Some ways to find a previous teacher include contacting the school to find out if the teacher still teaches there, contacting teacher associations, contacting retired teachers organizations and searching online for the teacher's name. Alternatively, you can pay an online search company or hire a private detective.
Another way to locate a previous school teacher is to search online telephone and email directories.
Genealogical and family history sites can also be helpful when trying to find a previous school teacher. These sites may have address directories, marriage records, death records and obituaries that can help you find the whereabouts of a teacher.
