Our
difference

Full service

With specialized subject matter experts and experienced inspection teams, D3G provides a full-spectrum of services ranging from Environmental Review and UST Removal to Radon testing and National Environmental Protection Agency (NEPA) consulting. We work with you from concept to closing.

Contamination Experts

We tackle the most challenging projects across the country. We have successfully guided many property owners and lenders through the process of evaluating and mitigating risk. Our staff has experience in nearly 50 states obtaining No Further Action letters from local environmental authorities to ensure that your property is within full compliance.

Leadership

D3G is often selected to pilot new or difficult environmental reporting platforms as the “industry experts.”  Most recently, HUD selected our firm to test the HUD Environmental Review Online System (HEROS).
