It is with heavy hearts that we share the passing of Greenbusch co-founder, Julie Wiebusch.

Julie, together with John Greenlaw, formed The Greenbusch Group in 1989, growing it from a two-person shop to a firm providing engineering and design services across the Pacific Northwest and beyond. An accomplished Acoustical Designer, Julie's career was defined by her solid work ethic, enthusiasm for acoustics, gracious compassion, and unwavering dedication to quality. For the staff at Greenbusch, Julie was an outstanding boss, an encouraging mentor, and a dear friend who will be sincerely missed.
