Aikido is a non-violent Japanese martial art that translates as

"The way of harmonizing life force energy."

Crystal River Aikikai was established in 2024 to serve the community in and around Carbondale, Colorado. At that time, our Sensei, Ann O'Brien, had been teaching along the Crystal River for 2 years, along with 5 years at previous dojos.

We are affiliated with the United States Aikido Federation (USAF), under the direction of Reuven Lirov Sensei. The themes of purification, healing and energy flow are resonant with our mission.
