Mi Yama Ryu Kempo JuJutsu / Krav Maga  & Ninshido is the core of our Raven Self Defense curriculum and is our signature Martial Art and Self-Defense system. Raven Self-Defense is a blending of the most practical self-defense into a kick, strike, throw, submit, stick, knife, gun, and survival system. RSD is developed from physical techniques and the mindset of the Samurai & Israeli Warriors to the culture of the dangerous streets of modern, urban America. In effect, we have created one of the few self-defense curricula suited for today's streets. Raven Self-Defense has been taught to thousands of civilians and has been used in troubled youth homes, The Guardian Angels, the United States Navy, as well as taught at police and law enforcement academies across the United States.

Raven Self Defense Academy is not a gym, where individuals train in relative isolation; it is a community. Our instructors work hard to get to know each individual and work to accommodate their personal needs.

We are based in the philosophy of developing the Body, Mind, and Spirit through the traditional Martial Arts Way of Life. This includes the development of physical and cerebral self-defense skills, improvement of stamina and physical health, development of concentration and focus, and expansion of self-control and social awareness.

RAVEN is a university of the martial arts, and we maintain the highest standards of respect, courtesy, and professional training. Our students train with each other, and not against each other. From our students, we expect kindness, integrity, respect, loyalty, humility, and a warrior mentality.

The primary focus of our curriculum is the continual improvement and development of all of our students. We believe that on our training mat there is never an opponent but many training partners. We all train and sweat together for the shared goal of improving everyone’s ability. We train as a family and believe the strength of the RAVEN Ohana (family) is each individual member and the strength of each member is the 

RAVEN Ohana 

Age, gender, current fitness level, or athleticism are not factors in starting martial arts training. 

The purpose of  Mi Yama Ryu Kempo  JuJutsu lies not in victory or defeat but in the perfection of one’s character. Martial Arts and the Modern Day Samurai philosophy enhances one's self-worth and develops character and maturity. This is instilled in all students, helping them find self-confidence and discipline, putting them on a pathway to higher achievement outside the dojo.

Our Classes

Our group classes are dynamic, challenging, interesting, and most of all...FUN! Classes normally begin with some type of functional warm-up. During this time, students engage in aerobically based movement that features the same body mechanics required in martial arts training. ​ Once students are adequately “loosened up,” group class will focus on one or two specific aspects of the RAVEN curriculum. These include:

Speed & Agility

Speed and agility training may include kickboxing drills, work with weapons, or specific evasive movement.

Striking and Kicking

Striking and kicking practice and drills are essential elements of all martial arts. Specific drills using the focus pads, kicking shields, or other pieces of equipment will help coordination, build upper and lower body strength and greatly increase stamina. Students may work on previously learned skills, or be introduced to a new method of kicking or striking based on our wide range of inclusive styles.

Self-Defense & Counter Aggression

Students learn the essential skills necessary to deal with both physical and verbal aggression. The focus is real-world self-defense training. You will learn proven techniques that include defenses against punches, kicks, grabs, chokes, and weapons. Self-defense is an integral part of a group class and teaches students the movements and reactions necessary to overcome any aggressive situation.

Cerebral Self Defense

A martial art consists of more than physical movement, it is also a mental mindset. Students are taught how to evaluate aggressive behavior. They also learn to deal with overpowering personalities and to become empowered by their knowledge of self-defense. This aspect of training directly transfers to daily life when dealing with any stressful situation or overpowering circumstances.


All of the Martial Arts taught in our dynamic group classes are also available on a private or semi-private basis. Whether your interest is in private one-on-one instruction, training with a friend, family training, or a group of friends who want to learn specific skills - we can create a training program for you! RSDA instructors are certified to teach Mi Yama Ryu Kemp JuJutsu.
