Rev. Kalen McAllister was ordained by Rev. Shoken Winecoff in 2007 at Ryumonji Monastery near Decorah, Iowa. She is a long-time practitioner of Zen, and was active in the operation of the Missouri Zen Center for many years. In March, 2009 she received an award from the Women's Buddhist Council in Chicago for her work with prisoners in several eastern Missouri prisons. In 2004 she co-founded Inside Dharma, an organization dedicated to assisting prisoners in practical matters, as well as supporting their practice of meditation and Buddhism.

Rev. Shoken Winecoff is founding teacher and abbot of Ryumonji Zen Monastery. He is a Dharma Heir of the late Dainin Katagiri Roshi, founder of the Minnesota Zen Meditation Center. Shoken also received formal training at Zuioji Zen Monastery and Shogoji Zen Monastery in Japan for three years from 1989 to 1992. Since that time he has worked to establish a Soto Zen monastery in the Midwest. He is a frequent visitor to Shinzo Zen Meditation Center, and sangha members from St. Louis attend retreats and teachings at his monastery in Iowa.
