Tynan Dillon was founded in Dublin in 1952 by Pat Tynan and Sean Dillon. Over the years, the firm operated from various addresses and is now located at 74 Northumberland Road, Dublin 4. Sean Dillon’s son, Barry Dillon, joined the firm in 1976, trained, and became a partner. Barry’s son, Conor, later joined as a partner, along with other new partners, before the Dublin office became part of the Xeinadin group.
Barry Butler joined the firm in 1966 and became a partner after qualifying. Due to the firm's growing client base in County Mayo, they opened an office in Ballyhaunis in 1979, with Barry as the resident partner. After Barry’s passing in 2006, Rosaleen Harrison took over management of the office and became a partner in 2011.
In 1974, Charlie McCreevy, after training in Dublin, opened the Naas office and served as the resident partner. Liam Murphy joined the firm in 1982, becoming a partner in 1986. Following Charlie’s appointment as a government minister in 1991, Liam became the sole resident partner until 2011, when Teresa Wall and Joseph O’Rourke, who had trained with the firm, were appointed partners.
