Georgia's pictureGeorgia Erdenberger, EDAC, Principal

A 1973 graduate of the University of Florida’s College of Architecture & Fine Arts, Georgia began her design career as a space planner and interior designer for the Internal Revenue Service in Jacksonville, Florida, where she was responsible for office planning and facilities assessment for the 21 posts-of-duty throughout the State.  After relocating to Portland, Georgia was offered a design position at Karol Niemi Associates.  Over her 8 years at the firm, she was the project designer and manager on all scales of commercial and residential projects which included space planning and furniture coordination for Pacific Bell Northwest, design development, construction documents and construction administration for multiple projects at Providence Medical Center, as well as the design team member for interiors for the design and construction of the African Exhibit and cafe at the Washington Park Zoo.

In 1986, Georgia and former college classmate, Linda Czopek formed the interior planning and design firm of Czopek & Erdenberger.  As a founding Principal, Georgia was involved in developing a strong and varied client base, along with a reputation for high quality, creative and collaborative design solutions.  Over the 26 years of the firm, many long-term relations continue, including the City of Portland, Bonneville Power Administration, University of Oregon, Oregon State University, Oregon Health & Science University, Adventist Medical Center as well as a number of PeaceHealth facilities.  Georgia is an NCIDQ-certified and EDAC accredited professional.

As a dedicated painter outside of the office, Georgia’s artwork has been featured on the 2011 seasonal marketing materials for the Third Angle New Music Ensemble and recently is seen on the cover of the new “River Project” CD by Eve Beglarian.  Georgia also nurtures her love for the arts through her position on the board of the PNCA/Museum of Contemporary Crafts.
