The Maryland Homeschool Association hosts a series of service directories at mdhsa.com/directories. The directories offer free 1-line listings as well as paid featured sponsors who offer education-related services that would be of interest to Maryland families who educate their children at home. The free 1-line listings are offered to support groups, tutors, private teachers, and professional educational service providers, such as speech pathologists and occupational therapists, co-ops, and other small businesses. The directory lists individuals by name or business, along with the area of the county you are based in, a telephone number and an email address.
NOTE: At this time, umbrella groups are not eligible for a free listing in the MDHSA service directories.
