"Coach Demko specializes in teaching his curriculum in a way that is easy to digest for everyone from high level athletes to the average hobbyist. Not only does he know the craft but he understands how to teach it in such a way that the learner will remember but also be able to practically apply later on.

 I would attribute 70% of my current skillset to Coach Demko directly with the remaining skills being attributed to personal preference but learned through Coach Demko’s teaching methods.

I highly recommend Coach Demko to anyone who plans to take their learning seriously because you will learn, grow, and develop skills in his system. From the layman looking to defend themselves to the aspiring world champion Coach Demko will sharpen your skills and prepare you to succeed."
