We signed our daughter up to D1 & Only Martial Arts after she was hit by another student at school. We wanted her to know how to be able to protect herself. We liked it so much that we enrolled all our kids. It has been a great experience for them all. They love coming to class and learning new skills and are also held accountable for their own behavior.

Great, friendly, and flexible staff. Master Tim and his family are awesome people and everyone I've met there have been nothing but kind. I would recommend this martial arts studio to anyone, especially beginners. I wish I had joined sooner.

Amazing atmosphere, positive environment. I recommend anyone looking to join martial arts go see Sifu Tim Calvin. It’s much more then karate it’s a life changing experience.

My son as only been here 2 days and he loves it. The instructors are really nice and patient and they make you feel like family. Also they explain everything detail to detail about your membership. I’m really happy with the decision I made in taking my son here.

Very friendly and family oriented place, they put on a lot of free events through the year bbq's, movies night, nerf wars, pizza parties, etc... so you get to know Master Tim, the staff, and other parent's/kids. The classes are amazing, it built my sons confidence, made him more respectful, physically fit, and work hard for what he earns. They work with each parent to figure out how they can help your kid, by you deciding there indivdual goals for them to earn there tips to go up in belts. My son tries his hardest and love earning each tip because he knows it gets him closer to his next belt. Theres actually closer martial art dojo's to where I live but when I visited them they were not what I was looking for my son to learn. At d1 and only they run realistic scenarios from stranger danger to fighting off multiple attackers, what to look for in your surroundings, staying calm and how to react. This is a great place to have your kids attend or even for your self, can't recommend this place enough, if Im not mistaken they have free trial memberships so you can see what a difference it makes.

D1 is a 1 of a kind Martial Arts Studio, it doesn't only offer classes on how to take down and defuse an assailant or a threat, but also discipline and self esteem for all ages, it also offers a healing outreach for the family through having game nights, parties for the young adults as well as the older adults which builds the family unit.

I and my family have been with this school for over 10 years. The master instructor, Sifu Tim Calvin, is a great teacher for both adults and kids. He is patient, but firm. He focuses on your strong points and understands if you have physical limitations (I have a bad knee, for example, so he will alter whatever needs to be altered during the workout so I don't get injured, but still get a good workout). His curriculum is very practical and real-world, using techniques for stand-up fighting and ground fighting alike. His son and daughter have also grown up in the school and are following in their father's footsteps.

This school is definitely worth your time.

Amazing place that is honestly such a family feel. They not only teach self defense but they focus on respect and how to live it everyday. They are so encouraging to the children and help build them. It reminds me of the old saying “it takes a village...”. I’m ecstatic that D1 is part of our village!

I couldn’t be more happy with my daughter and stepsons karate classes. It’s teaching them dedication, goals, listening, and they absolutely love it. Not to mention they do free events for the parents! Great place. Great staff!
