Meet Chaz Siangco | Senior Master – Chief Instructor and Owner

We had the good fortune of connecting with Chaz Siangco and we’ve shared our conversation below.

Hi Chaz, can you walk us through the thought-process of starting your business?
My thought process behind starting my own business, Derobio Legacy, was deeply rooted in my passion for preserving and evolving Pulahan-Derobio Eskrima. Growing up, I was fortunate to learn from my great-grandfather, Great Grandmaster Braulio Tomada Pedoy, my father Grandmaster Christopher Siangco and other incredible mentors in my family. I saw firsthand the power of this martial art—not just as a form of combat but as a way to instill discipline, confidence, and adaptability.

My journey to starting Derobio Legacy was never just about opening a business—it was about carrying forward a legacy, honoring my roots, and adapting a centuries-old martial art for the modern world. Growing up, I was immersed in Pulahan-Derobio Eskrima, learning from my great-grandfather, Great Grandmaster Braulio Tomada Pedoy, as well as other esteemed mentors in my family. Their teachings instilled in me not only skill but a deep respect for the art and the warriors who came before me.

As I progressed in my martial arts journey, I also pursued a career in law enforcement, gaining firsthand experience with real-world threats and the limitations of traditional training. I saw a critical need for a system that blended the fluid, strategic movements of Eskrima with the realities of modern self-defense. That realization led me to develop the Accelerated Response Movement (A.R.M) Program, a method designed to break down and refine traditional techniques for practical application in high-risk situations.

For me, Derobio Legacy is more than just a training center—it’s a living, breathing continuation of a warrior tradition. It’s about empowering people, from law enforcement officers to everyday civilians, with the tools they need to protect themselves and others. It’s about preserving the heart of Derobio Eskrima while evolving it for today’s world.

Every student who walks through my doors isn’t just learning a martial art; they’re stepping into a tradition, a mindset, a way of life. Watching them grow, adapt, and embrace this system is the most rewarding part of what I do. This isn’t just a business—it’s a mission, a legacy, and a commitment to ensuring that the spirit of Derobio lives on for generations to come.

Let’s talk shop? Tell us more about your career, what can you share with our community?
My career has been a journey of dedication, resilience, and a deep passion for preserving and evolving the art of Pulahan-Derobio Eskrima. What sets me apart from others is my ability to blend tradition with modern application. While many martial artists focus solely on the historical aspects of their craft, I’ve worked to ensure that Derobio Eskrima remains a living, evolving system—one that is practical and adaptable for today’s world, whether in law enforcement, military operations, or civilian self-defense.

Beyond martial arts, my career extends into public service and mentorship. I currently serve as a Correctional Counselor with the San Diego Probation Department, where I work with individuals navigating the justice system. This role has given me firsthand insight into the importance of rehabilitation, accountability, and second chances. It has reinforced my belief that discipline, structure, and mentorship can change lives, just as they do in martial arts training.

I also have a deep passion for faith and community service. I serve as a high school ministry leader and worship leader at EastLake Church, where I help guide and mentor young people in their spiritual journeys. Music and faith have always been integral parts of my life, and being able to lead worship and inspire the next generation is something I cherish deeply.

One of the things I’m most proud of is the development of the Accelerated Response Movement (A.R.M) Program. This program breaks down traditional techniques and restructures them to meet the demands of modern-day combat situations. It’s been incredibly rewarding to see this system benefit not only martial artists but also professionals in high-risk fields who need effective, real-world self-defense training.

Getting to where I am today was far from easy. There were countless challenges—physical, mental, and professional. Balancing tradition with innovation wasn’t always simple, and stepping outside of conventional teaching methods required confidence in my vision. In the early stages, I faced skepticism from those who believed that traditional martial arts should remain unchanged. But I knew that adaptation was necessary for survival, just as it has always been in the warrior traditions of the Philippines.

To overcome these challenges, I stayed committed to my core principles—respecting the roots of Eskrima while pushing its boundaries. I surrounded myself with mentors, peers, and students who believed in the vision of Derobio Legacy. Most importantly, I never stopped learning. Whether it was through my experiences in law enforcement, working alongside military professionals, mentoring youth in my church, or continuously refining my techniques, I embraced every opportunity for growth.

The biggest lesson I’ve learned along the way is that legacy isn’t just about what you inherit—it’s about what you contribute and pass forward. My goal has never been just to teach martial arts; it has been to equip people with the mindset, skills, and confidence to protect themselves and others. I want the world to know that Derobio Eskrima is more than a fighting system—it’s a philosophy, a way of life, and a connection to something greater than ourselves.

At Derobio Legacy, we don’t just train fighters—we build warriors in mind, body, and spirit. Whether it’s through martial arts, public service, or faith, I am committed to ensuring that the values of discipline, resilience, and empowerment continue to inspire and shape future generations.

Shoutout is all about shouting out others who you feel deserve additional recognition and exposure. Who would you like to shoutout?
Absolutely! I wouldn’t be where I am today without the guidance, support, and wisdom of so many incredible people. First and foremost, I have to give the deepest respect and recognition to my great-grandfather, Great Grandmaster Braulio Tomada Pedoy. His teachings laid the foundation for everything I do. He wasn’t just a master of Pulahan-Derobio Eskrima—he was a visionary who passed down a system that embodies discipline, adaptability, and the warrior spirit. His legacy continues to inspire me every day.

I also want to acknowledge my father, Grandmaster Chris Siangco, and my brothers, who have been by my side throughout this journey. We’ve trained together, pushed each other to grow, and worked tirelessly to refine and expand our family’s martial arts system. Their dedication and passion have fueled my own, and I wouldn’t be the martial artist or instructor I am today without them.

Beyond family, I have to give a huge shoutout to Batikan Eduardo Pedoy, whose mentorship helped shape my understanding of Eskrima and its deeper principles. His knowledge and experience were invaluable, and I’m forever grateful for the time I spent training under him.

Additionally, my career in law enforcement introduced me to some exceptional mentors and colleagues who reinforced the importance of real-world application in combat training. Their insights and experiences helped shape the Accelerated Response Movement (A.R.M) Program, ensuring that what I teach isn’t just theoretical—it’s practical and effective in high-stakes situations.

Lastly, I want to recognize my students and the entire Derobio Legacy community. Teaching is a two-way street, and every student I’ve had the privilege of training has contributed to my growth as an instructor and martial artist. Seeing them apply these teachings, whether in their careers or personal lives, is what drives me to keep pushing forward.

This journey has never been a solo effort. It’s been built on the wisdom of past generations, the support of my family, the camaraderie of my peers, and the passion of my students. To all of them—I am deeply grateful.
