Mark Sohl has taken on some of the toughest IT and business transformation challenges in Atlanta over the past 23 years. Starting his career as a stripper at Delta Air Lines (a paint stripper) in 1980, Mark was instrumental in turning around Delta’s European Operations and its Revenue Management organization, transforming Delta’s outsourced IT division into Delta Technology, accelerating CheckFree’s e-Bill product line sales & implementations, transforming AutoTrader.com delivery of technology solutions and, most recently, salvaging a failing mortgage company.  Mark is viewed as a change agent that can take on any challenging assignment and deliver results in a very professional, respectful and calm manner.
