Tillinghast Licht LLP was a Providence, Rhode Island based law firm, from 1818 to 2008. Established in 1818 by Charles Foster Tillinghast, Sr., a scion of one of the oldest families in Rhode Island, it was one of the oldest law firms in Rhode Island. In 1816, Tillinghast was admitted to the Rhode Island bar and opened his first office, in the village of Chepachet. The following year, he returned to Providence and partnered with Samuel W. Bridgham, under whom he had studied at Brown University. Six years later, Tillinghast opened his own office.
