Our best, every day.

Since 1968, MML&H has engineered and surveyed the public infrastructure Louisiana communities depend on — from a single municipal fix to projects spanning the state.

Who we are

A relationship-based engineering & surveying firm.

Employee-owned and rooted in Louisiana, MML&H takes the lead — or joins the team — on projects of every scale. Each pin on this map is a community we've worked alongside.

Two offices, one state

Close enough to meet face-to-face.

Our Alexandria headquarters and Ruston branch keep a team within reach of clients statewide — so we can sit down and work through your project's challenges in person.

What we do

Full-service civil engineering & land surveying.
