About Rob Hosack

Hosack previously worked for Cobb County Government for more than 29 years. He joined the county in 1986 as a planner in the Planning and Zoning Division. He also served as a senior planner, coordinator for intergovernmental relations and planning division manager. Rising through the ranks, Hosack was appointed as director of the Community Development Agency and served in this role for 15 years. In this capacity, he prepared the county’s first comprehensive development standards document, implemented administrative variances to assist with environmental compliance initiatives, administered the one-stop development review process, created the region’s first inventory of redevelopment sites and prepared the county’s Redevelopment Overlay District. Hosack was also the lead county representative in the creation of the Town Center Community Improvement District.

Hosack is a nationally-certified planner with the American Institute of Certified Planners and a certified public manager from the University of Georgia, through the EXCEL class of 1991. He is also a graduate of Leadership Cobb. Hosack has earned many honors and awards, including being named “Outstanding Young Public Servant of the Year” in 1992 by the South Cobb Jaycees, the 1999 “Golden Goose” award presented by the Board of Commissioners and county manager for excellence in management, the 2001 “Silver Eagle” award presented by the Cobb County management team for performing his job in a consistently superb manner and the 2002 “Executive of the Year” award from Cobb County’s Executive Support Professionals organization. Hosack was also selected for the Cobb Chamber Honorary Commanders Program in 2001.

During a brief retirement from Cobb County, he operated a small management and development consulting business, assisting both private sector and government clients. Hosack currently serves on the Kennesaw State University advisory board for the Master of Public Administration program. In January, he also began serving a four-year term as district supervisor with the Cobb County Soil and Water Conservation District and the Georgia Soil and Water Conservation Commission.

Hosack earned a Bachelor of Science degree in planning from Western Carolina University and began his career as a community planner for the State of Tennessee. He and his wife Coleen live in northeast Cobb and have three children.


Cobb County's Mission:

To make Cobb County the best place to live and work through efficient, effective and responsive government that delivers quality services.

We were both honored and challenged when a Atlanta Journal-Constitution poll of metro business and government leaders found that Cobb County was "best in delivering government services."

After all, this is a growing county, already Georgia's third largest. Which means the Cobb management team must continually fine tune methods and raise standards to preserve the high service level our taxpayers expect and deserve.

So, in keeping with this philosophy, we're pleased to present the Cobb County Government Web site. It's our hope to provide a convenient, useful resource for information about this showcase community.

For example, Cobb's water department is considered the best in the nation, our roads program is a regional model, our financial strength ranks Cobb among the nation's top one percent of all counties...and the list goes on.

Certainly, these are points of pride. But they're also challenges we're working hard to meet.

Best wishes,

Rob Hosack
County Manager
