Marlene Imirzian unknowingly started down the path to designing the Bob and Renee Parsons Leadership Center for Girls and Women decades ago, when she was just a young Girl Scout. True to that organization’s motto, when Imirzian was being considered to design a new scout camp south of downtown Phoenix, she was prepared. “I wore my sash to my interview,” she says of the part of the uniform on which Girl Scouts display their badges and awards. She also brought her knowledge of sustainable building and, in 2010, her firm was hired to create a master plan for the 14.5-acre campus at the edge of South Mountain Park. The Girl Scouts had owned the property since the 1920s, using it as a camp, but, with outdated structures and paved areas dotting the land, it was time to look toward the future.
