Our New Mural

Rising Up

We take pride in our mural painted by Portland Artist Christa Grimm! Two Rivers Aikikai chose Christa to paint the new mural called Rising Up after a considerable search for an artist who could create a mural which embodied our goals of practicing non-violence in body, mind and spirit. The mural represents perseverance and connection to meet life's challenges with the support of our environment and community. The underlying philosophy of Aikido practiced at Two Rivers Aikikai is one of harmony with one's surroundings. The mural imagery of a migrating salmon, water currents, and cyclical forces resonates with the notions of blending, pliancy, giving and receiving, all of which are qualities practiced at Two Rivers Aikikai.

Portland artist Christa Grimm creates murals, paintings and large scale site-specific commissions for both public and private clients. Alive with color, movement and strong, confident brush strokes her images celebrate natural beauty and human vitality.

Instructors at Two Rivers Aikikai

At Festival Japan Iaido and Aikido demonstration Sept. 2008.

Our Chief Instructor is Spiros Koyanis Sensei, 6th Dan, Shidoin in Aikido and 4th Dan in Iaido. He is a direct student of the late Mitsunari Kanai Shihan and practiced under Kanai Sensei's guidance for twenty one years. Koyanis Sensei began his training at New England Aikikai in 1983 and has been teaching Aikido to adults and children since 1989. In 2001, he became Chief Instructor of Two Rivers Aikikai. He is a firm believer in the effectiveness of non violence and as such honors the memory of Kanai Sensei in his instruction by paying close attention to Kanai Sensei's dynamic theories of the unified body and the interaction between uke and nage based on budo. Koyanis Sensei believes that Aikido is a fluid martial art that continues to grow and change based on modifications by leading practitioners. He trains several times a year at USAF seminars under the direction of Yamada Sensei and the members of the USAF Technical Committee. Koyanis Sensei practices and teaches Iaido as taught by the late Mitsunari Kanai Sensei, Grand Master of Iaido. Two Rivers Aikikai is a member dojo of Kiyoikaze Iaido Federation under the direction of Claude Berthiaume Shihan.

Kanai Sensei and Lynn Marshall at Summer Camp 2002
Lynn Marshall, 5th Dan, Shidoin is also a direct student of Mitsunari Kanai Shihan. Lynn practiced karate for a year before starting Aikido at New England Aikikai in 1985. Lynn's extension and precision demonstrate that one does not have to be big to be effective. Lynn's ability to break down a technique and focus on details gives students a lot to think about and work with in the beginner and basics program at Two Rivers. Lynn has been practicing at Two Rivers Aikikai since July 1998. She teaches a wide variety of techniques and often includes bokken and jo kata and suburi in her classes. With a strong emphasis on basics, Lynn demonstrates advanced techniques with clarity and precision for students in mixed level classes. She is a reliable reference for students preparoing for kyu and dan tests. In addition to Aikido, Lynn practices yoga several times a week and brings a wealth of knowledge to our students about proper stretching techniques to gain flexibility and strength. Lynn continues to hone her Aikido techniqe at USAF seminars throughout the year. In 2014, Claude Berthiaume, 7th dan shihan and a member of the USAF Technical Committee promoted Lynn to 5th Dan in Aikido.

Our Facilities

It's a big mat.

Two Rivers Aikikai occupies a former futon factory on Southeast Belmont Street. It took several months of hard work to clean and renovate the space. Our Tokonoma and 1500 square foot mat were built by our students. We have separate dressing rooms with showers for men and women. Part of our training includes sweeping the mat after class and keeping the dojo clean and neat. We are very proud of our dojo and invite you to stop by to observe class.
