Seido Karate

Seido Karate was founded by Kaicho (Chairman) Tadashi Nakamura. Kaicho Nakamura came to New York City in 1966 to bring the Kyokushin Karate style of Master Masutatsu Oyama to the United States, but eventually began to find differences in philosophy with his longtime mentor. In 1976 Kaicho Nakamura respectfully withdrew from the Kyokushin-kai and began to build Seido Juku, "the school of the Sincere Way".

Jun Shihan Tom Swiss

Jun Shihan ("Associate Master") Tom Swiss began his Seido Karate training in 1985. He holds the rank of sixth degree black belt in that art. After receiving black belt ranking in October 1995, he spent several years as an assistant instructor at the Howard County Seido program before starting the Catonsville Seido Karate program in January of 2002.

While his primary interests in karate training are personal development and self-defense, he has also competed in tournaments ranging from regional to international. In 2007 he had the rare opportunity to visit Japan for three months and to teach karate there. In 2012 and 2017 he was part of special Seido Karate demonstrations at temples in Japan.
