David Hakim

David Hakim

David Hakim, Director of the Midwest Academy, began his martial arts training over three decades ago. He is both a practitioner and teacher of the Seizan Ryu Kempo-Jujutsu system who has studied and received teaching sanction under the art's premier master teachers — Roland Roemer and Dan Pauley. David is currently recognized as a "Godan" ("5th-degree black belt") and was one of the youngest teachers to be qualified as a "Shihan" ("Master Teacher") of the art. David also has experience and teaching authority in various Chinese, Japanese, Israeli, Indonesian, Filipino, and Brazilian martial arts, including teaching license in Modern Arnis de Mano (Remy Presas lineage) and Gracie Combatives (Rener Gracie).

David is Program Lead for the Academy's Firearms-Combatives-Program (FCP), a unique kinesiology-based firearms training program. He also brings his own military and law enforcement professional experiences — where he has served those communities as a combat veteran, special operations leader, and senior trainer — to the Academy.

In addition to being known for his pragmatic approach to martial arts and combatives training, David regularly writes, speaks, and conducts personal and leadership development training for a number of groups inside and outside the Academy. His approach to the topic is drawn from a base of formal education, training, and personal experience, including multiple postgraduate master's degrees related to the topic and deeply personal experience recovering from traumatic and catastrophic injury.

David is a member of the Seizan Ryu Advisory Board, an organization headquartered at the Colorado Academy of Martial Arts, which ensures the current and future integrity of Seizan Ryu schools. He is known, both in the martial arts and law enforcement special operations communities, as being a versatile, well-rounded instructor who blends traditional martial training with a practical and progressive approach.

Regular Guest Teachers

Roland S. Roemer

Roland S. Roemer — Colorado Academy of Martial Arts (CAMA)
Founder, Director, Weapons Program Lead Teacher
Roland founded CAMA in 1988 and has been teaching since 1967. He has obtained advanced degrees and teacher accreditation in eight martial arts systems. Additionally, he holds a Master of Arts degree in education.

Advice to Students: Being a martial artist is equally about traits such as emotional resilience, mental toughness, and a passion for constant learning, as it is about physical prowess. If you conduct yourself as a warrior and a scholar, the world will provide you with everything you need, and probably everything you desire. Ultimately, they are the same thing.
