ResCare Community Living

ResCare Community Living's Top Stability & Growth Strengths

Strong Market Position & Advantage: RCL operated at national scale and, following its March 31, 2026 sale, now sits within Sevita, which regulators and industry coverage repeatedly describe as the largest U.S. provider in IDD community-based services; required FTC divestitures further underline the combined platform’s market heft.
