I hold a Senior Full instructor Rank in Jeet Kune Do , Jeet Kune Do Concepts, and Filipino Martial arts (the equivalent of Master rank in traditional arts) as well as black belt ranks in several other arts. More importantly though, I have two wonderful children and an equally wonderful wife. The responsibilities of becoming a husband and father changed the way I viewed the martial arts. Even though I worked in clinical psychology, fatherhood allowed me to intimately understand a parent’s need to provide a safe and nurturing environments and experiences for their children. It allowed me to rethink what the martial arts could offer the entire family.

My progression began as a toddler; I used to introduce myself as THE Sugar Ray Leonard.  My father said that if I would agree to be “Jack” again, he would allow me to learn how to box; we had a deal.  My martial arts journey began with boxing on June 4th, 1980. My interest led me to explore and study many martial arts . These initially included  Boxing,  Karate, Wing Chun, Five- Animal Kung Fu, Ninjutsu, and Hapkido. Though I earned a black belt in two of these arts in the 1980’s, I now find child-black belts suspicious (which is why I offer my students a path to junior black belt until a certain age). Later, (after a older school-mate punched my braces through my cheek) my main focus became Muay Thai, Western Boxing, and by 1993, shoot-fighting and MMA.  Wanting to better my full-contact skill set,  I chose to study JKD, FMA, no-gi jiu-jitsu, and MMA extensively from the 1990’s to present.

I became assistant instructor to my PFS mentor, Full instructor Joe Freyman in 1998. I earned my first independent instructor rank for JKD and Kali under Joe in 2000 ( and continue to train with him every time I visit the east coast). In 1999, I met  the JKD / FMA legend Paul Vunak. Over the course of the years, I earned my Senior Full-Instructorship certifications under Paul in: Jeet Kune Do, JKD concepts, Filipino Martial Arts, Rapid Assault Tactics, Law Enforcement continuum, and Edged Weapons Tactics (2008). Though I studied some No - Gi BJJ before my time with PFS, Paul told me that I had to work on this range. I learned much of my ground basics during my time with Joe and Paul and with my training partner Hank Hayes (inventor of no lie blades/ NLB tactical). To augment this I studied with Jiujitsu and Judo with Master Rick Rogers. I earned my 4th degree Black belt in traditional Jiu-jitsu and Judo under Master Rogers in 2009. In 2010, I fulfilled my long time bucket- list goal and trained Muay Thai in Thailand (primarily with Kru Hlukhin from KYN gym). Currently, I have resumed my training with BJJ Professor Roy Harris to study Brazilian Jiu Jitsu (including BJJ over 40).

Though I focus more on self-protection than competition, I have held MMA licenses through the Colorado's State Athletic commission and currently hold my boxing coach certifications through USA Boxing (national governing federation for Olympic boxing). Currently, my continued education in martial arts includes an intensive study of BJJ (gi and no-gi) under grappling pioneer, Roy Harris. This includes studying his BJJ over 40 program.  I also continue to develop my JKD, FMA, and Silat with Joe Freyman, through my own research and by attending Guro Dan Inosanto’s seminar workshops.

Outside of martial arts, my credentials include my 15 year career in clinical psychology as a violence prevention specialist at the acute level of care and in lockdown facilities; I am trained in four separate violence/crisis prevention curriculums. 

In my classes, I help martial artists of all ages develop their attributes in the five crucial areas of martial arts:  technical, athletic, tactical, contextual (scenario) and especially the emotional. I prioritize increasing my students’ ability to reliably navigate all levels of conflict for self-protection in an uncontrolled environment.

In addition to teaching martial arts, I hold a Master’s degree (philosophy and theory). Recently, I have transitioned from a full-time martial artist, to a full-time teacher of rhetoric, composition, and research writing at the University of Colorado. When I am not teaching martial arts or writing, I spend my time with my two wonderful children and my lovely wife.

Women's Self-Defense Director

I am the creator and director of our K.A.T. Power women’s self-defense program. I have trained JKD with chief instructor Jack since 2006, and at the instructor-level since 2014. As a woman and mother, my concern has always been real self-defense against assailants who would likely be bigger, stronger, and have serious, bad intent. My focus, then, led me to tailor our martial arts programs toward specific dangerous scenarios.  I am also interested in the intersection between martial arts, personal/existential power, and community. It is my conviction that the development of personal power through the martial arts directly leads to the betterment of our communities. As we gain awareness and learn to act effectively in the face of oppression (physical, mental, or social), we transform ourselves and the world around us. 

In my classes, I emphasize attribute development through drills and exercises that increase strength, coordination, timing and more. As well, we explore the emotional and mental dimension of real self-defense. Because these concepts and skills are worth learning early, I tailor them for the hands and ears of younger students, too.

In addition to teaching the martial arts, I am an instructor of philosophy at Arapahoe Community College, and a mom to two young children. When I am not teaching, I am outside somewhere with my kids and husband, Jack.
