Sosa Sensei began training in the martial arts in 1953.
He started Aikido training in the mid sixties with Isao Takahashi Sensei and Koichi Tohei Sensei, both of whom trained with the Master and founder of Aikido, Morihei Ueshiba.
Mr. Sosa moved from Chicago, Illinois to Dallas, Texas in 1972.
He formed the Southwestern Aikido Institute of which
he was the chief instructor for 23 years. During this time Mr. Sosa
was responsible for much of the spread of Aikido in Texas, the Southwest
and Mexico.
In 1981, Mr. Sosa joined Kobayashi Sensei in Seidokan Aikido, and served as a senior instructor for 14 years. In 1994, he formed the International Aikido Association, which was under his direction up until his passing in June 2002.
More than 100 aikidoka have earned black belt ranks under Mr. Sosa's guidance. His Aikido will continue through his descendants, instructors and students.
