“GSD builds confidence and teaches life-skills for the challenges of today.“. - Det. Marc Black, NYPD (ret)

The founders of GSD are grandchildren of Holocaust survivors and former Krav Maga instructors of the IDF -- we knew what was coming - that's why we're prepared to help.

Founded in 2019, GSD trains 200+ students every week in 7 classes at 3 locations. Students pay to train with GSD.

Following the horrible massacre on October 7 in Israel, antisemitic incidents have become rampant across the country and especially on college campuses. We continue to receive dozens of requests for self defense training and therefore, are expanding our model.

GSD focuses on proactive approaches to safety and security with training in: situational awareness, threat detection, de-escalation, Krav Maga, scenario-based risks, emergency first aid and more. We work to empower communities to mitigate threats before they increase.

Scaling Up

GSD is building a training center in midtown NYC launching in November/December. Funds are needed for our location, equipment, scholarships and community outreach programs that will work to deter antisemitic activity.

Being reactive is not enough; we must be proactive. Please learn more about GSD and our locations here.

This is not a drill.

Never again is operational.
