Cornerstone has evolved from a small General Agency (GA) concept to the multi-carrier full service insurance brokerage firm that it is today. John Carroll, CEO, originally formed Carroll and Associates in 1985. Carroll and Associates eventually changed its name to Cornerstone and committed itself entirely to wholesale brokerage in Greater Cincinnati. Carrier contracts were executed and software was developed to facilitate the generation of proposals, tracking and reporting of all case activity, as well as the processing of commissions.
