​Senior Leadership Team
Casey Brown
CEO
Casey has launched and operated residential real estate firms, property management firms, mortgage brokerages and title companies across four states within the South East.  He entered the business as a sales associate in the late 1990’s and joined the management team shortly thereafter.  Casey spearheaded the opening of offices in new markets for three years before venturing out on his own to start his first firm in 2001 and Reliant Realty in 2004.
 
Rapidly evolving technology combined with emerging legislation and unparalleled market swings and pressures caused the industry to evolve more in the last decade than ever before.  Growing firms during such a dynamic period provided the unique experience and insight that help guide our family of companies today.
 
Casey continually engages with and depends on our exceptional management team to continue driving our operation to new heights.  Inclusion and collaboration are keys to our success as we draw from the many talents and perspectives within the Senior Management Team.  All our present, past and future successes are the direct result of our remarkable men and women operating with a "team first" disposition that has been the cornerstone to each endeavor.

Casey serves on ERA's National Advisory Council and the Young Leaders Network that regularly meets around the nation, along with the Senior Leadership of ERA and Realogy, to consult on the trending and important aspects of today’s real estate landscape, while trading best practices and perspectives.  The insight gleaned from these associations has been invaluable.
