Tell the boomer folks there's a different kind of belt that's way more effective at teaching discipline and it's here with Master Sunmi and Master Kim. I drive my son here from the opposite end of the valley twice a week because they are worth every mile and minute. I am in awe every time I watch them teach these kids- whether it be a class of 2 or 20- with ease and unwavering patience. They are not here to take your money to turn your kid into Hwoarang. They are here to improve the whole child (and the whole community) by teaching and modeling respect, self vs group awareness, initiative to support others, and inner strength. They have met my kid in all his moods and learning challenges without judgement. And I've noticed it's not just with my kid. They treat every single kid there in the same way- not robotically, but with an abundance of compassion and an understanding of how much they can push a personality to strengthen without discouraging. I'm not being dramatic when I say- this place, these masters, they're the secret to humanity. read more

My dad is a well-known Tae Kwon Do grand master so I have pretty high standards when it comes to Tae Kwon Do. This gym is exceptional. The masters are VERY GOOD. They teach the kids well and they also REALLY REALLY CARE about the kids. I also love how they instill the values of discipline and respect in the kids. My daughter has been attending for about 4 years and she loves it there. read more

My daughter has been attending US Taekwondo Porter Ranch, and we couldn't be happier with the experience! Master Sunmi and Master Kim are absolutely wonderful - they strike the perfect balance of discipline, encouragement, and fun. From the very first class, they made my daughter feel welcome and confident. We've seen such growth not only in her Tae Kwon Do skills but also in her focus, respect, and self-confidence. The studio has a very positive and family-friendly atmosphere, and you can tell the masters truly care about each student's progress, both on and off the mat. We love how they teach important life values like perseverance and respect while still keeping the kids engaged and excited to come back each week. If you're looking for a place where your child can learn martial arts in a supportive environment with amazing teachers, I highly recommend US Tae Kwon Do Porter Ranch! read more

Hands down the best Taekwondo place in porter ranch and the two Masters, Master Kim and Master Sunmi, are just unbelievable. Not only are they true masters at their craft, but they are so incredibly good with children. They somehow manage being so fun, loving, encouraging, personal, and command respect (and teach it) all at the same time! I wish my kids would listen to me the way they do with them (ha!) but I'm so happy they have such amazing role models in their lives. I'm so thankful both my kids are enrolled and plan on staying there until they both get black belts! as a mother, I highly recommend US Taekwondo. read more

Master Sunmi and her team are truly amazing, they are great with the kids and teach them respect and discipline.

He takes his classes very seriously and couldn't be more happy. They also do a reward program which keeps the kids motivated to keep going to class and earn trophies. I highly recommend them. read more

Both Masters Sunmi and Kim are exceptional teachers. They balance strong expectations of focus and respect while also making it fun for the kids. They are especially patient with my very squirrely five year old. They know how to keep him engaged and when to challenge him to focus. He's grown a lot in the program. They are also very communicative about updates, schedule changes, and host several additional events. We love being a part of the program. read more

My son has been coming here for several months now and he absolutely loves it! Coming to Taekwondo has done so much for his self confidence and for his discipline. We go to class twice a week and he looks forward to it every week. Master Sunmi and the gentlemen that work here are very professional and very kind. They run a very tight class with a combination of individual and group work. The kids are rewarded at the end of class with 1/2 stickers that they can then redeem for a medal/trophy (starting at 50 stickers). Since we put him in class we have seen an improvement in his concentration, discipline and respect. US Taekwando is a great place and I would highly reccomend it. read more

Such a great TKD school. Master Sunmi is an amazing teacher and really cares about her students.

I have two boys enrolled. One junior black belt and one blue belt. It's been almost 2 years and this has been a great source of stability and discipline for them. I like that this is consistent, year round activity that can easily fit in our weekly routine. They offer a class schedule that has enough flexibility built in that we can pick up other sports/activities seasonally. This is a good fit for the boys because the progression system keeps them motivated to keep climbing up the ladder. They also offer opportunities like movie nights or Taekwondo tournaments that break up the usual class routine. Not to mention the fun games they play at the end of most classes like dodgeball. We will be sticking with this studio until black belt and beyond. Highly recommend! read more

My son Ellis loves attending his classes here at USTaekwondo, Porter Ranch! Great discipline, leadership, character, skills, patience and determination is what he's learned. Master Sunmi & Master Kim are awesome with the kids! I highly recommend this place! read more

My 6 year old loves the class here. Good teaching around discipline and concentration too.

My son has been going here for over a year and a half and it is one of the best things we've done for him. He's not a competitive kid and we were looking for an activity that would hold his interest and that he could really stick with and grow both physically and mentally. A year and a half in, he's happy and has grown tremendously in focus and confidence. Master SunMi and Instructor Kim are both wonderful. They both have a real knack for working with kids. They are kind and supportive but firm and structured. This isn't just a get them moving activity. The kids really are learning the practice and it benefits their mind and body. The mental is stressed just as much as the physical. My kid is nowhere near the best in the class but Master SunMi and Instructor Kim have never made him feel anything but capable and supported. I can't say enough good things about them. I highly recommend! read more

A solid investment in your child's future. The skills my son has learned here will stay with him for the rest of his life. Masters Sunmi and Kim know instinctively when each child needs a bit of tenderness and when he (or she) needs a push in the right direction. They balance a lot of gentle encouragement with a little bit of tough love. The change in my child's focus, follow through, responsibility, self control and respect for elders has vastly improved since he has been coming here. This is not a "Black belt factory" like many studios that rush their students through for money. The children work hard and achievements are earned, not given. I look forward to many more years of watching my son grow and blossom under their tutelage. P read more

I came here as a child and was trained for 6 years by Master Ko and Master Luc. I loved the experience so much that I now have both of my boys here learning from Master Sunmi. It is so important to me that my boys learn not only how to channel their energy towards active learning and teamwork each day, but towards building their character as well. They're not only learning self defense techniques but also are learning the fundamentals of respect, discipline and focus. This benefited me so greatly and that's exactly what I want for them too. They look forward to coming here daily to earn their badges and see their friends and master Sunmi and I love how they incorporate games for the young ones to let them play together. read more
