Lehi Jujitsu was established on Historic Lehi Main Street on September 1, 2010, and is dedicated to the preservation and promulgation of the Danzan Ryu system of Jujitsu. The traditional name of the school in Japanese is Sanyu Kai (Interpreted as School of the Mountain Spring).

About Us

Danzan Ryu Jujitsu is a traditional Japanese martial art. Training begins with basic stretching and strengthening exercises. Next, students learn rolls and falls that allow them to be thrown safely. The system is arranged into eleven lists of techniques, which teach the basics of balance, leverage and inertia. The first five lists are taught below Black Belt level: Yawara (basic holds and escapes), Nage (basic throwing arts), Shime (grappling arts), Oku (advanced combination arts) and Goshin Jitsu (self-defense techniques). The remaining six lists, which are primarily taught to advanced students and Black belts, include advanced combination techniques, defenses against gun, knife, staff and sword, demonstration arts, iron fan and Yawara stick arts, kicks, strikes and a system of resuscitation and restorative massage techniques.

Keith started his martial journey at the age of 6 with Isshin Ryu Karate and Tae Kwon Do; however, he really didn’t fully apply himself to the martial ways until the age of 14. He studied Danzan Ryu Jujitsu and Shorin Ryu Karate from Sensei Jim Kelton of the Kodenkan Yudanshakai in Long Beach, CA achieving the rank of Gokyu in both arts before leaving to serve in the Navy. There he studied Judo, earning the rank of Nikyu, while also studying Escrima under Guro Timothy Kashino, founder of the Cadenilla Eskrima Group.

After a break in service, Keith enlisted in the US Army as an Infantryman where he certified as a Level 2 Modern Army Combatives Program instructor (utilizing parts of Wrestling, Gracie Jujitsu and Muay Thai), teaching and certifying countless US and foreign service members in hand-to-hand as well as tactical combat. After leaving Active Duty he joined the Utah Army National Guard, and in 2021 restarted his journey in Danzan Ryu with Sensei Duane Sheely, founder of the Sanyu Kai and Warrior Mountain Academy. While studying DZR Jujitsu, Keith also studies Muso Jikiden Enshin Ryu Iaido under Sensei Jason Hankins and Sensei Dick Beckstead of the Zen Bu Kan.

As his military unit's senior Combatives instructor, Keith has re-introduced an older Army Combatives curriculum to the current that was originally based off of DZR Jujitsu while adding more combat focus to the way soldiers are trained.

Keith also assists Sensei Sheely in the women’s self defense program, and Brigette Swensen in overseeing our youth program, and he shares the responsibility for the development and advancement of the “Junior Warriors.”

When not on the tatami you can find Keith back country camping, shooting, at the gym or cooking a delicious meal.

Discounts available for Warrior Mountain Academy members


I discovered Warrior Mountain Academy a couple of years ago, and it quickly became my favorite Jujitsu School. As someone who has trained in various martial arts schools across the globe, including in Japan, I can confidently say that this school is one of the best.

The teacher provides personalized instruction, which is invaluable in helping me improve my technique. But what sets this school apart is that the teacher doesn't just teach techniques, but also concepts that give me a deeper understanding of the art. Sheely Sensei has a deep respect for tradition, and also teaches how to use the techniques in practical scenarios.

What I appreciate most about this school is that the teacher helps cultivate not just martial skills, but also a mindset that has helped me in various ways throughout my daily life. I highly recommend Warrior Mountain Academy to both beginners and experienced practitioners. It's a fantastic place to learn and grow in Jujitsu.

Throughout multiple styles and lineages, Sheely Sensei is hands down the best martial arts instructor I have ever had the pleasure of learning from. He has a deep knowledge of Jujitsu and blends in other concepts extremely well. This dojo has probably the single most “complete” curriculums you will ever see. From escapes and holds to strikes, throws, ground work, and even basic weapons. This style of Jujitsu has a strong esoteric core and also has healing arts woven into the curriculum. The childrens class is made to be a fun and exciting learning environment and many students eventually transition over to the adult class and continue their martial journeys. If you’re looking for a school that’ll teach you self defense as well as strengthen your mind body and spirit, check this dojo out and become part of the Ohana!

This place is incredible!!!!!
My son started going to Lehi Jujitsu a few years ago and we love it!! Its the perfect mix of Martial art and fun. The dojo is very clean and organized. Sensei Duane is very good with the kids, he's not only so good at teaching jujitsu but he also teaches discipline and respect. Its also very affordable!!!

Larissa Dudley

The sensei is great and works with the kids phenomenally. Nice location right on main street Lehi and, most importantly, the quality program and low cost were why we chose this place over other, more costly, contract required places.

Jonathan Love

Quenton Bennett

Lehi jujitsu's application of danzan ryu jujitsu is simply superb. Sensei Sheely does an excellent job of taking the art's formal teaching and showing how those principles are applied for real life situations.

The art is focused on self defense and you learn control to apply any degree of force necessary for the situation at hand. Whether that's just control or all the way to taking a life is that's what the situation requires.

The esoteric teaching are excellent as professor okazaki says that jujitsu is for "the perfection of character". Coming here will definitely help you mold yourself into the kind of person you want to be. I couldn't recommend it highly enough.

Dan Harper

This is the place to go if you, your child, or even your toddler want martial arts classes. You can learn various disciplines in a fun, structured environment. Sensei Sheely is an excellent teacher. I highly recommend it here 🙂
