Everyone who trains in Seibukan Jujutsu walks away after each class a slightly better person - they've learned a new technique, or broken a new barrier to their "personal best," or discovered something new about themselves.  Others should come in and train for that alone - the opportunity to grow and develop after each class.~Alex Jukl

Training in Seibukan Jujutsu has been a huge part of my life over the past 3 years. It has given me confidence, and it has given me new friends. Seibukan Jujutsu has taught me so much not just in the Dojo but outside of it as well. It has taught me to be disciplined in everything I do. Also, to have a dream and to work as hard as I can to reach that dream and make it a reality. ~Mike Crisler

It has been a very positive experience. Especially for women, it is a great way to learn some self-defense skills while becoming physically confident.~Nicola Leisses

Seibukan Jujutsu has kept me grounded and helped give me clear goals and perspective in life.~Elliot Newman

I was drawn in by the notion of a martial art for "modern times" - one that focused less on brute force and more on intelligently using the tools available.~Alex Jukl

From the first class I attended, it has always made me feel at home. It relaxes me and allows me to learn about myself and grow. It has also helped me through some difficult times and decisions, and reminds me to focus on what's really important in life. With Seibukan Jujutsu, it seems that it is always pushing you to grow more as a person, and that's what I always take away from it. ~Zoey Ryan

My experience with Seibukan Jujutsu has been extraordinary - one of the things I like best about it is that it provides an entirely new lens with which to view and respond to the world. Obstacles become challenges, and failures become learning experiences. It also teaches you different perspectives on how to approach situations, and how to deal with others' energy - this art helps me to function much better than I did before. ~Alex Jukl


The people, both teacher and students alike, are personally interested in the growth of one another, and create a safe and welcoming environment. The right balance between challenge and support.~Nicola Leisses


The dojo is my home away from home in Santa Cruz. The group itself is like a family to me, and we always have an amazing time together. I've made some incredible friends through jujutsu, and it's always nice to come back to those people throughout the weeks and know that they'll be there for you.~Zoey Ryan

The experience at the dojo is perfect - it's become the new standard by which I will judge any martial arts class.  I'm continually drawn back not only by the prospect of learning new techniques and honing my skills, but by the people as well - everyone is helpful, positive, and wants you to succeed.  There is no ego - just shared encouragement and growth.  That kind of community is difficult to discover nowadays.~Alex Jukl

The dojo is well maintained. I keep coming back because of the excellent instruction I am receiving. I learn from everyone, not just the sensei. The black belts do a very good job teaching. ~Timothy Leung

This is a good group of people to train with, and an elegant and effective martial arts system. I find that everyone in the dojo has a great attitude and is very kind and helpful.  I recognize that there are many great things for me to learn there.~Leonardo Gonzalez


Renshi Rosas is one of the best Martial Artists I have ever seen. I have trained in different arts over the years, but no one is better to train under than José Miguel Rosas. His passion, knowledge and expertise is superior bar none, and the way he teaches and presents himself is what keeps me coming back. He truly cares for all his students not only on a professional level, but on a personal level as well. ~Mike Crisler

Renshi Rosas has a calming spirit which allows even the most daunting challenge to seen obtainable. He shows intense interest in helping his students grow within the art of Seibukan Jujutsu and in their personal lives.
~Nicola Leisses

Renshi Rosas is the most dedicated Teacher I have ever known. He expects excellence from his students and always follows through so that they gain the skills to deliver that excellence.~Elliot Newman
Renshi Rosas is amazingly patient with all of us, and his never-ending encouragement helps all of us grow. He's always available to talk if we need someone to confide in, and has built an amazing support system.~Zoey Ryan

Renshi Rosas is for me an amazing leader, martial artist, and instructor. He is impeccable on and off the mat. I would follow him into battle if it were the old days.~David W. Christie D.C.

Renshi Rosas is an amazing instructor. He cares a lot about each student and he wants to make sure all of them succeed. He learned from the founder of the martial art and he does an impeccable job at passing on the art with great integrity and respect. ~Giovanni Vaz Del Bello
An incredible teacher who motivates his students to develop their character as well as their martial skills. He has great patience, perseverance, as well as a great sense of humor….wonderfully complements his high level of martial accomplishments.~Jon Mates

Renshi Rosas is encouraging, accepting, and generous - he is always willing and available to help a student to overcome an obstacle or to aid them in reaching their goals.  He is the best teacher you could ask for - patient, understanding, and receptive to questions and thoughts.  With Renshi Rosas, students excel.~Alex Jukl



I always enjoy the moments before and after class, where we hang out and catch up on each others' weeks. Working with the black belts is always a challenge, but they also inevitably inspire the want to get further along in the art, and provide the necessary encouragement and training for the kohai to do so. It's also always great to see belt tests being completed. Whether for a Kyu or Dan level belt, it gives everyone in the dojo a sense of pride and accomplishment to see one of our peers progressing. ~Zoey Ryan

One of the most memorable (and recurring) memories I have is the patience and understanding of the higher students in teaching me techniques I was having difficulty with.  In Seibukan Jujutsu, you're typically doing things you've never done before, and it can be extremely daunting; even worse, it can be impossible to learn anything without a helping hand.  My most memorable moment is every time one of the superior students took time to help me understand or re-conceptualize how to do something, and then stuck with me until I got it right.  The positive, generous, encouraging attitude I see from the students is what makes these moments memorable to me.~Alex Jukl

The most memorable moment for me was having the honor to participate in Sensei Rosas Demonstration for Hachidan. It was a very special moment for me, the Santa Cruz Dojo, and the art of Seibukan Jujutsu. It was so powerful to be at Honbu Dojo with all the different Dojos there. It was an amazing feeling.~Mike Crisler
