See For Yourself
GSD is not a gym. We are a 501c3 not for profit organization created by self defense experts and students focused on helping communities seeking self-defense training with quality experts, at an optimal location.
Created in 2019, we have helped launch programs in Brooklyn, New York City, Long Island and Fort Lauderdale.
​GSD's classes provides free services to qualified groups that seek to remove all barriers to life-saving training to make it accessible, affordable and sustainable.

The People Have Spoken!


SARA, 31


ARON, 36

After a few weeks, I felt so empowered. I can't believe the difference in such a short time.

I was attacked 2 months ago.

I never reported it.

I was praying for this program.

There is nothing like this. Real-life scenarios that make me feel confident to protect my family.


GSD is honored to train the largest group of Orthodox Jews in the U.S. 

For over three years and steps from Chabad World Headquarters, GSD trains 100+ students each week in situational awareness and more.
But we are humbled at what this community has taught us.


Stronger <--> Together

We have partnerships with hundreds of organizations to share our model of success and coordinate our efforts. Let us help you.

As random acts of violence and outright antisemitism skyrocket with barely any reaction from the broader public, we must become our own first responders.
