About Us

Ulster Budokai was founded in 1976 by Sensei Mark Roosa, a professional educator who headed the dojo for 40 years, until his retirement in 2016. Our dojo offers instruction in traditional Kodokan Judo to children (ages 6+), adults and special needs students. Our instructors are volunteers who enjoy sharing their knowledge and donating their time, allowing us to provide quality Judo instruction at a minimum fee.

Classes are structured for competitors and non-competitors alike, with instructions in randori, self-defense, and kata. Competition training is available featuring our experienced local, state and national competitors. Advancement in rank is through the Hudson Judo Yudanshakai and the United States Judo Federation (USJF).
