What is Third Rock Consultants?

Third Rock Consultants is an environmental consulting firm founded in 2000 by Molly Foree Cummins, a licensed environmental attorney with a background in environmental planning and design. Based on its own description, the firm serves clients across the Southeastern United States and combines ecological, engineering, planning, and permitting expertise in one practice. It is a fit for organizations that need help with ecological surveys, stream and wetland restoration, environmental permitting, stormwater (MS4) program management, erosion and sediment control, or aquatic taxonomy—particularly in Kentucky, Tennessee, Georgia, Illinois, Ohio, and North Carolina, where it holds DOT consultant prequalification.

What services does Third Rock Consultants provide?

The firm's stated service lines fall into six areas:

• Ecological surveys and analyses — field study of species, habitats, and aquatic systems.
• Stream and wetland restoration design and construction — design through build for damaged or regulated waterways and wetlands.
• Environmental planning — including 401/404 permitting, NEPA documentation, and feasibility studies.
• MS4 program management and permit monitoring — support for municipal separate storm sewer system compliance.
• Erosion protection and sediment control planning and inspection — plans and field inspection for construction-phase stormwater controls.
• Aquatic taxonomy — identification and classification of aquatic organisms, typically supporting biological assessments.

These services cluster around regulatory compliance and ecological restoration, so the firm is most relevant when a project touches waterways, wetlands, federal permits, or stormwater obligations.

Who works there?

Third Rock describes its staff as a collaborative of people with diverse environmental specialties. The listed roles include:

• Ecologists
• Professional engineers
• Professional geologists
• Environmental planners
• Construction inspectors
• Technical writers
• GIS analysts
• AutoCAD technicians

That mix matters for projects that need both field science and design/permitting work under one roof—for example, a stream restoration that requires ecological survey, engineering design, permit documentation, and construction inspection.

Who are its clients?

According to the firm, clients range from federal, state, and local agencies—including the US Army Corps of Engineers and the Environmental Protection Agency—to large and small consulting engineering firms, commercial and industrial entities, attorneys, and natural resource and environmental advocacy groups.

Certifications and geographic reach

Third Rock states it holds current certification as a disadvantaged business enterprise (DBE), small business (SB), and woman-owned business (WBE) through various federal, state, and local agencies. It also maintains DOT consultant prequalification in Kentucky, Tennessee, Georgia, Illinois, Ohio, and North Carolina.

Those certifications can matter if your project has supplier-diversity goals or requires a prequalified consultant for state DOT work. The prequalification list is also the clearest signal of where the firm is set up to take on transportation-related environmental work.

Is Third Rock Consultants a good fit?

Consider the firm when your project involves:

• Stream or wetland impacts requiring 401/404 permits or NEPA documentation
• Ecological surveys or aquatic taxonomy as part of an environmental assessment
• MS4 stormwater program management for a municipality or institution
• Erosion and sediment control plans and inspections on a construction site
• A need for a DBE/SB/WBE-certified environmental consultant in the Southeast

Look elsewhere if your needs fall outside environmental consulting—for example, general civil design unrelated to environmental permitting, or work in regions where the firm does not list prequalification. Because pricing is not published on the site, budget and engagement terms would need to be confirmed directly with the firm.
