In the May 30 print issue, ENR Texas & Louisiana will include its annual Top Design Firms ranking by both total regional revenue and by sector, featuring design firms from across Arkansas, Louisiana, Mississippi, Oklahoma and Texas.

While our initial deadline has already passed, we've received numerous requests to extend the deadline for those design firms still hoping to participate. We've decided to make an extension to one final deadline: April 22.
