I teach within approximately an hour -- no more than an hour and a half -- of Fairborn, Ohio.
This includes the following counties:
My immediate area is Montgomery, Greene, Clark, and Miami.
I also serve Darke, Preble, Warren, Clinton, Fayette, Madison, Champaign, Union, Logan, and Shelby counties.
Services may be available in the counties surrounding that depending on distance (and proximity to I-75). Exceptions: I do not serve Butler, Hamilton, or Franklin counties.
