Sensei Jeff

Owner / Head Instructor

Jeff was born and raised right here in Arvada! He started Martial Arts when he was 6 years old after getting in trouble at school for always pretending to be Power Rangers and Ninja Turtles. He started taking Tae Kwon Do with his Dad, and after six years they both achieved 2nd Degree Black Belt. After a hiatus he wanted to learn a new style, so he tried Kempo. He eventually earned his 5th Degree Black Belt and the Title of Master in Kempo. While opening Dojo Source, he began training Jeet Kune Do with Rogue JKD, in all he has over 20 years of training in various styles.

Before the dojo Jeff was a middle school teacher. Having taught math and science for 5 years he started to feel taxed from getting a new group of students each year and feeling like he couldn't help students for longer than a year at a time. It was this desire as well as his experience that gave Jeff his teaching style of impressive patience. Sensei Jeff will always give you a good workout while teaching you all the tricks, flips and more that the martial arts has to offer!

When Jeff isn't at the Dojo he is an avid volleyball player competing with his wife, Emma, and parents.

Sensei Ben


Sensei Ben's love for the martial arts started when he was 7 watching Dragon Ball Z. That initial interest grew into a love and a passion that transformed his life physically and spiritually. Sensei Ben began training Mixed Martial Arts, Boxing, Muay Thai, Brazilian Jiu Jitsu, and Jeet Kune Do, before coming to Kempo. 

He's been training for over 5 years and teaching for almost 2 years. He loves to bring fitness and the martial arts to everyone. The martial arts provide an opportunity to learn discipline and determination, heart and responsibility, self control and self confidence. Sensei Ben is on a lifetime path of martial arts growth and improvement and is thrilled to bring others along that path!

When Ben isn't at the Dojo he is usually going on adventures with his Wife Melissa, His Daughter Nora, and their two dogs!

We have some amazing groups and individuals out there that make the Dojo happen. 

Check them out!

All of our Students

We of course couldn't do any of this without the people and families at the dojo. We are a independent and local business and our students are the only reason we can do what we do. They help create a great atmosphere in the dojo, help us grow, and of course help each other in and out of classes. We couldn't be doing this without each one of you!

Thank you!

We are very excited to have Jack Gialanella partnered with our school. With his exhaustive training and skill set he not only teaches his own students, but is our Jeet Kun Do instructor as well.  His ability to bring 40 years of training in martial arts to harmony with 15 years of experience in clinical psychology working as a counselor (specializing in violence prevention) allow him to bring a rare cohesion to what he teaches and real life application.

A husband, father of two, a professor at CU Denver, it's hard to believe Jack finds the time to train at all, let alone show the dedication he has throughout the years.  He always leads with dedication, love, and excitement  for every aspect of the martial arts.
