Group Listing

I want to create a group listing for my members that need it. I want to create a listing for groups of people that work under the same business. How would I do this?

Example: Massage Envy has multiple Massage Therapist who work for them. I want to be able to display Massage Envy as a main listing. If you were to click on Massage Envy than you can view a listing of the massage therapists who work their.
