Building the Foundation

MacKay Sposito was born in 1974 when Don MacKay and Richard Sposito purchased the Vancouver, WA branch of MacKay & Somps. The focus was on land development work, including the early stages of the Cascade Park master planned development that eventually evolved to reshape the Vancouver area and surrounding communities. Our primary service areas began as civil engineering, land surveying, and planning.

Progress & Persistence

The recession of the early 1980s took its toll, but MacKay Sposito weathered the storm. We designed increasing amounts of public infrastructure as our presence in the Public Works market continued to grow. Richard Sposito became our company’s second President upon Don MacKay’s retirement.

Maintaining Momentum

MacKay Sposito experienced growth in both Land Development and Public Works sectors. Major projects that began during the 90s include the Fisher’s Landing master planned development in east Vancouver and Columbia Tech Center, one of Vancouver’s largest employment centers.

Results & Resilience

MacKay Sposito rode the wave of the new century’s construction boom, opening our first branch office, located in Kennewick, Washington. Al Schauer became MacKay Sposito’s third President after the retirement of Richard Sposito. Our construction management service area took root, and in 2006 we added landscape architecture to our services. The Great Recession hit, but we survived and thrived by being creative, adaptable, and finding new ways to utilize our skills within the Energy market.

Evolution in Action

Tim Schauer became MacKay Sposito’s fourth President when Al Schauer retired. We opened a branch office in Federal Way, Washington and began working on Tehaleh, a 4,300-acre community in Pierce County. MacKay Sposito rebranded in order to better showcase and reflect the company we have become. In 2019, Derrick Smith became our fifth President, and we added environmental services to our roster.
