Weekday birthday volume in Ridgeland is suburban white-collar rather than civic, and almost all of it sits on two roads. Highland Colony Parkway is the spine: Butler Snow LLP is headquartered at 1020 Highland Colony Parkway, C Spire at 1018, and BankPlus keeps offices on the same corridor, with accounting firms, insurance agencies, engineering consultancies, wealth-management shops and medical administration filling the low-rise office buildings between them. Renaissance at Colony Park stacks professional suites above and behind its retail row, and The Township at Colony Park does the same a little further south — both are multi-tenant, both route by suite number, and neither has a single central mailroom, so a driver who is handed only a company name loses time walking the sidewalk. Northpark on East County Line Road adds mall management, tenant back-offices and a heavy retail payroll whose birthdays land on odd shifts. Olde Towne on Highway 51 is the older, smaller-business side of the same economy — law offices, dental and orthodontic practices, salons, Ridgeland City Hall at 304 Highway 51, the police and fire administration, and the Ridgeland Public Library a few doors along. Holmes Community College keeps its Ridgeland campus on West Ridgeland Avenue, where faculty and staff birthdays route through department offices. Inside the same 60-mile radius the list widens to Trustmark at 248 East Capitol and Entergy Mississippi in downtown Jackson, Blue Cross & Blue Shield of Mississippi on Lakeland Drive in Flowood, the Mississippi Farm Bureau Federation on Ridgewood Road, the University of Mississippi Medical Center on North State Street, the Nissan assembly plant in Canton and Continental Tire in Clinton. One practical rule covers all of it: put the recipient's full name, the building, the suite number and the company in the gift note. Ridgeland office parks are signed by address, not by tenant.
