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!
Highly recommend D1& Only! they are family oriented and the best people. if you want to be a part of something great this place is for you my kids have grown with them and we should have more caring people like them in our community, they are not all about money -- they invest in your children and their futures!
They are great mentors!
