TACFLOW Lead Development Team


Our team is made up of like minded individuals who believe it is not only our duty, but our privilege, to give back to our communities. Every member of the TACFLOW Development Team is chosen not only for their expertise, but also for their commitment to excellence. All Tacflow Instructors go through a thorough vetting process, including an audition phase, followed by a mentoring program by one or more of the Lead Developers listed on this page. There are many exceptional operators out there, but the ability to develop programs where instructors can easily translate that knowledge and pass it on to others is a valuable skill in itself. Diverse backgrounds allows us to custom tailor courses of almost any curriculum. The TACFLOW teaching methodology is more than a system, it is a way of translating information in a manageable, intelligent way.

tacflow lead instructors Rigo Durazo

Rigo Durazo

Director of Training

Rigo Durazo is the founder of the Tacflow Combatives Program and was the Director of Training for Craft International until it ceased doing business in 2015. He has over 20 years’ experience in the global security field, specializing in low signature protection in some of the most remote regions of the world. He worked as a business liaison into Mexico and Latin America as a security and anti-kidnapping specialist.
The Tacflow Combatives Program was developed as a collaboration of ancient technology fusing or flowing with modern weaponry. Rigo has spent years translating this information to operators including SWAT officers, Secret Service, DEA, Undercover/ Narcotics officers, Human Trafficking Units, Patrol, and Military personnel.
Rigo understands the limitations of the time most operators have to ingrain new technologies, and builds the foundations and fundamentals based on their shooting education and behavioral science. He stresses that it is not the technology that will save you; it will be your combative mindset. This technology is just more tools to add to your toolbox of answers.
Today Rigo Durazo oversees all of Tacflow’s Training Program offerings and curriculum. He is the senior instructor for SEACA SYSTEMA (South East Asia Combative Arts SYSTEMA) a synthesis of Kali systems and several Silat systems.
