A Technical and Regulatory Advocate

In today’s ever-changing regulatory landscape, compliance with federal and state environmental laws is critical to the success of projects. Compliance can often seem at odds with the project vision and financial constraints. Our team partners with you as a technical and regulatory advocate to overcome obstacles and guide you through complicated policies to achieve your goals.

From initial investigations to final design, our environmental experts are there to assist in all facets of the project. Thrasher strives to provide our clients with the services and expertise needed to identify and minimize impacts to natural resources while avoiding costly project delays. Our trained staff combines the knowledge and understanding of the complexities of federal and state regulations with positive agency relationships for permit approvals and clearances required for project completion.

The diversity our team has in the natural resource field, in conjunction with their education, experience, and the ability to adapt to permitting and project needs, have allowed us to develop relationships with academic consultants from multiple universities to aid in performing specialized assessments.
