Our Corporate Clients


Kind words from our clients.

Kay Pentzien

Real Estate Developer

The A3 Environmental Team completed both a Phase 1 and a Phase 2 for our property and Patrick and I couldn't be more pleased with the work they did!

Ross DePaul

Mergers & Acqusitions

I thoroughly enjoyed working with A3E on our Phase 1 studies. We were running up against some deadlines, and they jumped through hoops to get everything completed on time.

Daniela Fitzgerald


The A3E team did a great job on our Phase 1 report. They were quick , thorough and professional. They were able to give me all of the information that I needed.
