Welcome to Women's Self Defense Boston, teaching the SEPS (Situation Effective Protection System) Women's Self Defense & Personal Safety Program

Welcome to Women's Self Defense Boston, offering the SEPS (Situation Effective Protection System), women's self-defense program. This is a free course (there are no charges or costs to attend any of our women's self-defense classes) that runs on Saturday mornings at 10 AM in Charlestown. The program is comprehensive, in that it teaches physical solutions to dealing with violence (against armed and unarmed assaults, whilst standing or on the ground etc), including the use of pepper spray - participants get the chance to train with inert units - along with ways to predict, prevent, identify and avoid violence. The program is supported by an online component, so that those who attend have a resource that they can use to review and refresh the material that they learn in class - to visit the SEPS Women's Self Defense Course, please click here. If you are at university/college or know of someone who is, you can visit our women's campus safety website by clicking here.

This course has been offered free in Boston since 2010, and has trained thousands of women in Massachusetts and the surrounding areas, to both avoid and deal with violent assaults. If you would like to book any of our free classes (the program is modular, and modules can be taken out of turn, or as stand-alone classes), please click here.

SEPS, standing for Situation Effective Protection System, is a framework and personal methodology that empowers individuals to understand and make dynamic risk assessments of the situations they find themselves in. The system stays away from giving "safety tips" and "rules" that women should follow to keep themselves safe, as we recognize that the very people we are trying to protect ourselves from, understand these rules and have subtle ways of getting us to break them. We all know that we shouldn't get into a stranger's car, or let a stranger into our home, however sexual predators etc have ways and means to stop us viewing them as strangers, and getting us to believe that our rules don't apply to the specific situation we find ourselves in. The SEPS system empowers individuals to identify, predict and avoid violence by educating them as to the methods that predatory individuals use to gain access to and disarm their targets/victims as to their real and harmful motivations. To book a free class please click here (we require everybody to book their first class, so that we can control the number of people training with us the first time).

Neither do we simply give good advice, such as that we should be more aware of our surroundings, without telling our students what they are actually looking for e.g. what is actually suspicious and harmful and what can be ignored etc. Rather we teach people how to educate themselves so that they can identify the actions and behaviors of aggressive and violent individuals before they are able to reach/gain access to them. We teach both threat recognition as well as effective decision-making. To book a free class please click here.

The aim of the program is to inform and train as many women as possible as to the types of violence they are likely to face and how to predict, identify and avoid it before it happens - and if it does happen how to physically defend themselves, using basic simple techniques. The program is divided into 8 modules/classes, all of which are backed up with an online resource that provides the information taught in the classes as well as a wealth of background information that supports this. This online resource can be accessed by clicking here.

Our program is totally FREE and is open to women and teenage girls 18 and over. We do discuss topics and subjects of a sexual nature e.g. sexual assault and rape and are very direct in the way that we present this material.

we make use of Redman Scenrio Based Training suits, which are protective padded suits that both the instructors and students can wear in order to practice at real or near real force. All our instructor team are qualified and have received the appropriate training to use these suits. Head Instructor, Gershon Ben Keren was certified by "Red One" as a Redman Scenario Based Trainer.

This training is open to all women aged 15 and over however if you are the survivor of abuse or assault, please be aware that we talk frankly, albeit non-sensationally about violence, and practice with physical contact (everything we do is safe and voluntary and you are able to step out of any drill at any time). If you are in doubt about whether you are emotionally ready at this stage to partake in this type of training, please feel free to come down and watch what we do, and/or talk to your mental health care provider.

Self Protect Boston is a program that looks to prepare teens and young women to the types of violence that they are likely to face

Although our regular free women’s self-defense program is open to those aged 15 plus, we recognize that the teens and young women, may find themselves in very specific situations and scenarios, that women who are a little bit older may not, or no longer experience. If you are 15 plus and would like to attend any of our regular free classes, please click here. If you are under 18 we will need a parent/guardian to sign a consent form to allow you to take the class. This can be accessed by clicking here

Teenage girls and younger women, often socialize as part of a larger group, and belong to specific social groups in a way that older women don’t e.g. it is not uncommon for younger women to go out socializing as part of a large group, that may or may not be mixed gender, which as women and their friends get older, tends to lessen; due to work, family, and other commitments. Our Self-Protect program, looks to address the threats and dangers in these specific situations.

The teenage years are also a time when there is immense peer pressure to conform and act and behave in a certain way, in order to fit in. This can often result in relationship abuse, and young girls getting “played” by boyfriends and male friends – they may also be at risk from older predatory males, who can present opportunities to be respected as an adult, and be part of the adult world, which can be extremely flattering and tempting, although it usually involves a darker side to it.

Our program looks to address these issues and threats in a non-sensational and frank manner, highlighting the dangers and methods that certain individuals use, whether it is an abusive boyfriend manipulating their partner to engage in activities and behaviors they’re not comfortable with, or a sexual predator grooming them for abuse.

We run our free Self-Protect seminars throughout the year – please check the calendar page (click here) for these events or sign up for our newsletter to keep up to date with these events (the sign up form is on the right hand bar of this web page under the map of our studio location). If you are a group or organization that works with young women and would like to find out how to bring our training to your members please use the enquiry form below.

Statistics Demonstrate That Women Who Attend College Or University Are More Likely To Be Sexually Assaulted Than Those Who Don't

When applying to colleges and universities, safety on campus is probably one of the last things you think about however with the latest statistics suggesting that 1 in 5 female students are sexually assaulted in their first year, it definitely warrants serious consideration - information regarding crimes and assaults on university campuses is available due to the Clery Act, which requires all educational institutions that receive financial aid, to report their crime statistics.

However even if you do believe you are attending, or going to attend, a “safe” university, it is still important to educate yourself as to the threats and dangers that you are likely to face, and to the ways in which predatory individuals such as rapists, operate and target/gain access to their victims. You may believe that your common sense and judgment skills are enough, but skilled and experienced predators know how to use these things against you. Only by studying their methods, are you able to identify and avoid them. We have created a free online course, which teaches you to do this, along with protecting yourself from other types of crimes and assaults, such as burglaries, thefts and muggings etc. This course is free and can be accessed by clicking here.

If you are about to attend college/university, or are currently enrolled on a college or university course, please check our calendar, for the free seminars that we offer for those who are attending or about to attend. Our calendar can be accessed by clicking here.

The Instructor Team

Gershon Ben Keren's Krav Maga Blog
The Women's Self-Defense Boston Instructor Team is headed up by Gershon Ben Keren, an academic and security professional with over 20 years experience teaching women's self-defense and personal safety.

When you take time to train any form of self-defense and personal safety you want to be sure, that what you're learning is up to date, practical, proven and effective. Many martial arts and self-defense instructors, simply don't have either the knowledge or the experience, to address the specific threats and types of violence that women are likely to encounter. Gershon Ben Keren has been training women as a distinct "at-risk" group for over 20 years, teaching women's self-defense as something that differs greatly from general self-defense.
