Founded in 1974 by Sandy Tinsley, with little more than a typewriter and a desk, Tinsley Advertising has grown into one of the largest independent agencies in the Southeast. SandyÍs desk is a little bigger now, but she still sits behind it every day, presiding over an enviable roster of regional, national and international clients, as well as a team of some of the nationÍs best creative and strategic thinkers.
