Thornton established himself as an architect in Olneyville (then part of Johnston) in the 1890s.[1] He remained there until about 1900, when he formed a partnership with Richard C. Sanders, another young architect, in central Providence. Sanders & Thornton was dissolved in 1902, and Thornton partnered with his cousin, Henry C. Thornton.[2] They split about 1903, when Henry left to partner with his brother-in-law, Edwin T. Banning. However, Thornton continued as Thornton & Thornton until his death in 1911.
