Since its founding in 1968, USSD has been established as the premiere Martial Arts and Self Defense organization throughout North America. From its early beginnings as a small studio in the outskirts of Boston, USSD has grown to over 70 locations nationwide and counting. Like the well-nurtured bonsai, the roots of the United Studios family run deep built on a foundation of traditional values with a modern day approach to self-defense and personal development. For over 40 years, United Studios has pioneered martial arts training, providing professional instruction to Men, Women & Children of all ages.
