I have over 15 years of experience in martial arts and have achieved a 2nd Degree Black Belt in Hwa Rang Do. A two-time World Hwa Rang Do Grappling Grand Champion, I have extensive knowledge in nearly every element of martial arts, including joint manipulation, sparring, grappling, striking, and weapon fighting.

My specialties include women's self-defense, bully prevention, professional full-contact training, sparring coaching, and tournament training. Not only that, but I'm also experienced in enhancing your conditioning and muscle endurance. Whether you're aiming for weight loss, lean muscle, energy restoration, or just a healthier lifestyle, my personalized plans will get you there. With my guidance, you'll receive in-depth nutrition coaching that will optimize your overall health.

I typically give private lessons, but I'm happy to teach classes of up to 30 people across all ages from 3-year-olds to seniors over 70. Looking forward to helping you to achieve all of your fitness and martial arts goals!

Instructor Day has proven to be an exceptional teacher and mentor, displaying extensive knowledge in his field. Though I was hesitant about embarking on my martial arts journey, I found his instruction to be enjoyable and beneficial right from the start. The classes are stimulating as they focus on mastering techniques rather than replicating unorganized movements. I strongly urge others to partake in his classes.

In just a few weeks of working with Instructor Day, I am amazed at the incredible transformation I have undergone. My entire outlook on movement has changed, and I have gained an extraordinary amount of knowledge. Although I leave each class feeling exhausted, I also feel exhilarated. What sets Instructor Day apart is their ability to customize the experience to fit my body and needs. They patiently answer any questions I have and introduce new techniques at an engaging, manageable pace.

My instructor, Day, is an amazing teacher who provides me with exceptional guidance in achieving my fitness objectives. I have been under his guidance since November and have managed to shed 25 pounds through his proficient advice on fitness and healthy eating habits. The opportunity to engage in workout sessions amidst the fresh open air and stunning front yard of his residence has provided me with a unique, personalized lesson encounter that surpasses all others. My progress has exceeded my expectations and I enthusiastically recommend Instructor Day to anyone seeking to develop their physical strength and self-confidence.
