The History of BIA

For over half a century, since its creation in 1963 by John Brock, Jr. and Marie Davis, the Brock Insurance Agency [BIA] has instinctively fostered the American Dream by providing access to commercial insurance, personal home and auto coverage, surety bonds and employee benefits when other agencies wouldn't or couldn't. By focusing on building relationships to truly understand and appreciate both the customer and their business, BIA has helped entrepreneurs in Chattanooga and the Southeast build startup companies into thriving enterprises. Not surprisingly, BIA continues to enjoy partner-like status with these now very successful business leaders. In 1969 Dana Davis, Marie's son, joined the agency.


Two decades later, in response to the passing of founder John Brock, Jr., sons Paul and Mark committed to fill the void by continuing the legacy. Their approach of strengthening existing relationships through careful attention to customers' current and future insurance needs continues to be the cornerstone and direction of the agency.  In 1998, DeFo Spencer joined the agency as President of the newly formed division, Brock & Spencer Benefits, to further service the needs of their clients by providing health and life insurance to employers and individuals. 

The first decade of the twenty first century saw the retirement of Marie Davis in 2004; the formation in 2007 of Brock & Spencer Benefits, LLC led by DeFo Spencer, who continues to partner with BIA; and the passing of Paul Brock in 2008 who had served as president of the agency since 1983 and the additon of Ketih Davis, Justin White, Trae Vaughan and Ramsey Brock. The fall of 2014 BIA opened their downtown Chattanooga office. In December of 2015 Vice President Dana Davis retired after 47 years with the agency. Today's partners, President Mark Brock, VP of Commercial Lines Trae Vaughan, VP of Personal Lines Keith Davis and VP of Marketing & Operations Ramsey Brock the future of the agency is in good hands.  


Over the last fifty plus years BIA has seen continued growth in all departments. As the agency grew so did its capacity to service its customers. Specialized divisions were created as apart of our strategic business model to bring expertise where "General Agent" became a thing of the past. Our customers needed and still need an agency who can bring forward thinking solutions, technology and efficiency to their bottom line. Our model is built to be flexible so that we can make in house decisions to ensure our cutomers, staff, agency and community are taken care of.
