John Mascio


John Mascio Sensei began studying martial arts while an undergraduate at Kent State University in 1982. In graduate school, he studied Isshin Ryu before relocating to Dallas in 1990 and joining the OKCD. John has also explored many other styles of martial arts in an effort to expand his knowledge. John currently holds the rank of Sandan (3rd dan) in Toei Ryu, and Godan (5th dan) in Shorin Ryu and Shudokan Karate. He teaches the Saturday morning 9am class.

John attributes much of his success in life to the discipline and training he has received in the martial arts, as well as the support of his wife and family. He feels incredibly fortunate to have trained under Sensei Smoger, and with all the talented yundansha of the dojo. Over the years, they have become a second family to him and his wife.

Outside of the dojo, he is an IT professional for a large financial institution. John is one of the City of Allen’s Community Emergency Response Team (CERT) trainers; and provides emergency communications assistance for Allen CERT, the Collin County Medical Reserve Corps, and Collin County Amateur Radio Emergency Service. He lives with his wife, Charrie, in a north Dallas suburb.
