Kathy Nyhan's participation in many of our Green Gulch retreats was a unique treasure.   Her radiant smile lit up the yurt as she careened into our midst. The delight of her bright face, the sound of her chair's wheels whisking over the tarp to her table meant our community was complete.  In the deep silence of our sessions her fierce concentration while painting was an inspiration.  Her laughter, her rich voice when she read a poetry selection, and her affection for Green Gulch added a memorable grace to our work and our companionship.
