presso la Scuola dello Sport dell'Acquacetosa a Roma. Una formazione permanente e continua culminata nel 2013 con l'acquisizione della qualifica di Allenatore di 4° livello Europeo. In mezzo a tutto la qualifica di formatore dei quadri tecnici federali, responsabile dei rapporti con la scuola e l'università, per sette anni all'Università Cattolica del Sacro Cta di Milano ha tenuto il corso SIS corso specializzazione di post laurea; dal 2015 allenatore della Nazionale Italiana Giovanile, ed anche da questa avventura che continua tuttora sono arrivate soddisfazioni importanti, con la conquista di titoli continentali e mondiali.
