My dad always had an interest in Martial Arts, He studied, Judo, Aikido, and found a great love for Kenpo in the mid 1970s at Close’s Kenpo Karate prior to him joining the Army. (At Close’s he was a classmate of a young Jef Dix.)  He discontinued his training for many years until January 1991, when he saw a newspaper add from San Rafael Kenpo Karate advertising a  “2 for 1” special.  Realizing this was the Kenpo School he had originally trained in, he returned bringing my younger brother and me with him.

Sifu Ian Derammelaere, 3rd Degree Black Belt

Ian BB Pic

I was born in Belo Horizonte, Brazil, son of a Belgium father and South African mother, and moved to the United States when I was three years old, settling in Novato, California. Throughout my school years I was very involved in a variety of sports and outdoor activities such as soccer, baseball, running, and tennis, and was always interested in health and fitness.

I got my first taste of martial arts at age 12, when I attended Ito’s White Tiger karate school in Novato. I trained under Mr. Ito for three years and obtained my advanced purple belt. After leaving Ito’s White Tiger I took a year off to focus on various sports, until a flyer for Marin Kenpo Karate caught my eye and renewed my interest for the martial arts. I will never forget the first day I entered the school, as it was the day that Jef and Marjorie Dix gave birth to their daughter Kylen. More

Mike Daly, 1st Degree Black Belt

Mike Daly Combat Kenpo

I was born in SF in 1965 and moved to Marin in 1973, right next door to Sifu Rob Guidi. Although a few years apart, we grew up together, attended the same high school and played  a lot of basketball throughout our lives. In 2009, Sifu Guidi asked me if I wanted to take up martial arts. That is where it all started.  I have had the honor and privilege to train with almost all of the black belts in Combat Kenpo as well as all the current students at various levels over the years.  I want to especially thank Sifu Milton Davis, Sifu Rob Guidi, Sifu Andrew Guidi and Sifu Mike Dougherty who have all spent countless hours helping me become a martial artist. The ongoing dedication to Combat Kenpo by all of these warriors is impressive.
Lastly, to simply be allowed to train under Professor Jefrie Dix is an honor and a privilege. Obtaining any belt and diploma with Professor Jefrie Dix’ and Senior Grandmaster Rick Alemany’s signatures speaks volumes about high standards. To be included with this group is one of my greatest life achievements.


Laura Spaulding, 1st Degree Black Belt

Laura Spaulding Combat Kenpo High Desert Combat Kenpo

I was first introduced to martial arts when my son Eric started taking classes from Sifu Terry Neill almost 10 years ago. I sat in the back of the class every week watching and becoming more and more interested. I met Sifu Jefrie Dix when he would come and guest-teach the class on occasion when Sifu Neill was out of town. Fast-forward to August of 2010 when Sifu Dix held a weekend Combat Kenpo Karate Camp at his home and allowed Eric, who was 12 y/o at the time, to participate.  When I dropped him off for the first day of camp, Sifu Dix introduced us to his wonderful family and all of his students who had come up from California for the camp. Everyone was incredibly kind and welcomed us warmly. 
While there, Sifu Dix offered to show me the dojo which was still under a bit of construction. When we walked inside, I knew instantly that I was supposed to be there. I had my first lesson in October of 2010 and was hooked. Undeniably, the beginning of my journey was more difficult than I care to admit. To say that I am not a natural athlete is a colossal understatement; but, I embraced the Combat Kenpo principle “The test is in the training” and I haven’t stopped. Through the challenges, Sifu Dix stuck with me and believed in me until I believed in myself. His patience, encouragement, and dedication to his students’ practice is unsurpassed and I am a better martial artist, and person, because of this. I have also been fortunate to get to know and train with his other Combat Kenpo students from Oregon and California and I admire them all tremendously. I feel lucky and proud to be part of this family.
Five and a half years, hundreds of lessons and thousands of hours of training later, here we are. Receiving my Black Belt from Sifu Dix is one of the greatest accomplishments of my life.  I am both honored and humbled to be one of his students and look forward to training with him for as long as I can.
