Past Chair
Mark Oberholzer, AIA
Context is everything. In cities like Los Angeles, context includes not just existing buildings and neighborhoods, but an emerging sense of urban identity and possibility. Mark Oberholzer’s strength is engaging with the context of client goals, zoning complexity, urban design, stakeholder influences, economic imperatives and design integrity to tease out extraordinary architectural solutions.
Over the last five years, Mark has been at the forefront of KTGY’s expertise in innovative construction techniques – harnessing the design possibilities of modular construction, bearing steel stud systems, and heavy timber. Mark sees construction technology as another part of the design context, bringing a conviction that collaboration, imagination, hard work, and a sense of humor are the best tools to reach the goal of better design.
