Ippon is home to many instructors, with a combined total of 110 years of mat experience. Our instructors have a passion for passing on their knowledge, and they find joy in helping eager students fulfill their aspirations in the martial arts. As you will learn from reading their bios, our instructors have varied backgrounds. Their experiences span across many different dojos, martial arts, and methods of teaching. This diversity is a great asset, as it is difficult to find such a unique blend of expertise.
