Willis Insurance Agency is one of the areas oldest businesses. The agency was established in 1887 by C.D. Manley and called Manley Insurance Agency. Manley was a one-time County Clerk in Barry County. June 1, 1919 Charles Willis came to Cassville and began his insurance career with the agency. Upon the death of Mr. Manley in 1932, the business became Willis Insurance Agency and has continued doing business under that name. We are conveniently located in downtown Cassville on the Southeast Corner of the square. In April 2014, Willis Insurance purchased the Shell Knob Insurance Agency located in the Bridgeway Plaza. We now have two convenient locations to better serve the area.
