Boost In Confidence

Learning new skills and trying out new techniques is challenging! But when you persevere in the face of a challenge, and come out on top, you realize you're stronger and more capable than you ever thought possible!

Realizing this makes you feel more confident. You feel more sure of your ability to handle whatever other challenges life throws your way too. Both kids and adults feel their self-esteem and confidence soar quickly!

“My son already requested we plan his party at Cornerstone again next year!”
“We hosted our son’s fifth birthday party at Cornerstone. He chose the Jedi theme so Max, the instructor, took the kids through an obstacle course, some basic karate, and then taught the kids Jedi moves with light sabers. Max was kind, organized, and kept a party of 15 little kids happy and under control. My son already requested we plan his party at Cornerstone again next year!”

“Every student is allowed to explore the martial arts to as high a degree as they desire - the instructors will push you to your limits in a way that encourages and inspires you.”
“I trained for many years with Master Kloss as an adult eager to find something physically and mentally engaging to help me stay in shape. I found everything I wanted and more with him and his staff in Hockessin. Every student is allowed to explore the martial arts to as high a degree as they desire - the instructors will push you to your limits in a way that encourages and inspires you. I learned a huge amount about myself physically and mentally, and I continue to feel the influence of their work with me even years later. I can't recommend the team at Cornerstone enough! If you have any interest in getting a well rounded training in the martial arts, this is the place to come!”

“For anyone considering martial arts, this is hands down an awesome place. You will learn so much, make new friends, and look great too.”
“I am so happy to be back to the "new" Cornerstone Martial Arts! Ten years ago I received my first black belt at the age of 50 after two accidents that left me pretty "stiff" in my back and neck. Back then, I received two-on-one instruction with my friend, and three years later was jumping around breaking boards and being totally fit and limber, earning that black belt. I've been away for awhile, but am now committed to be healthy and fit once again with all my buddies to help me for my 60th birthday in January! Thanks Master Kloss and Fiona Smith for encouraging me and working with me last night. I feel like I am home!!!! For anyone considering martial arts, this is hands down an awesome place. You will learn so much, make new friends, and look great too. What you learn will carry over into your everyday life. It is life-changing.”
