Our community (Greenspring in Springfield VA), has a salon in each of our 3 clubhouses. The community provides the salon space, however the salon staff is managed by "PS Salon". They specialize in providing salon services at Senior Communities. They also provide services at the AL facility where my moth-in-law lives and at the AL facility where my mother lived before she passed away.
I'm not sure of all the geography that they cover, but they serve about 1,500 locations.
