• About Martial Arts at the Lake

    Martial Arts at the Lake is owned and operated by a family that has been studying and training in the martial arts for over 20 years.

    Few words can describe the experience my children and I have had while training with the Rojas brothers at Martial Arts at the Lake. Their professionalism is topnotch and a refreshing experience. Their ability to build rapport with parents and young children is astounding. Not only do they have the energy needed to excite the kids into learning, but they also have the ability to work with little ones and encourage greatness through their skills and teachings. My son and daughter, just 4 and 6 years old, have made such growth in areas such as discipline and and respect that I have seen it carry over into our home! I have been nothing but impressed with the Rojas brothers and their dojo! Thank you for helping me shape my children into individuals with character and integrity.

    A thankful mom,

    I love teaching Taekwondo. I grew up watching all the Martial Arts movies. I’ve got so much passion for the activity! I especially enjoy teaching the Kids Classes because kids have so much energy that everyday is refreshing. Don’t get me wrong! Sharing the art with Adults is great too! Adults are so great at understanding the fine details of technique. I know firsthand that Taekwondo is the perfect activity for everyone! Nate Rojas
