My office is in a house called "South Hall" on the campus of Woodmont Christian Church.
The church is on the corner of Woodmont Blvd. and Hillsboro Pike.

If you use a map service (i.e. mapquest or google) be sure you are going to the intersection of Woodmont and Hillsboro.
It is the white church with the really tall spire. 
The house is on the south end of the church campus closest to Green Hills Mall. 
The address is: 3605 Hillsboro Pike, Nashville, TN 37215
