The people who serve the people who serve our customers.

Our leadership is driven to create an environment for our team that empowers each member to perform at the highest possible level.

Steven Tomlinson

Managing Partner

Steven grew up in Waycross, Georgia and graduated from the University of Georgia. He founded Level Seven in 2012 on the belief that success in business begins with an exceptional workplace culture: When our people love working with us, our clients love working with us, too. By emphasizing enjoying what we do as one of our core principles, Steven has surrounded himself with a team of the highest-caliber people who are empowered to lead with their own individual strengths. He’s particularly proud of our extraordinarily low turnover over the years, a testament to what kind of company Level Seven is. In addition to his work, Steven enjoys time with his family, wandering in the woods, and making his (not quite) world-famous hot sauce. 

Dave Hollister

Managing Partner

Dave grew up in the metro Atlanta area and graduated from the University of Georgia. He joined Level Seven early in its formative years after working 15 years in the landscaping industry. Shortly thereafter, he acquired a 50% equity position in the company and has been the primary architect of its operations ever since. Dave believes the key to our success is consistent, exceptional service, which is achieved with clear communication and effective, repeatable systems. He is big on process, collaboration, and operating with a high degree of personal integrity in everything we do. When he’s not thinking about ways to improve Level Seven, you can catch him playing golf, spending time with his family, taking in a Dawgs game, or seeing some live music.
