Empowering Women Through Self-Defense
At Diamond Defense, we believe women, girls, and vulnerable communities deserve a safe space to explore every aspect of personal safety—from prevention and risk awareness to survivor support and physical self-defense.
In a world where violence is too often normalized and women are disproportionately targeted, finding a secure, judgment-free environment for this work is vital. Diamond Defense provides exactly that: a place where women can learn, share, and grow in confidence without fear of intimidation or harm.
Our programs combine prevention strategies, practical defense skills, and access to personal safety tools, supported by a strong community network. Whether at our new Midtown Sacramento studio or through the Diamond Defense podcast, we offer resources, training, and connection to help women protect themselves, support one another, and build lasting empowerment.

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.
