Leadership & Team
The people who carry the work.
Collier Engineering is led by founder and CEO Douglas Collier and a small bench of directors who own engineering, operations, safety, and client relationships. Open seats, when they exist, are clearly labeled.

From the field to the front of the firm
Douglas Collier did not start in a corner office. He started in the field — on fuel sites and industrial pours where the difference between a good day and a dangerous one came down to preparation, discipline, and whether the people in charge actually understood the work.
Those years left him with two convictions that still define Collier Engineering. The first is that engineering judgment cannot be delegated to a spreadsheet — it has to live with people who have walked the site, read the ground, and stood next to the equipment. The second is that safety and quality are not competing priorities with schedule; they are how you protect the schedule. A crew that works safely and builds it right the first time is the fastest crew on any honest program.
Why he founded Collier Engineering
Douglas built this company to prove that a U.S. construction and engineering firm can be demanding and humane at the same time — rigorous about documentation, uncompromising about safety, and genuinely good to work with. He leads the firm the way he ran his first crews: by being early, being prepared, and refusing to confuse motion with progress.
He stays close to the work that matters most — the high-consequence builds in oil and fuel infrastructure, industrial facilities, and energy projects where there is no margin for the careless. Under his leadership, Collier Engineering measures itself not by how loudly it markets, but by whether the last client would hire the firm again. That, to Douglas, is the only credential that counts.
The team
The directors behind every project.
Each director owns a discipline end to end — and is in the room when the schedule, the safety plan, and the engineering decisions get made.

How we work together
Operating habits that hold whether the team is four or forty.
Plain talk
We tell clients, owners, and each other the truth as we see it — early — even when it is inconvenient.
Stop-work means stop
Anyone on the team can pause work for a safety concern. No questions, no penalties, no apologies needed.
Write it down
Decisions, RFIs, hold points, and changes get recorded. The record is part of the work — not an afterthought.
Hire for the standard
We grow only as fast as we can find people who carry the firm's standard — in the field and in the office.
