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 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. He has held various positions as VP, SVP, CIO, and COO in various organizations including IT, Operations, Servicing, Professional Services and Marketing. He credits his success with this advice; focus more on your customer than yourself, build trusted relationships, and always be honest, open and transparent in everything you do.  Mark is now at The Rainmaker Group, a leading provider of revenue management analytics for the Hospitality and Multi-Family industries. Back in the revenue management arena, Mark is leading the IT Development efforts and managing the Airline Solutions group.
