“As a developer and general contractor of historic properties, we needed an environmental company that could perform Phase I’s, lead and asbestos surveys, sampling, monitoring and general counseling on our environmental issues.  Greenstreet Environmental was able to perform all of those tasks quickly and professionally.  Their reports were well written and provided the information needed for the regulatory agencies and banks.  What really sets Green Street Environmental apart from the other environmental consulting firms is their ability to provide no-nonsense solutions to our problems and explain what is actually required by code.  We have thoroughly enjoyed working with Scott and his team and look forward to many more years.”
