The city sits 25 miles from our Alpharetta headquarters with direct I-75 access, making it one of our most accessible major markets. Cobb County's population of over 780,000 and its position as a business-friendly suburban market have generated consistent commercial real estate growth and a corresponding demand for professional janitorial services across every facility type.
