My son started Karate with Master T about 18 months ago when he was 5 years old and he has made huge changes over that time. Karate has been excellent for his focus. He listens, looks, learns, and has developed a great sense of leadership. His leadership abilities have transferred into his Kindergarten class at school and his Sabbath School class. He loves to lead out at school and lead out at Sabbath School and all of the kids listen to him and respect him. It's amazing. He went from very shy to very confident! Karate has taught him discipline and Master T has been a huge blessing. The kids love him, but more importantly they respect him as well. Less

My son started karate lessons about 6 months ago and his experience here has been fantastic, so much so that I decided to start lessons myself. My goals have been to increase my physical fitness and improve my balance and coordination. As an adult I really appreciate Master Terrell and Sensei Garrett. Both of them are knowledgeable and passionate about martial arts and patient as well. My group class includes black belts and novices and they're able to tailor lessons to the range of skill levels in my class. My small group class is excellent and I've progressed so much from their 1:1 instruction. I really recommend USSD for adults and children, alike. Less

Both my boys have been going to karate here and they love it! As a matter of fact, WE all love it. My husband and I decided to try the Adult class, and it's one of the things we look forward to each week. It's a good workout and Master Terrell is such a great instructor (he has a great team of instructors too!). On somedays before class, I feel too tired to go after a long day of work, but I go a...

I am SO glad we took the leap into self-defense at USSD Oceanside! Less

We have only been at OSSD a short time but have been welcomed with the utmost care and respect. My son has special needs and has struggled with every group sport/activity he's tried. This was an entirely different experience - the happiest I have ever seen him! The instructors are kind but firm, hold the students to high standards but are thoughtful in their expectations.

We have only been at OSSD a short time but have been welcomed with the utmost care and respect. My son has special needs and has struggled with every group sport/activity he's tried. This was an entirely different experience - the happiest I have ever seen him! The instructors are kind but firm, hold the students to high standards but are thoughtful in their expectations. My son is learning martial arts, yes, but it also gaining valuable life skills like patience, confidence and most importantly, focus. I am truly impressed and feel lucky we found such a wonderful studio! Less

Our 14 year old daughter has been at USSD for 3 years now. She has grown tremendously in those years. Master T is an amazing instructor, especially with kids that might be a little “different” like our daughter.

A great place for newcomers to Shaolin Kenpo, kiddos and adults alike! I worked with Master Terrell and Sensai Garrett for 6 months. I placed 3rd in Forms at my first tournament and advanced to yellow belt shortly afterwards. My only regret is not extending my membership another month to get the most out of my final weeks in California.... More

USSD has been extremely beneficial for my children. My children have more confidence in themselves, higher self esteem, and learning to become great leaders. My son has learned to be more outspoken, and to speak with confidence. My daughter has taken the leadership skills she has learned and applies them to all aspects of her life. The instructors are amazing teachers and very patient with each individual child and their needs. Master Terrell is easy to work with and helpful with scheduling changes. My husband and I were students, and the adult lessons were great! We learned so much and the lessons we learned will stay with us forever. Master Terrell, again is excellent at catering to your individual health and physical needs. He worked with us to learn our forms, without harming or injuring ourselves. A great workout, while learning beneficial skills. I highly recommend USSD for children and adults. Less

My daughter has now been in 3 tournaments since joining. She has received 4 medals in all. It has changed her self esteem incredibly. Since joining she has made a 180*. She nom is getting a 3.3 gpa where before she struggled meeting grade level. She always thought she was less than because of struggles in school.After the first tournament she told me that she now knew she could accomplish things. Home life has been a struggle but, slowly getting better because at 11 they already act like teenagers. All the highschoolers that attend are so responsible and respectful. Most are high in belt rank and you can see how they have matured well with Master T”s influence. Master T is always there for parent support. Try this dojo with no worry of regrets. Less

My son has karate practice here, the instructors are GREAT!Highly recommend this place, great for k8ds to learn sel defense and discipline.

Master Deric has a lot of patience and he is super professional. 100% recommended!

I was very concerned about him starting so late and his challenges with ADHD however, I have read this was a great way to help him focus. The team at USSD addressed my concerns and accommodations were made to ensure he is challenged and accepted into the groups. We enjoying having an opportunity for personalized growth and joining in class lessons. I personally feel my son's self confidence has blossomed at USSD. My son looks forward to his classes and the "homework." We are so glad that we found such a welcoming place to grow. Less

We’ve been part of the USSD Oceanside Dojo Family for an entire year. There’s not enough accurate words of gratitude we have for Master Terrell and his dojo associates.

At the end of the day he genuinely cares so much for these kids, not about how well they can kick and punch, but about them growing into a decent human ... the kicking and punching is def a bonus. Starting this traditional style karate has shown our son his strengths, and also shed light on where he can grow and improve. The monthly tuition is not a “another bill” but an investment into your child(ren). Not 1 negative word to say!! Less

We appreciate the attention and mentor-ship you and your team have provided Riley and Jordan.

Well done, Deric! Less

He is a great teacher :)

He is very good with the kids. My son looks forward to it every time and can't wait for his next session and belt.

United Studios of Self Defense excels on all ways. I noticed from my earliest visits that Master Terrill is super adept at making his students comfortable and getting the greatest learning from them. He achieves this by meeting them at their level while maintaining a high degree of learning input. It is super fun to watch him with the little ones! He hires only the best Senseis as well; each of them remarkably talented in these learning/teaching arts. What a great experience this has been for our 13 year old who we placed here when football season ended to maintain his conditioning level. USSD went well beyond that, increasing his confidence and his responsiveness. Pure gratitude is what I feel about this decision. Less
