Safety & Empowerment for Women of Color
A new FREE online program for Women of Color

8/20 & 8/27, 6:30-8:30pm EST, 2-session course

This two-session class will focus on self-defense situations specific to communities of color and will teach principles of boundary setting, strategies against microaggressions & social disparities, and how to navigate challenging conversations through role-play. The class will primarily be led by instructors of color.

To register for this free class, please email instructor Adriana Li at ali@impactboston.org with your name, city/state, and why you would like to take this course. Upon receipt of your registration, you will be sent the Zoom link and further details.

* This class is intended for women-identified people of color, only, to learn in an affinity space together.


Find your courage and use it to make the world around you safer.

At IMPACT we believe everyone has the right to be safe and the ability to protect themselves. Our self-defense programs give people the skills to stay calm and focused in unsafe situations. Our abuse prevention programs give schools, disability service organizations, and communities the tools to develop policies and expectations that keep everyone safe.

IMPACT offers:

  • Self-defense classes that are open to the public.
  • Customized workshops for schools, disability service organizations, community groups, businesses, human service agencies, and domestic violence and sexual assault survivors that cover topics in:
    • Abuse prevention
    • Self-defense
    • Assertive communication
    • Conflict de-escalation

Personal and social change are possible when people experience the strength of their bodies and the power of their voices.

Working for Safer Communities

Many communities are experiencing harassment and violence in the current political climate. Many others are feeling a sense of urgency to speak up and show solidarity and support for neighbors, friends, and even strangers.

At IMPACT we believe that keeping ourselves safe and advocating for others go hand in hand. We are committed to giving community groups and individuals the tools to safely intervene when someone else is at risk. This means having the skills to protect your own safety and manage your own stress response in the moment of violence or harassment.

In the past few months we’ve taught bystander skills in mosques, Unitarian churches, community centers, and our own training center. We’re committed to reaching individuals and communities with these necessary tools.
