We take on some of the most complex environmental permitting work in the United States.

Solving problems is our focus. HHNT has chosen to work with clients having the most difficult and complex permitting issues. On more than 500 landfill and surface mining projects, we have worked alongside our clients as part of their team, and our extensive experience gives us the unique ability to succeed where others fail.


We bring our expertise to every project, and share our clientele’s intensity for solving problems. This approach has set us apart as a successful environmental engineering design, consulting, and permitting firm for more than two decades.


We view every project as an opportunity to prove ourselves. That’s why a senior partner manages every project we undertake. When we look you in the eye and tell you we’ll do the job, we make sure it is done right to help your business succeed.
