Mackenzie’s vibrant and welcoming culture embodies the collaborative spirit we’ve nurtured together for nearly seventy years.



At Mackenzie, we embrace our responsibility to positively impact Corporate ESG (Environmental, Social, and Governance) initiatives, which we set in motion in 2024 as vital for our business.

We are committed to ethical practices, prioritizing transparency, accountability, pay equity, and anti-racist training.
As part of our Community Investment Plan, we introduced in 2023 The Mackenzie Community Fund. We invest in this fund to promote outside organizations committed to serving historically underserved or underrepresented students in architecture and engineering. The firm supports the next generation in our industry through internships, mentorship, and scholarships to K-12 and college students, and active recruitment for a more diverse workforce.


The firm is deeply committed to supporting an environment that sustains and nurtures long, creative careers.


Mackenzie began 1960 as a sole proprietorship, Tom Mackenzie, Consulting Engineer, and grew to Mackenzie Engineering, Incorporated in 1968. Architect Rick Saito, who joined the firm as a drafting intern in 1968, partnered with Tom to form Mackenzie/Saito & Associates in 1977. The companies merged in 1996 and became Group Mackenzie to reflect better a shift away from a single-leader structure to a team/partnership approach.
In 2004, the company opened offices in Seattle and Vancouver, Washington. In 2013, the firm underwent a carefully considered rebranding process and emerged proudly as Mackenzie. Continuing our growth Mackenzie expanded and opened Its newest location in Sacramento, California in 2025.
