Self-Defense Instructor for Women, Girls, and Female-Identified students

I have been teaching self-defense for women, girls, and female identified people since 1990. I hold a black belt in Jujutsu and a brown belt in Judo.  I am a psychotherapist (LMSW) and specialize in treating survivors of violence and have also treated those who commit violence.   I understand the dynamics of sexual assault and other types of violence and work to empower students physically, psychologically, and emotionally to say “NO!” to attacks of all types and “YES!” to a more empowered life.

“This is a great class to take – not just to learn to protect yourself, but to find your inner strength.”
— 12-hour Class student

My preferred format for self-defense instruction is a 12-hour course taught over four three-hour classes. I also can present shorter workshops to suit the needs of a group.

“Heidi is an amazing instructor that teaches you how to stay more safe in different situations and how to stand up for yourself.”

This class will consist of three areas of focus with the following three goals in mind. It is appropriate for all women, girls and female-identified people ages 12 and older.  If a prospective student is under 12, talk to me about them and we can discuss the content in order for you to decide if they are ready for this type of class.

  1. Mental Preparedness:  We discuss and role play the types of scenarios that put people most at risk for sexual assault and other violence.  We work through hesitation and embarrassment and strive to increase assertiveness, self confidence and a sense of personal power.

  2. Verbal Skills:  Participants learn assertive verbal techniques geared towards de-escalating dangerous or uncomfortable situations.  We work vocally to develop a strong voice and assertive, defensive yell.

  3. Physical Defensive Skills:  Students learn and practice physical skills that are selected to be used by a smaller, less strong person towards a larger, stronger attacker.  The skills you will learn have been proven over years of instruction to be effective in attacks, as well as easy to learn and remember.

“You will feel so strong and badass, like you’re radiating ‘don’t f-ing touch me or try me’ vibes.”
