Trivers Associates has a 40+ year history and historic renovation projects have been a primary focus of our work. We understand multiple agency review coordination and quality control in the careful specification of renovation work. We have dealt extensively with the National Park Service, the Advisory Council on Historic Preservation, the National Trust for Historic Preservation, and the State Historic Preservation Offices of many states. As a result, we are very familiar with the Section 106 process of public review, input and buy-in on work of this sort. We have offices in Missouri and Illinois, though our work and expertise in historic structures takes our team across the country.
