Get to Know Us

Successful projects are only possible with the right people. At Triad, we’ve built a team comprised of both seasoned professionals and fresh talent. That balance of experience and new perspectives offers value on every project.


Brandon Marcott, P.E.
Principal Engineer/Owner

Having an opportunity to pursue professional hockey, Brandon instead decided to become a civil engineer – an idea originally sparked during career day in 7th grade. He’s been David’s right-hand man since joining Triad 10 years ago, just before graduating from the University of Alaska Anchorage in 2006. Born and raised in Alaska, Brandon previously interned as an inspector with the Alaska Department of Transportation and Public Facilities, and worked in materials testing for Allan Murfitt Company. He is a licensed P.E. in both Alaska and North Dakota. Known for his ability to think outside the box, Brandon enjoys the uniqueness of each project, which requires new solutions to be thought out and implemented.

Grant Mathews, E.I.T.
Project Engineer

When he was younger, Grant wanted to be a Lego Master Builder. While he’s no longer playing with Legos, Grant is still building – but now he’s helping to build communities, driven by the belief that safe and sensible civil design is the foundation of lasting community development. A third-generation Alaskan, Grant finds joy in living and working in such a beautiful place. He joined the Triad team two years ago, following his graduation from Calvin College in Michigan, and says he most appreciates the teamwork, the collaborative atmosphere and the unique challenges presented by each project.

Marty Westbrook
Civil Designer & Field Inspector

Marty came to Alaska in 1980, planning to stay for one year. She’s called Alaska home since then. With 38 years in the industry, Marty has been a member of the Triad team for 16 of those. Driven by her trademark “get-er-done” attitude, Marty assists in the design and review of plan sets, and conducts field inspections during project construction. Known as the “permit queen,” Marty is also in charge of obtaining and submitting permits. She holds an associate’s degree in engineering and drafting technologies, and previously worked as a project engineer with the Alaska Department of Transportation. In addition to the support of her co-workers, Marty most enjoys seeing a project progress from design through construction.
