About Our Dojo

View Page

The Orange City dojo (a Honbu dojo) was first opened in 1983, by Grand Master Chester Holubecki, a 10th Degree Black Belt, when he moved to Orange City from his home in Massachusetts.

When Grand Master Holubecki returned to Massachusetts in 1996, the dojo was operated at two other locations before being reopened at 1900 North Volusia Avenue, as a “Black Belt only” dojo by local attorney, Sensei and Master John B. Crowther (Hachidan—8th degree Black Belt), in July 1998, through the generosity of Ms. Mary Parker Sizemore, herself an Isshinryu Black Belt (Nidan—2nd degree Black Belt).

In January 1999, the dojo was converted into a “full enrollment” dojo, where both Black Belts and Color Belts can train. Through the efforts of Sensei and Mrs. Crowther, the students, and many contributors and volunteers, the dojo moved to its present location at 130 May Street, on January 15, 2008.

The dojo is affiliated with the Isshinryu Network, an association of Isshinryu dojos located throughout the United States and Puerto Rico. Each year students from the dojo travel to various Championships to participate as competitors, judges and referees. In 1995, the dojo sponsored the American Okinawan Karate Association (A.O.K.A.) World Championships when they were held in Daytona Beach.

—The dojo was honored in 1999, when two of its members were recognized by the A.O.K.A. Hall of Fame, at the 25th Annual World Championships held in Philadelphia.  Sensei Crowther was the recipient of the Outstanding Male Black Belt Award, and Howard Savage, 1st degree Brown Belt, received the Outstanding Male Student Award. 

—In 2000, Sensei Crowther was selected as a Finalist for the A.O.K.A.’s Instructor of the Year Award.

—In 2003, Mr. Steven Hyde, an 18 year-old Shodan (1st degree Black Belt), was the recipient of the A.O.K.A.’s Outstanding Male Youth Black Belt Award.
