About Us

Allison Engineering Group, Inc was started in 2004 by Lee K. Allison PE, FNSPE when he observed the growing need for a local presence to provide quality professional land development and municipal civil design services in Denton and surrounding areas. With years of hands-on project experience to draw upon, our diverse staff delivers innovative, appropriate, and valued solutions for each project.

As provider of professional land development services, Lee insists that Allison Engineering be intimately familiar with local ordinances, regulations and processes and to be a consultant on whom every developer can confidently rely. Lee continually reminds AEG’s employees that as consultants, it is our job to know the regulations better than the regulators.

Our entire team is dedicated to your success. We cannot accomplish that unless we know your expectations, you know our intentions and we work together to merge the two into a successful project.


Our Professional Engineers are active members of the Texas Society of Professional Engineers.

Project Philosophy

We focus on your project success…
We want you fully operational as efficiently as possible.
