We build strong people so they can live their own adventure.



Welcome to Bujinkan Taka-Seigi Dojo | San Diego! Our names are Bill and Laura Stegner, we have both studied martial arts for decades and have shared many adventures around the world.

We founded BTSD | San Diego in 2005 with a single goal in mind – a place where good people can come together and become stronger in order to reach personal and fitness goals they never thought possible…

We’re In The Business Of Building Strong People and living a life of adventure…

You see, we know personally that the mind and spirit are more powerful than the limitations of the body. Our involvement in the US military and travels around the world have taught us that life is short, we need to let go of our self-imposed limitations and live each day to the fullest.

We have witnessed some of our students go from being shy and nervous teenagers to leading National Geographic tours into China and becoming staffers in the US Congress. Others have gone from being stiff and tired 50-somethings to doing diving rolls over obstacles their height and getting into sword-fighting!

Here at BTSD | San Diego, we’re here to strengthen you, both by encouraging you and motivating you to find the strength that is inside of you. We're certain that, no matter the challenges you or your family are facing, you’ll overcome those hurdles and find the adventure in your life!


~ Hear what our students have to say ~



The world of martial arts is a mess. Mixed martial arts (MMA), karate, kung-fu, krav-maga, ninjitsu, aikido, kickboxing ... the list goes on and on. We personally went through several arts before we found what we were looking for, Bujinkan. Many of our students did as well.

BTSD | San Diego was started in 2005 with a specific goal in mind - a place where people of good character can come together, train each other, and become stronger than we are - to be able to move through life more powerfully. To accomplish that, we created a place that is free of politics, egos, bad attitudes, and bull shit. The quest is for what will work for you.

Our students come from all walks of life - business owners, students, combat veterans, Ph.D's, computer professionals, special forces, intelligence professionals, etc. They all have one thing in common - they've found what they're looking for in a martial art and in a training hall. From self defense to traditional Japanese martial art disciplines such as kenjutsu (sword) or bojutsu (staff), or looking for more than what they found in the mixed martial arts world, they have found it here.

We have a beautiful training facility of over 7000 sq ft with dedicated areas for our training and classrooms for courses such as music, calligraphy, and language. We are also located next to a wooded area and have access to off-site facilities to extend our training to a more natural setting.

Our training goes from the highly traditional to the completely modern. It is also structured to accommodate people of all skill levels. If you're a little nervous about training, it's ok, we're here to help you through it! Or, if you're looking for hard, rough and tumble training, good, we enjoy and excel at that!

Our dojo is built for working professionals, real people with real lives. Involvement of the whole family is welcome and encouraged.

All people of good character are welcome to join us.
