Innovative Engineering Is The GTA Experience


Geo-Technology Associates, Inc. (GTA) was established in 1985 and has evolved into a large-scale organization with 22 offices located throughout the Mid-Atlantic, Midwest, and Southeast regions.


Our decentralized approach allows us the freedom to execute business strategies that will benefit our clients the most. Autonomy is accompanied by teamwork and mutual respect among our offices. The “GTA Experience” is the glue that binds our regional offices together and helps guide our path to becoming one of the United States’ highest performing geotechnical and environmental firms:

Building Character

Our relationships are built upon the foundations of honesty and integrity with clients, employees, and vendors. Our team maintains the highest character with every interaction.

Creating Success

We attract, retain, and promote a diverse blend of high achievers who delight in the opportunity that accompanies growth. Our people are challenged to reason objectively and think independently to solve complex client problems efficiently and practically.

Client Focused

We are passionate about creating value for clients in a professional and disciplined manner. Our people truly listen to clients, diagnose the client problem, and provide solutions that achieve effective outcomes.


We collaborate with our clients to offer creative solutions that overcome barriers and respect budgets and deadlines. Our autonomous offices have local teams that are empowered to be responsive to local client and market demands.
