About Us

Governmental Management Services (“GMS”) is a family of limited liability companies that were established for the purpose of providing special district management services to community development districts. GMS was created to provide a meaningful alternative to then existing district management companies.

Governmental Management Services currently has primary offices in Knoxville, Tennessee; Jacksonville, Florida; St. Augustine, Florida; Ft. Lauderdale, Florida; Orlando, Florida; Palm Coast, Florida; and Tampa, Florida with supporting offices from Tallahassee, Florida to Miami, Florida.

Many of our team members have worked with Investment Bankers, Bond Counsels, District Counsels, Engineers, Developers and Boards of Supervisors across the State of Florida. They have been providing management, financial and administrative reporting services to Special Taxing Districts and/or Homeowners Associations during their careers.

The goal of GMS is to provide the most efficient, effective and comprehensive management services for Community Development District’s in the State of Florida. Governmental Management Service’s greatest strength is its ability to respond to individual client needs quickly, efficiently and professionally.
