Dennis & Dennis was an architectural partnership in the U.S. state of Georgia which was Georgia's oldest architectural firm. It designed numerous commercial, institutional and residential buildings in Macon and other Georgia communities.
It was established by Peter E. Dennis (1854-1929) in 1884. Peter had attended the University of Georgia from 1871 to 1872 and had trained in the office of Algernon Blair in Macon, before leaving to create his own firm. The firm became "Dennis and Dennis" in 1912 when Peter's son John joined.
Dennis and Dennis designed two houses in the Shirley Hills Historic District's original listed area. The boundary increase added 271 contributing buildings and 24 contributing sites.
A number of their works are listed on the National Register of Historic Places for their architecture.
