All Martial Arts Schools are NOT Equal

You're a person who looks for excellence. From schools and careers to doctors and healthcare professionals, you're careful about the choices you make in your life. The martial arts school in which you enroll yourself and your family should also be a carefully considered choice.

At Tiger Martial Arts Academy in Chesterton, Indiana, we personally hand-pick and train our elite team of instructors who bring wisdom, experience, creativity, skill, humor, focus, and integrity to each class. Led by Grandmaster Deborah Grimaldi, one of the most distinguished, highly-ranked, and recognized martial artists and martial arts instructors in the country, Tiger Martial Arts Academy's staff guides each student to his or her personal best.

Through commitment, respect, and dedication, our students discover self-respect and respect for others, the artistry in martial arts, and a powerful ally for self-defense. Tiger Martial Arts Academy students know they are part of something special, and know they have achieved a standard of training that is a cut above. We don't give belts away. Our students earn them.

Founded and run by Master Deborah Grimaldi since 1994, Tiger Martial Arts in Chesterton is a Dojang encompassed in the fundamentals of traditional Tae Kwon Do. But that is not all that Tiger Martial Arts has to offer.

While Tae Kwon Do is the backbone of all our instruction, other fighting arts have been adapted and incorporated into our integrated martial arts curriculum.

The various martial art forms include Hapkido, Small Circle Ju Jitsu concepts, Kyu Sho-Jitsu, Olympic Sparring (TKD), boxing, and street self-defense. These art forms have been selected in order to strengthen the attributes of each student. Each art form has its own strengths and weaknesses, and by combining them together we get a better more well-rounded fighter who is able to adapt to various situations whether it be for sport or protection.

Classes are held weekly and offer something for everyone. Tiny Tigers is perfect for young children who wish to learn the basics of martial arts. Students will learn respect for others, discipline, and self-control as they progress through the fundamentals of Tae Kwon Do while exercising and improving balance. Junior classes are the next step for progressive students who wish to continue their education. Junior students will continue to learn Tae Kwon Do forms and drills which will become more intensive as they progress through the belt ranking system.

For those parents or other newcomers who are interested, we also offer adult classes which implement the integrated martial arts styles. Adult classes usually range in age from the late teens on up. Here, Tae Kwon Do will be the main emphasis for basics and the belt ranking system. Within each class will also be instruction on the various other forms from several professional instructors.
