Marcel Quimby, FAIA

Her experience ranges from complex restoration projects such as the Newton County Courthouse, which will be substantially reconstructed, to extensive historic resource nominations such as the Downtown Dallas National Register nomination.

Also in downtown Dallas, she has prepared a preservation plan for Dallas’ historic Municipal Building and served as the preservation planner for the Downtown Parks Master Plan. Her work experience includes the development of ordinances, training for Landmark Commissions and the preparation of preservation criteria for numerous cities across Texas. She is a former Landmark Commission member and has served on its Designation Committee for over twenty years, is a former Advisor to the National Trust for Historic Preservation and a former President and active member of Preservation Dallas and AIA Dallas.

Nancy McCoy, FAIA
Nancy is an award-winning preservation architect with national experience. She has a broad range of project experience that includes highly complex $100 million projects such as the adaptive use of Kansas City’s Union Station and more intricate conservation work associated with the preservation of historic murals at Fair Park in Dallas. She has designed additions and the rehabilitation of the Department of the Interior Building in Washington, D.C. as well as for smaller structures such as a Charles Dilbeck-designed residence, now called Paigebrooke Farm.

Her strength is in designing a balance between the conservation of historic resources and modern-day safety, function and aesthetic goals for the continued use of historic buildings. She currently serves as Treasurer of the Association for Preservation Technology and as Chair of the Historic Resources Committee of the AIA Dallas. She has practiced in New York and in Washington, D.C. prior to moving to Dallas in 1997. The interpretation of the Secretary of the Interior’s Standards—the philosophical basis for historic preservation—has been a career-long interest that continues with each project.
