How It Started

How It Started x

When Scott Hattenburg and Lorie Dilley first opened HD’s doors in 2001, they were a team of two. Quickly, they hired much-needed help and began writing A LOT of proposals. The following year, Dennis Linnell joined, forming Hattenburg, Dilley & Linnell. The Alaska engineering company recruited more talented staff and eventually landed the Parks Highway MP72-83 Rehabilitation project — a major win for a newcomer on the scene.

Early Days

Early Days x

In late 2000, Dave Lundin was a new PE who had only recently moved to Alaska. Scott approached Dave about the new company, and Dave followed him to HD. Dave — the company’s first employee — was given the opportunity to buy in as an owner. He has remained an owner of the firm ever since.

When Dennis joined, he brought Jeff Fuglestad, Carita Backman, and Nancy Yarmack to create a highly competitive Transportation Group.

During those first few years, the company’s five-year goal was to grow to about 20 or 25 employees and earn $5 million in revenue. They exceeded that goal in three years.
