    The Training

    Owner/Instructor Lisa Thew

    Our PREVENT training is derived from the R.A.D. Systems of Self-Defense, and if utilized, can help prevent us from becoming targeted in the first place. 

    The DEFEND techniques are rooted in R.A.D. and influenced by Hapkido. The techniques are specifically designed to utilize the innate strengths of the female body, and can be used by women of all ages, shapes, and abilities. 

    "The moment a student comes to understand and unlock their own power is absolutely electric. Every time, with every student. It happens without fail, and it's the most beautiful thing on Earth."


    Lisa Thew, Founder, Diamond Defense
