[4][2][7] Malcewicz subsequently entered into an agreement with Dan Kolov that gave him exclusive rights to promote wrestling events in a dozen towns and cities in Northern California and Nevada.

Malcewicz built a strong tag team division, with the top stars including brothers Ben and Mike Sharpe, who held the championship on 18 occasions.

Malcewicz and Karasick built a strong relationship with Rikidōzan and his Japan Wrestling Association, with the promotions trading wrestlers across the Pacific.

[12][5] In May 1956, the Sharpe Brothers briefly lost the San Francisco version of the NWA World Tag Team Championship to Koukichi Endo and Rikidōzan during a tour of Japan.

Crossover athletes appearing with NWA San Francisco during the 1950s included strongman Doug Hepburn[14] and National Football League players Art Michalik, Gene Lipscomb, Leo Nomellini,[3] and Cy Williams.
