Founded in 1952, CSDA is most proud of its seven decades of quality design. Under the leadership of Bill Corlett and Peter Skaer, the firm rose to distinction for such unique projects as the 1960 Winter Olympic facilities at Squaw Valley, numerous technologically sophisticated projects for the Department of Defense and educational facilities for all levels of instruction around the world.

From the beginning, CSDA has specialized in the planning and design of educational facilities. Over the past seven decades, we have applied thoughtful, innovative, and sustainable solutions to plan and design educational facilities worldwide.

Additionally, for the past 30 years, CSDA has provided airport noise insulation program management and design services for residences, businesses, and places of worship immediately surrounding international and municipal airports throughout California and all over the United States.

We value the long-lasting relationships that we have cultivated with our clients, and we endeavor to exceed client expectations by providing products and services that not only fulfill their requirements but generate additional value.
