About Gas South

(Actually, it’s about something bigger than ourselves)

At Gas South, we’re driven by a simple mission: Be A Fuel For Good. It's not just a slogan on our website or conference room walls. It's our core belief that how we treat people is what's most important.

It's the way our CEO knows every employee by name. It's customer service folks who go the extra mile. It's the volunteer time our employees cheerfully contribute and the 5% of profits to support children in the areas we serve.

As our company grows, so does our impact. Since our 2006 inception, we’ve grown steadily to become not only the largest retail natural gas company in Georgia but also the largest in the Southeastern U.S. We now serve more than 425,000 customers in 14 states.
We've formed Alliance Partnerships with local governments and utilities across Metro Atlanta, helping customers save on their natural gas.
Keeping our “5% back” promise, we’ve also given back more than $9M to local causes (and counting).
Our Leadership
Kevin Greiner
President and Chief Executive Officer
Kevin Greiner - President and CEO

Whether you've been an employee since the beginning or you've worked here a month, Kevin Greiner is all about discovering what’s important to people—starting with never forgetting your name. We're not sure how he does it, but we're glad he does. At the office, Kevin won't hesitate to chat with you about what you're up to or the latest tennis highlights—he genuinely cares about every employee.

He's also passionate about strengthening our community. Under Kevin’s leadership, Gas South has committed to giving 5% of profits to support children in need. He’s built a culture of service while also creating exceptional career paths for employees. He wants to make sure Gas South is a place where people want to be, not a place you feel like you have to be.

With more than 20 years' experience in the energy sector, Kevin gained expertise in management roles with Southern Company and ill-fated Enron (please don’t hold that latter experience against him!). He graduated from the University of Michigan with a master's degree in business administration and a Master of Science in natural resource policy and earned a bachelor's degree from Wesleyan University. In recognition of Gas South’s growth and corporate citizenship, Georgia Trend magazine named him Georgia’s most respected business leader in 2021, and the Atlanta Business Chronicle named him one of Atlanta’s most admired CEOs in 2018 and 2021.
