Ro~Sa is a collaboration between artists Robin Assner (St. Louis, MO) and Sarah Nitschke (Milwaukee, WI). Meeting at an artist residency in 2004 Assner and Nitschke recognized in each others work a deep, shared interest in exploring ideas about the nature of human experience. Nitschke has a BFA from Washington University in St. Louis, MO and an MFA from University of Colorado at Boulder. She also trained at Central St. Martins in London, England and the Art Institute of Chicago. She has exhibited nationally and internationally and been awarded many grants for her work. Assner received her BFA from the University of Connecticut and her MFA from the Ohio State University. She has had many group and solo exhibitions and received many awards for her work. Their first collaboration—begun in 2004—is Acts of Hope and Futility a long-term, multi-part, multi-disciplinary project that includes performance, photography, video and installation. The collaboration enables a unique formation of ideas to coalesce into art that addresses issues of the power of ideas, objects and rituals, the body, women's role in society, and the human quest for happiness.
