Prior to the conception of testani design troupe in 1997, Judith spent several years absorbing, listening and engaging in a variety of hospitality design projects with highly regarded mentors and clients alike. Her background also includes a year at the internationally recognized Taliesin Associate Architects where she had the opportunity to work alongside some of the most iconic associates of Mr. Frank Lloyd Wright. For the past three decades, her primary focus has been in the hospitality/spa design arena, an area of design she finds both challenging and fulfilling. Her intuitive and holistic approach to this area of design has generated comforting and healing to dynamic and energetic environments throughout the country.
