  • “Rimmer Environmental has played a key role in our project permitting over the last twenty years and has exhibited an outstanding ability to handle some of the most strenuously opposed project approvals. Mary’s extensive knowledge of wetland science and current regulations on federal, state and local levels is second to none, and her low-key approach has a tendency to disarm opposition, and build consensus.”

  • “Rimmer Environmental Consulting is our “Go To” firm for our wetlands delineations and environmental permitting assistance.  Working on over 50 projects together, their work is professional, on time, on budget, and most importantly, always meets the difficult test of public and municipal scrutiny.”
