Grubb Cottages are part of the Ross Campus Residential Treatment Foster Group Care program.

Grubb cottage includes three separate wings. Grubb West and Grubb East were built in 1985, and Grubb South was added in 2000. The Grubb cottage was designed specifically to provide greater staff supervision capabilities. Each Grubb cottage includes eight enhanced beds for youth who require high levels of supervision and who are working to return to living in the community.
