Due to the retirement of Senpai Okuma and the Semi-Retirement of Sensei Parker, there are no longer any group classes at Mumonkan-Do Aikido. After 13 years of dedicated teaching, Senpai Okuma retired in June, 2018 in order to care for his aging mother. After 33 years of dedicated teaching, Sensei Parker semi-retired at the same time, in order to dedicate more of her time to her private healing practice. Sensei Parker currently teaches only private and semi-private lessons for those students who have been dedicated students of hers for 10-25 years. Because of her semi-retired status, she is not accepting new students.
