We asked for their help with a substantial wildlife survey that we knew would be very difficult, and their performance was exceptional. The Passarella & Associates team not only completed it, but also finished it more quickly than anyone thought possible. The staff is thorough, knowledgeable, very professional and widely respected by the agencies."

Leslie D. Alderman, Jr., Managing Partner, Florida Panther Conservation, LLC

"Florida Panther Conservation, LLC’s Habitat Conservation Bank was the first bank to be Approved and Certified by the U.S. Fish and Wildlife Service in Florida and the first in the Nation for the Florida panther. Approval of our bank would not have been possible without the knowledge and reputation earned by the professionals at Passarella & Associates. As our lead consultant, they were always “ahead of the curve” in anticipating the needs and demands of the Fish and Wildlife Service at the State, Regional and National levels. Passarella’s project management skills are exceptional. Because of their expertise, we were able to bring this “first time” project in on time and budget."
