A Rich History

RDCA (Robert Duzoglou’s Combative Arts) is the result of Sensei Robert’s lifelong passion and affinity for the martial arts. With over 45 years experience and Black Belts in 5 styles, his goal has always been to provide an elite education in self defense, covering a range of disciplines and skill sets.

Character Development

Utilizing the martial arts as a platform for character development, we constantly engage our students in discussion about subjects such as discipline, respect, persistence and compassion. Constantly reinforcing our pillars of Love, Hope, Faith and Charity in and outside of the dojo.

“I have been studying and training Martial Arts for over 25 years. I lived in japan for 3 years while serving in the Marine Corp. I have fought MMA on a professional level, and the techniques I’ve learned from RDCA work! They are battle tested and combat proven… RDCA IS THE REAL DEAL! Osu!”

“Sensei, you have such a balance between loving and encouraging – and firmness and demanding. We truly appreciate you and what (and how) you are teaching the kids.”


“Congratulations on your award of Excellence from the Key Biscayne Chamber of Commerce. The business community is very proud of you and your accomplishments and the recognition that you bring to our island.”


“When I started at RDCA, I learned that even though you can have fun, you should always have respect and discipline. I learned that my biggest dreams could come true if I tried and tried and practiced. I have learned that my body is like a big rock. I have to polish it, take care of it, and work with it, and in time it will be a diamond.”


“There is nothing like RDCA here in Honduras. We’ve looked for another school, but our experiences have fallen well short of our expectations; mostly due to the fact that the schools here do not have the same sense of family or spiritual completeness that you have so graciously shared with us over the years.”


“Just know that you are always in our thoughts and in our hearts, and we wish you only the best. May God bless you and your family. We love you, and will never forget everything that you have done for us.”
