Barbara has been with MASON since 1989.

Barbara values opportunities to protect and renew our community’s architectural treasures. She particularly enjoys the technical challenge of restoring Hawaiʻi’s storied places and has designed the restoration of significant historic buildings and residences, including award winning projects at Shangri La, Kaumakapili Church, and the Cathedral Basilica of Our Lady of Peace. She has prepared design guidelines and preservation plans for historic places as diverse as Kokee and Waimea Canyon State Parks, Punahou Campus, and the Hana Highway Historic Bridge District.

Her first preservation project, as a university student, involved the restoration of the Taman Ujung Water Palace in Bali. This sparked a lifelong enthusiasm for travel that she enjoys sharing with her archaeologist husband and two college-age children.
