About our School (DOJO)

Aikido, Iaido and Jodo are not only fun martial arts and great stress-relieving exercise, but embrace a practical philosophy useful in everyday life and in everyday situations. CEOs, business managers, employees, teacher, students and parent practice these arts, yes, to defend themselves, but also to help them be more productive, level-minded and to help improve their conflict resolution skills.

Castle Rock AIKIDO is an adult-exclusive martial art school. Working adults and parents need a place where they can get a great workout, shake off daily stress and not have to think about children or other family obligations for a few  hours each week. In fact, it is very common for couples/parents to train Aikido together or come on opposite nights.

We love kids. However, our adult Aikido program is exclusively for adults… no exceptions. You might even say that our program is a “playground for adults.” Children already have so many different activities to participate in. It’s time us adults have a place and an activity just for us.

To the best of our knowledge, we are the only martial arts school in the greater Denver area offering adult-exclusive classes. CLICK HERE to read why we offer this unique service.

Group Aikido Classes

Our core program is the Group Aikido Classes, which are held throughout the weekday evenings and on weekends.  Students of all levels (beginner, intermediate, and advanced) may attend any or all of these class offerings.  A typical class can be anywhere from 5 to 20 students.  Please contact us for further information.




Private Aikido Instruction

For those unable to attend the Aikido Group Classes during the weekday evenings and on weekends OR for those preferring private instruction, we offer both 1-on-1 (one student and one instructor) and 2-on-1 (two students and one instructor) private instruction throughout the week during non-group class hours. Please contact us to inquire further.



Family Aikido Instruction

Our group classes are adult-exclusive – that is, no one under 18 years of age is permitted in our Group Classes Aikido program.  However, under very specific circumstances, we will permit semi-private instruction to families wanting to learn Aikido together.  Please contact us to inquire about Family Aikido Instruction.




Aikido Distance Learning

Castle Rock AIKIDO has just launched its Online Distance Learning Program (a.k.a. the Virtual Dojo).  Students from anywhere in the world will be able to train with Castle Rock AIKIDO’s instructors via video and interactive communication.  You can even earn rank from us.  Contact us for details.



Aikido Seminars

We hold between 1-3 Aikido seminars throughout the year with some of the art’s most popular, most talented, and most sought-after Aikido instructors.  These Aikido seminars are open to the public, to all Aikido practitioners of any school, and of any Aikido affiliation or no Aikido affiliation. To be placed on the Aikido seminar mailing list, please complete the form at the top of this webpage.



Weapon Arts

We also offer two unique weapon arts: Iaido and Jodo.  These arts are also for adults only.

We Value Simplicity and Transparency.
