My son has been attending Gretna ATA for a year and has learned so much. Ryan is a great teacher. He not only teaches the kids martial arts but also important values like discipline, respect, communication . And also self defense on a way that kids can understand and use if needed.My son has improved physically and he has gain so much confidence. All while having fun. I plan on having him attending this school for years to come. It’s a great investment on your child physical and mental health.He offer free trials and honestly, after you watch his classes, you will understand the quality of his service. This is a wonderful martial arts school.

The best! Outstanding instructors. Supportive environment.

I love this place. Ive been coming here for about two years, and I already want to be an instructor (and that is due in no small part to my own). This school has been a huge benefit for me. Ive gotten good exercise, perfected fun techniques, learned vauable life lessons, and made great friends. There is no other school I would rather be going to!

I have to admit that this is the best place to learn and my favorite place so far. Its been helping me alot from getting a job to getting to make new friends. Almost all the kids will agree with me that this is the a respectful, helpful, friendly, and the instructors are trying to help the students even the adults and even me a 2nd degree black belt. Mrs. Kendal is a great weapons teacher and will help anyone same with Mr. Miller and I dont regret moving to this Martial Arts.

Highly recommend this studio!! Ryan is a fantastic teacher - Incredibly knowledgeable, friendly, accessible, and thoughtful to the needs of his students. His classes flow and connect in an intuitive way from the warm ups to the drills to the techniques. And it’s a killer workout to boot! Super thankful I found this place when I moved here and I look forward to every class. If you want to learn real life, practical self-defense from one of the best instructors around, look no further! I’ve taken Krav Maga for 8 years and this is the best studio I’ve been in.

Gretna ATA is a great school my son has been in the extreme tigers program for the last year and will be moving up to the traditional program in the next month or so. Master Miller has a tremendous amount of patience with the kids, but does a great job of reinforcing discipline in the class.Since joining my son has grown tremendously in his ability to focus, set & accomplish goals, and has had an overall improvement in his attitude. He absolutely loves the extreme tigers with the focus on weapon and sparring skills.Would highly recommend Gretna ATA and Master Miller to anyone looking to get themselves or children into the sport.

My 10 year-old son has been attending Mr Miller’s ATAs school for 7 years. In those years he has learned life skills while having fun. In his early years he learned respect for others, and reinforced skills learned in school like how to line up and proper listening skills. Mr Miller’s school provides a safe environment while learning self-defense. ATA has given my child great self-confidence and personal development.

I was able to attend a Krav Maga class and it was fantastic. They accepted me where I was in my training and helped me build on that in a fun, but challenging way. I got to learn great skills as my two daughters played and watched Mommy do arm bars, jab/hook combo punches, and basically Get After It. Super energizing and was able to learn from other members who were so accepting and excited to teach. Definitely recommend!

Fantastic school for martial arts! Ryan Miller has such a way with the kids. So respectful, kind hearted, and dedicated in what he teaches. You can really tell he loves what he does. He takes pride in instructing. Its nice to go to a place that shows you how to have fun and really enjoy yourself, while also focusing on teaching respect, integrity, self control, as wellas outstanding discipline. My boys have struggled over the years with ADHD as well as being bullied at school. They have now been going to Mr Miller’s for 6-years. They go to class 4 times a week and truly enjoy it! I have seen their self confidence shine! And they are able to really focus and learn new things. When they travel for their tournaments, the excitement is grand. They wear their medals in honor of the ATA!!!

My 8 year old started 2 months back, already, change in him is impressive. Martial arts teaching him to be discipline, punctual and learning all the time. I am extremely impressed with teaching. Happy to found this place. Highly recommended !!

I have had my 6 year old son in ATA Tigers for 8 months and he simply loves it. Even with the young age of the tigers, Mr. Miller does a great job keeping it structured and fun at the same time. Additional to learning the forms, Mr. Miller does a great job explaining why and what to do and he does it in a way to keep the students interested and excited. My son as learned a lot and has become a very dedicated student here. I enjoy watching him learn and improve. I can see in his face how much he loves it.

We have been to several martial arts schools in the Omaha area and Gretna ATA is by far the best! Our son has become more confident and is always a leader at school and in other activities he participates in. Master Miller is exceptional with kids and the classes are always upbeat and positive. Aside from teaching martial arts Master Miller also includes valuable lessons on how to handle bullying, having a positive attitude and making good choices.

I put my sons in martial arts two years ago to learn self defense, self control, and confidence. The experience we have gotten has given us so much more. It wasnt long before I enrolled myself in Taekwondo and Krav Maga classes as well. Mr. Miller focuses not only on the fundamentals of ATA, but he takes the time to explain and practice the practical application of the skills, while stressing the importance of how and when to utilize the techniques if necessary. Mr. Miller himself competes at the highest level of competition that ATA has to offer. He is one of the finest competitors in the world, and we are lucky to have him as our instructor.If you are looking for an opportunity to give your child the skills necessary to be fit, learn self defense, and provide him/her with the self-control and confidence he needs to be successful in life, this is your place. Students dont sit the bench here. They get the skills necessary to learn and grow at their own pace. Im proud to be a part of Gretna ATA!

We couldnt be happier! Mr. Miller combines the perfect blend of positive reinforcement and instruction. He keeps his students active and creates such a positive atmosphere! As parents, we love that he also talks about discipline, respect, and responsibility at home and school, and will talk with the kids individually to reinforce expected behaviors. Both of my boys, ages 8 and 10 look forward to going to class!

Great class. My daughter enjoys coming to class everytime. Mr. Miller (instructor) has a great approach with the kids and keeps everyone engaged and accountable. Helps build discipline.

My daughter had a really great time learning self defense skills today. We are excited for her to feel brave and strong. I am also excited to try their adult classes for fitness, strength and self defense!

Highly recommend Mr. Millers classes. My son is in the Tigers class (age 5) and its something that he loves and has taught him not only the basics of martial arts, but so much more in discipline, listening, self improvement, etc. Mr. Miller is so patient with the kids and I know my son looks up to him as a leader in his life.

I have been taking kickboxing classes at Gretna ATA for 2.5 years or so and I love it. They are challenging work outs that are a ton of fun. The works outs are always changing so you never get bored and the people at the school are fantastic to be around. I would highly recommend this place to anyone who wants a good, fun work out

Mr. Miller is an excellent instructor. He keeps students engaged while being active. I love ATA because of all the options. There is Taekwondo, Kraft Maga, leadership and even training on how to be an instructor or a judge at tournaments. I highly recommend this class and location because Mr. Miller is the best.

My child has gained self-confidence and has learned a very important life skill. He loves going to class and has made many new friends. Mr Miller is an outstanding instructor and I would recommend his classes to anyone!

We highly recommend Gretna ATA! Not only does this sport/martial art promote physical engagement, competition, and health, like most sports do, but it also focuses on important aspects of character development.My son has learned about respect, discipline, and effective communication, etc. These ideas, among others, are always intertwined throughout each class and are truly helping my son mature into a right-minded person.He is also learning how to apply the skills he learns in class to real-life situations such as abduction, bullying, etc. Unfortunately, these kinds of situations are prevalent and the knowledge of these skills is priceless.I really cant think of an activity for our son that is more well-rounded and we also believe that Mr. Miller has an undeniable passion for his school and his students! These two reasons alone are why we chose Gretna ATA!

This has been a top notch school for my son the last 3 years. Mr Miller is very professional and clearly cares about each of the students. Highly recommended!

Our first experience with this place was when we enrolled our son in taekwondo classes. It was amazing to see so much growth in him...not only physically but also in his self discipline and his confidence. Now, not only is our son taking classes but my husband and I joined as well! We love this place and Mr Miller and would recommend it to anyone!

Mr. Miller is a wonderful teacher. How he builds up kids and adults confidence and prepares them for life is amazing. Mr Miller is building future leaders today.Mike

We have been with Ryan at ATA now for a few years. We love his attentiveness to the students and his passion for taekwondo. He is a great instructor and role model for my daughter who has grown so much since joining not only in physical abilities but with attitude and confidence.

Gretna ATA is amazing! My 2 boys have been going for 2 years and have learned so much more than martial arts. The lessons of discipline, integrity, respect, responsibility, and commitment show at home too! Mr. Miller is amazing, and great with kids. I would definitely recommend this this place to families looking to start taekwando.

Mr. Miller does an excellent job teaching Taekwondo, Krav Maga, and Hyper Fight classes. My son and I do all three types of classes and are learning a lot about self defense, as well as getting a good workout! My wife joins us for the Taekwondo class as well, which makes for a fun family activity. Highly recommended for kids and adults alike.

My son is 5 and has been going to practice for almost 2 months now and he has learned so much in that short amount of time from Ryan! He has been listening more, behaving more and its really impressive how he looks up to his coach for guidance! They teach the kids discipline, respect, listening skills, etc. We will be around for many years thanks to Ryan!

I enjoy watching my daughter improve and get better every week. The instructor is great with the kids and really focuses on respect, which is great for the kids.

My son enjoyed this mornings self defense class. The instructors were friendly, engaging and patient with kids of all ages.

Mr Miller is a great teacher. Students learn excellent life skills. Highly recommend

We have had such a positive experience. Our son has built self confidence, learned about self discipline and practiced responsibility.

Ryan Miller does a great job as an instructor for Krav Maga, Taekwondo, and Hyper Fight in a manner that makes everything approachable but challenging if youre willing to push yourself.

Ryan is exceptionally good with the kids, theyJust luv him!!

Mr. Miller is very good with the kids and very patient.

My son enjoys class and Mr. Ryan!!
