As President and CEO, Bill Lathem is responsible for providing strategic guidance, maintaining a strong management team, and increasing shareholder value.

Bill Lathem is the fourth generation of his family to run the company, following in the footsteps of his father, Louie P. Lathem, Jr., his grandfather, Louie Lathem Sr., and his great-grandfather, George Lathem. Bill worked in various part-time positions throughout high school and college (he received his Bachelor of Science degree in Industrial Engineering from Auburn University). He then joined the company full-time in 1976 at age 22 to open the company's first branch office in California. Following that effort, Bill returned to Atlanta and worked his way up to President and CEO. His most challenging and significant accomplishment at Lathem has been to transform the company from a traditional manufacturer to a complete technology and service organization capable of delivering high-tech automated solutions to its customers.
