Sigma Engineers and Constructors is officially nominated as a 2026 LSU 100 Fastest Growing Business!

For the fourth consecutive year, we’re honored to be part of a group that celebrates some of Louisiana’s fastest-growing and most successful businesses.

This recognition is a reflection of the people behind Sigma — our team, thoughtful leadership, strong relationships, and the quality engineering solutions we deliver every day. We’re incredibly proud of how far we’ve come and even more excited about where we’re headed.

Four years on the LSU 100 list is a milestone worth celebrating — and we couldn’t have done it without the people who continue to make Sigma what it is!
