John Tomlin, CEO

John is a graduate of the Wharton School, past CEO of AAA Auto Club South, and an active community leader. He spent the past 26 years developing a rapidly growing sales force at AAA. Starting with the belief in total transparency and an agent-centric culture, the sales force grew from 35 agents to over 350. This growth was the result of careful hiring, solid training, ongoing mentoring, and technology that simplified the process for agents. He then separated selling from servicing clients. This allowed sales agents to do what they do best while the team provided outstanding service for clients. John brings a similar innovation to TSC to enable each agent to achieve their potential.
