In 1933, B. Snowden Boyle, J. Bayard Boyle, and Charles Boyle founded Boyle Investment Company, a real estate and property management company. Shortly after, realizing the need for insurance services for their clients, they entered into an arrangement with a close friend and insurance agent, Marshall R. Yandell, to offer these services on a brokerage basis. This arrangement continued until after World War II, when the Boyles brought in a young Princeton graduate, James H. Wetter, to be trained by Yandell to head up the Boyle Insurance operation. It then became Boyle Insurance Agency, and Wetter was the agency's first president.
In 1972, Jack J. Craddock (1957) became president upon Wetter's retirement and remained so until his retirement in 1998, when W. Patton Steele took over the responsibilities of president. Upon Steele's retirement in 2009, Cynthia Gresham was appointed president. Boyle Insurance Agency, Inc. is primarily a property and casualty agency with about 80 percent of its volume in commercial lines.
