Mt. Kim, and more importantly Master Jeon and Mrs. Jeon have become a part of our family! As a…read moremilitary family, we have moved and lived all over the world. We have always wanted to put our kids in a martial arts program, but was never able to find the right fit for our family. When we decided to buy a house in Manassas in May of 2016, little did we know how much that move would change our lives. After we got settled, I began looking for a good martial arts school for my kids. I made personal visits to every martial arts school in the area... Mt. Kim and Master Jeon deliver a quality, caring, loving and challenging program. Every challenge and obstacle is overcome through encouragement and motivation. Master Jeon will push you to your limits and really show you exactly how much you can do. My kids started in Aug of 2016. They have grown soooo much! Each of them with their own special personality, Master Jeon and Mrs. Jeon get to know our kids and I really believe in my heart, they see our kids as an extension of their own family. In Dec of 2016, my kids finally talked me into taking class with them. It has been life changing for me. Master Jeon was patient with me in helping me to accomplish all that I have and helping me to get beyond the obstacles I faced. I was injured in the line of duty and never believed after 9 knee operations, ankle reconstructions, that I could ever "do this". I find myself every day doing things I never believed my body would again! All thanks to Mt. Kim Martial Arts! Their name says it all "Spirit". They have it in spades! We take many of the TaeKwonDo classes as well as their Comprehensive Martial Arts (which is their Hapkido and Judo classes). My kids also attend the before and after school program! They absolutely love it and never want to leave the school!! If you are looking for a challenging program where you have to earn your way to Black Belt and beyond... if you are looking for a school who will treat your kids with respect, love and encouragement... if you are looking for a way to get in shape and off the couch... most importantly, if you are looking to make a lasting positive change in your life the lives of your family, you can't do better than Mt. Kim. Hope to see you in class with my family!

Finding motivation in a child can be a challenge, but all the instructors really do a phenomenal job of balancing discipline and fun. The facilities are clean and easy to access. The prices are so incredibly reasonable and a very good option to provide an extra activity for kids. They seem to provide an engaging summer camp as well.

They made my six-year-old son and eight-year-old daughter feel welcomed and right at home from day one. My kids enjoy their Taekwondo classes every Tuesday and Thursday, and they love going to OSA after school. Since enrolling, I've seen such a positive change in their grades and reading skills -- the structure, homework help, and encouragement they get here really make a difference. This after-school program has been far better than the one they had at their school; the care, attention, and environment at OSA are on a completely different level. They also enjoy attending on teacher workdays, holiday closures, and special camp days -- it gives them something fun, active, and enriching to do instead of sitting on an iPad all day. I'm even planning to enroll them in the summer camp program because it sounds amazing and packed with activities that keep kids engaged and learning. I genuinely cannot say enough good things about this place. As long as we're in Manassas, my children will stay in this program. I highly recommend OSA to any parent looking for a safe, warm, structured, and enriching environment for their kids!

We were allowed to try both TKD and Judo before choosing so our boys could choose what they preferred. The boys ended up choosing Judo. They enjoy going and ask about when their next class is often. OSA staff is so patient with the boys. We had looked at martial arts before, but the boys immediately loved this program and us was an easy decision that this was the place for our family. There are so many activities that are offered that truly make this program worth it for us and the value of this program is great. It was important for our boys to be in a place that they felt like they belonged with appropriate structure for them.

Everyone's body and skills are so different, and these instructors fully embrace that. Their goal in Krav Maga is not to teach us pretty kicks and impressive moves - their goal is to make sure we get home to our loved ones safely. It is all about developing your mindset, muscle memory, and instincts so that, when it really counts, you avoid the deer-in-headlights effect. Even as a beginner, I feel like I walk around my community in Manassas with more confidence and awareness and have learned how to reduce my chances of being a victim in the first place. If for some reason you don't feel like you have the time to commit to classes, I HIGHLY recommend you check out their monthly seminars! Women's Self Defense, Edged Weapon Defense, Car Jacking Defense, and the list goes on!! After watching many of the kid's classes, I love what I see! They're teaching kids how to use their voice, how to stand up for themselves and when it is appropriate to take physical action.

We drop-in to CrossFit Manassas when we visit my parents in Haymarket, VA, and it is the best box I…read morehave ever visited. Not only do the staff and members welcome you with open arms (which is somewhat expected in CrossFit), but the coaches go the extra step to understand your strengths and weaknesses before the workout to ensure they can do everything in their ability to make you better and get as much value from the workout as possible. The staff's overall love and understanding of CrossFit shines through in the programming and the progressions/scales they provide to their members to ensure the highest quality CrossFit experience possible. In talking to the owner, the rigorous process and the required continuing education the coaching staff is required to maintain is unprecedented which also leads to a better CrossFit experience for both members and visitors. In our last visit, the box lived up to their unofficial name of "PR City" as I PR'ed my bench press - yes they programmed a regular bench press (not floor press) because they have enough racks and benches for the ENTIRE CLASS. Which leads me to another amazing aspect of the box - the equipment. Not only do they have a massive rig in the middle that can accommodate a ton of people, but they also have a dedicated area that has permanent gymnastic mats along the wall giving you a great place to work on handstand progressions or wall walks. Not to mention the massive amount of oly plates and rowers, but rarities at most boxes, but they have an OUTSIDE rig and dedicated stone pit. The use of technology to further the member experience is impressive as well. The staff encourages each member to report and track progress on beyondthewhiteboard, so that measurable results can be achieved. My wife, who is a Level 1 CrossFit Trainer at our home gym, said after our last visit, if we moved out of PA, we should consider the Manassas area just so she can coach and train at this facility. If you are visiting or considering trying CrossFit you cannot go wrong with starting at CrossFit Manassas.

We were immediately greeted by the two giant Mastiffs they have (which I can only assume also do CrossFit), and Jennifer got us checked in and introduced us to Coach Doug. They gave us a quick rundown of the workout for the day, and where all of the equipment was if we needed it. We met a few of the other people in the session, and it was great to see people of all skill levels knocking out the workout. It seemed like Doug and Jennifer gave us a little extra special attention because we were beginners, but they focused on safety and the right technique first, before they moved into building strength. I can safely say this is the first time I have done CrossFit and not injured myself. The facility had a lot of equipment in great condition, and they had a huge screen on the side of the wall that showed heart rate levels of some of the people in our session - it was very cool, and I enjoyed geeking out during the workout. The workout was good - not too intense, but my body is a little sore the next morning. Coach Doug even hung out with us for a few minutes after to encourage us to keep doing CrossFit if we feel it's right for us, and find something that works for us in our own towns. Overall, a great experience, very knowledgeable and fun group of people, and I would definitely recommend to anyone in the Manassas area - if nothing else, just drop in and try them out. We had a blast. Thanks, Doug and Jennifer! My shoulders thank you too.
