About Me

The most important title I have is Father.

I am an Israeli, a Jew, an IDF veteran, a lifelong martial artist, a teacher, a writer, and the founder of Krav Maga Experts.

I started Krav Maga in Israel when I was six. In 2001, I joined the IDF Paratroopers Brigade and later trained in dignitary protection and counterterrorism. I became a Krav Maga instructor and instructor trainer and have spent more than two decades teaching people how to protect themselves and others.

Krav Maga is the foundation of my work and has shaped the way I think about preparation, responsibility, and decision-making.

I still train. Along with Krav Maga, I train MMA, Brazilian Jiu-Jitsu, and boxing. Becoming an instructor did not end my education. I want my ideas tested, and I want to keep finding the gaps in what I know.

Today my work includes teaching, writing, speaking, instructor development, corporate training, Krav Talk, and my forthcoming book, Hard to Beat.

The subjects I keep returning to are Jewish identity, courage, leadership, responsibility, personal safety, and what people do when something important depends on their decisions.

How you protect what's entrusted to you is the truer measure of strength. Training here builds the calm ability to do it.

What Shaped Me

I grew up in Israel, where safety, service, identity, and responsibility were part of ordinary life.

Military service gave those subjects practical consequences. Teaching gave them another kind of weight. When people trust you to teach them self-defense, you are responsible for the technique, the student, the training environment, and the judgment being developed with the physical skill.

Fatherhood made that responsibility personal in a different way.

I cannot prepare my children for every problem they will face. I can help them develop judgment, boundaries, courage, resilience, and enough independence to make decisions when I am not beside them.

That is one reason Father remains the title I value most.

What I Study Through Self-Defense

Self-defense gives me a practical way to study human behavior.

I am interested in what people notice before something goes wrong, what fear does to judgment, why some people act while others freeze, how pressure changes performance, when force becomes justified, and what changes when another person depends on your decisions.

The same questions appear in leadership, parenting, business, teaching, and public life.

That is why my work extends far beyond techniques.

The Core of My Being

01

Jewish Identity

I am Israeli. I am Jewish. I am an IDF veteran.

Those identities are part of my family, my history, and my writing.

Since October 7, I have been raising Jewish and Israeli children in New York while watching them encounter arguments about Israel, antisemitism, and Jewish identity before they have enough history to understand much of what they hear.

That changes my responsibility as a father.

I want my children to understand where they come from, recognize hostility without seeing enemies everywhere, remain confident in their identity, and have enough knowledge to think for themselves when other people tell them what being Israeli or Jewish should mean.

I write and speak about Jewish identity because I am living these questions inside my own family and community.

02

Courage

Courage has become closely connected to those questions.

Fear changes judgment and behavior. Courage requires recognizing the fear and still deciding according to what the situation requires.

For Jews today, that can become very practical.

  • Do you wear a Star of David when you know someone may react to it?
  • Do you say you are Israeli when you know the conversation may change?
  • Do you challenge something you believe is wrong when silence would be easier?
  • Do you teach your children to remain visible when they are beginning to understand that visibility may carry a cost?

Courage can require physical action. It can also require speaking, holding a boundary, accepting a consequence, or protecting someone when doing so costs you comfort or approval.

It still requires judgment. Recklessness does not become courage simply because fear is present.

I am interested in the moment when a person understands the risk and still has to decide what responsibility requires.

03

Leadership

I have led soldiers, instructors, employees, students, and a business.

Those environments are different, but each eventually puts someone in a position where a decision has to be made with incomplete information.

People watch what a leader prepares for, what they tolerate, what they ignore, and whether they accept responsibility for decisions that belong to them.

Teaching shaped another part of my view of leadership.

A teacher can give someone an answer. A stronger education gives them enough understanding to make their own decision later.

Parents, instructors, coaches, and leaders should be developing people who can eventually function without waiting for permission.

04

Personal Safety

Personal safety has been my profession for more than two decades.

I teach people to recognize when a situation is changing, understand distance and position, establish boundaries, use the environment, make decisions under stress, escape when possible, and use physical force when circumstances require it.

Self-defense starts before physical contact. Earlier recognition creates more options.

When physical action becomes necessary, timing, judgment, legality, restraint, and understanding the actual problem matter alongside technique.

Training should give people more useful choices.

05

Still a Student

Krav Maga remains my primary system.

I also train MMA, Brazilian Jiu-Jitsu, and boxing.

Boxing sharpens distance, timing, movement, and striking. BJJ gives me another way to study control, leverage, position, and resistance. MMA forces striking and grappling to work together against someone actively trying to stop you.

Krav Maga brings those skills back to a different objective: personal safety, where the situation may involve surprise, weapons, multiple attackers, another person to protect, or the need to escape.

I keep training because I want what I teach to keep developing.

Building Krav Maga Experts

I founded Krav Maga Experts in New York City to teach self-defense as a complete skill.

Students train striking, grappling, groundwork, weapons defense, awareness, boundaries, decision-making, and performance under pressure.

Over the years, I have taught civilians, children, instructors, first responders, companies, universities, schools, and community organizations. KME has also expanded beyond New York, with branches in Boise and France.

The school remains the place where I test and develop these ideas every day.

Teaching Instructors

Instructor education is one of the parts of my work I take most seriously because one instructor can influence thousands of students during a career.

I have trained and certified instructors and previously served as U.S. Director and instructor course trainer for Master Gabi Noah's organization.

I teach instructors to understand the reasoning behind techniques, diagnose problems, adapt training, introduce resistance responsibly, develop judgment, and explain principles clearly enough that students can eventually make decisions on their own.

Teaching creates a responsibility to keep learning.

Invite Me to Teach

My teaching is not limited to Krav Maga Experts.

I travel to gyms, martial arts academies, universities, instructor groups, schools, and training organizations for workshops, seminars, courses, and instructor development.

A host does not need to teach Krav Maga.

Possible subjects include:

  • Krav Maga seminars
  • Weapons defense and knife defense
  • Ground fighting and BJJ applied to self-defense
  • Striking for self-defense
  • Protecting another person
  • Multiple attackers
  • Decision-making and performance under pressure
  • Fighting skills applied to personal safety
  • Instructor development
  • Instructor certification

These are starting points. A workshop or course can also be built around a specific problem, audience, skill set, or question your students and instructors want to study.

The format can be a single workshop, a weekend seminar, a multi-session course, private instructor training, or a longer development program.

I start by understanding who is in the room and what the host wants them to leave knowing or able to do.

Invite Me to Speak

I speak about subjects I have spent years teaching, studying, writing about, and living.

01

Courage and Leadership

Fear, responsibility, and action when doing the right thing carries a cost, and making decisions with incomplete information while developing independent people who accept responsibility for their own choices.

02

Jewish Identity and Courage

Israel, antisemitism, Jewish visibility, history, self-protection, and raising confident Jewish children during a period of growing hostility.

03

Personal Safety

Threat recognition, boundaries, situational awareness, violence prevention, decision-making under pressure, and the use of force.

04

Performance Under Pressure

What martial arts and self-defense reveal about fear, learning, failure, resilience, attention, and decision-making.

These are examples of where my experience can contribute. I also build talks around the audience, event, and questions the organizers want to explore.

I speak at conferences, companies, schools, universities, Jewish organizations, community events, panels, podcasts, and private programs.

Work With Me on Organizational Safety

I work with companies, schools, universities, nonprofits, community organizations, and professional groups.

Programs may address workplace violence prevention, situational awareness, de-escalation, personal safety, travel safety, active threats, physical self-defense, leadership, and decision-making under pressure.

I start with the people and the environment.

Hospital staff, executives, students, teachers, retail employees, and people traveling internationally face different problems. Their training should reflect those differences.

Writing and Public Work

Writing gives me room to stay with questions longer than I can during a class.

I write about courage, leadership, fatherhood, self-defense, force, Jewish identity, Israel, antisemitism, children, community, resilience, and human behavior under pressure.

My work has appeared in The Times of Israel, JNS, The Algemeiner, eJewishPhilanthropy, Aish, and American Thinker.

I also publish through the Krav Maga Experts Blog and my Substack.
