Elliot Freeman (Founder and C.E.O. of Defensive Tactics Technologies) has trained in the martial art of Aikido under Master Stephen Seagal for nearly 30 years. He carries many other black belts in various fighting styles, but Seagal's Aikido (Tenshin) is the basis for much of DTT's techniques. Mr. Seagal himself has been a supporter of Freeman's DTT program since its conception, and has been an integral part of its development. Graduates of Freeman's DTT program carry the stamp of Freeman's and Seagal's approval, and the right to claim the honor of having participated in their program.
