About CCS

Cornerstone Combat Sports is dedicated to building martial artists from the ground up through skill-based and goal-oriented training.

The name "Cornerstone Combat Sports" is in reference to Coach Brandon's faith in Jesus as a lifelong Christian.

"Praise to the Lord, my rock, who trains my hands for war, my fingers for battle." ~Psalm 144:1

The MISSION

Thinking optimistically, the grand vision is to have a dedicated facility for hosting larger group sessions and private training in an environment tailored for martial arts/combat sports within the next 5 to 8 years.

The VISION

Meet Your Coach

Brandon Tiehen

Coach & Private Trainer (Founder)

With over a decade of collective martial arts experience, Brandon built his foundation in boxing and wrestling before fully committing to the path of striking. What began as exploration evolved into disciplined, consistent training in Muay Thai, Dutch-style and freestyle kickboxing, and boxing. Today, he continues to train alongside world champion fighters and high-level competitors, sharpening his craft in elite, competitive environments.

Beyond his own development, Brandon has served as a Head Instructor at three academy locations within one of the largest martial arts franchise systems in the world. As a striking specialist, he has worked with over 500 students—and counting—instilling fundamentals that build confidence, resilience, and real capability. From day-one beginners to seasoned martial artists refining their edge, he develops athletes with structure, precision, and practical skill that holds up in sparring, competition, and real-world self-defense situations.

Location

Real estate is expensive, so in the meantime let's meet in a public space near you (i.e. park, gym, etc.), or locally in Lynnwood! Proper training is about the how, not the where.

Location

Determined upon booking.
