Coach Nathaniel Beers brings a strong background in athletics and human performance to the Haruki team. A former collegiate pitcher for Kansas Wesleyan University, where he helped secure two championship titles, Nathaniel holds a degree in Health Science from KWU, an Education Certificate from Pacific Lutheran University, and a Personal Trainer Certification. 

He’s passionate about helping athletes of all ages reach their full potential through disciplined training, mindset development, and personalized coaching.

Sensei Jonathan brings a lifetime of martial arts experience, traditional knowledge, and high-level competition expertise to Haruki Karate. A third-degree black belt with Jundokan International, he has trained in Goju-Ryu under his father since early childhood and continues to carry that tradition into his teaching today.

In addition to his role at Haruki, Jonathan leads a martial arts school in the LC Valley, where he continues the tradition he grew up in while developing the next generation of martial artists. A decorated competitor, he has earned multiple WUKF World Championship medals, including gold in kata, as well as numerous national-level medals. He has also helped train multiple World Champions and brings that experience into the dojo as both an instructor and coach.

Jonathan is passionate about helping students deepen their understanding of martial arts, challenge themselves, and discover what they are capable of both in and outside the dojo.
