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.
