Top rated public schools, scenic rolling hills, and a diverse business community are some of the reasons why Williamson County is enjoying its present rapid growth. Williamson County is home to Brentwood, Franklin, Spring Hill, Nolensville, College Grove, Thompson Station, Leipers Fork, and Fairview.

Williamson County has been ranked as the 11th wealthiest county in the United States, yet retains a warm and welcoming demeanor which makes it a prime destination for families moving from other places.
