To A Caring Parent

Hi, my name is Robert Shepherd.

Many people walk through the doors of my school for the first time and think that martial arts is just about punching and kicking. This may surprise you, but there is so much more to it.

Our goal at JSK 5.0 Humboldt Martial Arts & Fitness is to use martial arts as a vehicle to inspire kids to be more confident and focused in their daily activities.

Below, I would like to share with you the most important benefits that children and parents get from our program. Then afterward, I will let our members do the talking and share with you exactly how our program transformed their child’s life.

The Transformation

After Just A Few Weeks Of MArtial Arts, This is What Happens...

Action-Packed Fitness and Exercise.

Action-packed games, activities, and exercises give kids a great workout from head to toe.

They get stronger, healthier and more fit within just a couple weeks. These fun exercises also help maintain a healthy weight!

The best part? The fitness is disguised as FUN! All your child will know is that they’re having a blast. But you and I know they’re also getting the exercise they need.

Self-Defense From Strangers, Bullies, and More.

Make no mistake about it! While our classes are tons of fun, we also cover the "serious" stuff too.

We teach kids about handling strangers... bullies... and more.

However, the first thing we teach is diplomacy. We give your child the tools they need to "talk it out" first. Violence is ALWAYS a last resort!

Powerful Character Development Breeds Discipline, Focus, and Respect.

For thousands of years, martial arts has been one of the best kept secrets for giving kids the skills they need for success in life.

Through inspiring stories and talks, as well as the process of learning the techniques, kids develop amazing traits, like:

Respect, discipline, focus, and goal setting.

I hope your child will never have to use their self-defense skills. But I guarantee these other skills will come in handy EVERY day for the rest of their life.

Fun, Fun, Fun!!!

While kids work hard and train hard in our classes...

They also smile and laugh a LOT, too!

After all, these are kids we’re dealing with here! Our classes are a great place for kids to socialize, make friends, get support, and have a blast.

My son takes classes here and the owner Mr. Shepard is great. He has helped with my son's attitude and determination tremendously. I enjoy being able to watch the kids learn new and hone previously learned techniques. It's pricey, but worth it. The monthly membership doesn't include all the extra gi attire, etc. However, we were introduced by a super discount which seems common with entry level kiddos. I'd love to try adult classes.

Excellent school to attend to begin your journey to martial Arts. Kenpo is a good full contact art that is good for stress relieve and get in shape while learning how to be competent and confident in your ability to defend yourself. Mr. Shepherd is a good instructor who's work shows through his higher ranked students and trickles down all way down to the beginners. All are welcomed at this school. They also have kick boxing and sparring classes too. Would highly recommend and I'm thankful that there is such a good opportunity here in Fortuna.

Two of my five grandchildren attend karate lessons and love every minute! I highly recommend this establishment! I am impressed with their professionalism, kindness and quality program! My other 3 grandsons will attend as soon as they are old enough!

We have 3 girls who have been taking Mr. Shepard's karate class for almost a year, and we have been so impressed by the increase in their ability and their confidence. When one of the girls began, she just stood on the mat, head faced down, too shy to try. Mr. Shepard was patient yet stern with her, and she has grown in leaps and bounds!

My daughter goes to this program. Mr. Shepard is so patient with the kids and is able to firmly, kindly and with respect re-guide their focus and attention span back to the techniques and values of Kenpo. This class has given my daughter a motivation to practice at her skill and practice respect to her parents. I would and do recommend this class to everyone.
