Chris Cohee:

Chris has been training at our academy since 2009 and received his Black Belt (Level 7) in March 2016. Don't let Chris's humble demeanor fool you, he brings a tremendous amount of experience with him from decades of martial arts training. He is an expert at empty hand, stick and knife fighting. We are fortunate to have him at our academy.

Ryan Ruffini:

Ryan began training with us in 2010. He received his Brown Belt (Level 6) in March of 2016 and is an Assistant Instructor with us. Currently he works in the security field and has a background as an emergency response technician.

We'll have to work on getting a better pic of Ryan, but until then this one of him at one of his test's will have to do!



Todd Hendricks:

Todd began training Krav with us in 2010 and is currently a (Level 5) Blue Belt Practitioner & Assistant Instructor at our academy. He was no stranger to martial arts, he has trained for years when he was younger. He was drawn to Krav Maga because of the straight forward approach of dealing with physical encounters. He came to especially appreciate our academy because of the way we introduce how to be an ethical protector and integrate that ethic into everything we do.

Through hard work and training, he is developing into a great instructor, which is no surprise because of his background in teaching. He has a Masters in Education and is the Dean of Academic Affairs at an local middle school. He is married to a wonderful lady and is the father of two beautiful girls. 


Here are a few of his favorite sayings:

- You reap what you sow.
- It is not what you say but how you say it.  Sometimes you need to speak the language that people understand.
- Just keep going, there is no end, you will either continually improve or quit, so keep going!
- It's not how hard you can get hit, but how hard you can get hit and keep moving forward. (Rocky Balboa)




Larry McDonald:

Larry started with us in 2012. He rose through the ranks quickly because he works hard attending class 3x per week and comes to pretty much every seminar. In July of 2016, Larry received his Blue Belt (Level 5) Practitioner and is an Assistant Instructor here. He has a certificate of completion from many of our certification courses including: The Peace Walker Project, Leadership-Conflict Management Course, Essence of Krav Maga Course, Krav Maga 2.25  Dangerous Places Course and Resolution Group International’s Ethical Protectors Course.  He has experience in Aikido and Tang Soo Do and is a Veteran having served in the U.S. Army for 8 years as a Drill Sargent and Tank Commander. He is also a Tactical Firearms Instructor.

Marc Specter:

Marc is a Blue Belt (Level 5) Practitioner and Assistant Instructor with Ronin Krav Maga. He is evolving into a fine instructor and has much to offer students. Having an eye for safe training Marc is both open minded and considerate toward others as he creates a wonderful learning environment. I am honored to have him here at the academy.
