Real Families, Real Results
Voted the top martial arts school in Sumner County. Hear from the students and parents who train with us.
“I have trained for years, in multiple styles, in multiple states, and at multiple gyms. GMA has the best variety of arts available in the Nashville area — frankly, the best I have seen anywhere. All the instructors are top quality. You won’t find better instructors, a more flexible schedule, or this size gym with such great equipment anywhere else in the State of TN.”
“You won’t find a school around here that offers better training, whether it be in TKD, BJJ, CH… most schools nowadays are just black belt farms — they hand out black belts like candy. There aren’t a lot of real schools out there anymore, but GMA is definitely the real deal… and I’m glad that we are a part of it.”
“Grandmaster Spillmann’s skills and knowledge are sought worldwide. His commitment to furthering the martial arts and developing a more peaceful and just world are inspirational. You won’t find a better martial arts school in your area than his!”
“The best family, Instructors and Grand master. I have known them many years. One of the best instruction schools.”
“Outstanding martial arts training. Exceptional leadership. Wonderful with children and special needs students. Highly recommend!”
“The GMA after-school program is well worth every penny. My children love learning TaeKwonDo and Brazilian Jiu-Jitsu. The school focuses on leadership development and building strong character.”
“We love GMA for both classes and the after-school care! The after-school care is organized and consistent which is a must when you are talking child-care of any kind. The staff focus on teaching the children life skills and they reinforce their school work. This program paired with the martial arts classes available make this a perfect service for my family!”
“Great place to start your young kids in taekwondo. Also good for older kids or adults. Have had two kids going there for a few years now and they have stuck with it. It builds character and teaches them responsibility. Plus it’s nice to see your kids moving up belts and breaking boards.”
“With 3 new students at GMA all the instructors do a fantastic job of ensuring that the kids understand what is being taught. They give constant detailed feedback to help the kids advance. I am very happy that we selected GMA in our search for a school.”
“I signed these guys up after mom was just told we were going for a free trial lesson. Now not even a year later they have learned SO MUCH! Not only a sport but team work, respect, drive, and responsibility. The boys absolutely love their Master Andrew Davis.”
“Thank you to GMA and Joanne Blair Spillmann for the encouragement that was spoken to Ruby tonight. She was on the verge of tears and giving up when ma’am sat down with her and spoke words of encouragement to her. Also thank you to Johnathan Biggerstaff for all his help tonight with the kids.”
“My first kickboxing class as a 41 year old! I may not be good at kickboxing but I am trying! I absolutely love it! This is by far the best workout I have gone through! Master Spillmann is so patient and considerate of our aches and pains that he guides us through class with ease!”
“We have been using GMA’s after-school program for years and never had an issue! We love all the instructors and all the special events they do. The kids always come home excited.”
“We love GMA! The afterschool program is great, the jiu jitsu training our son has received has been amazing. Highly recommend.”
“GMA is the most wonderful martial arts training community ever in Tennessee. I’m grateful our family has the chance to be a part of this great community.”
“The boys moved up a belt. They love it. It is good to see them have something that teaches them responsibility, respect and confidence. When an instructor comes to you and tells you that you have awesome boys — it makes you see that you are doing something right as a parent.”
“This is a family ran business. Once you are a part of the academy you are a part of the family. The best thing we have done for our kiddos. Self respect, discipline, determination, focus, GREAT PROGRAM!!”
“The instructors are patient, encourage the children to achieve top academics, and consistently reinforce positive character traits. My children love the homeschooling program.”
“We just joined a few weeks ago. I am so impressed with everyone here. These master trainers LOVE these kids! Honestly, I don’t know how they keep these kids focused, but they do. Absolute positive energy from the minute you hit the door!”
“My kids enjoy the personal interactions with Ma’am and the GMA family encourages the kids to follow their passions. We love GMA and have recommended this awesome place to our friends.”
“It has made our boys so respectful and considerate. Wonderful teachers and great atmosphere.”
“GMA has been a wonderful place for our grandson. It is his happy place! The friends I have made mean the world to me. The community here is like no other.”
“Anyone that is looking for something whether it be just exercising to get back in shape, self esteem issues or whatever your need may be — consider becoming a part of this family. I have never met such encouraging and inspirational people. I am so glad I have became a part of this family.”
“My son has enjoyed it so much here. They always have fun activities for the kids and everyone is so kind. My son loves going there and so does my brother. I would highly recommend it!”
“We love GMA! Best decision I’ve made for my son. He loves Taekwondo and Master Davis! You become part of the GMA family when you join.”
