Brookdale Senior Living Solutions owns and operates retirement homes across the United States. The company was established in 1978 and is based in Brentwood, Tennessee. It is the largest operator of senior housing in the United States, with over 51,000 residents as of December 31, 2025. In the late 1990s and early 2000s, Fortress Investment Group became the majority owner of Brookdale, holding approximately 51% of its share. In 2021, a New York Times investigation revealed that Brookdale submitted wrong and manipulated data to the government, thus inflating ratings of the quality of care in Brookdale's facilities. Shortly thereafter, the state of California filed a lawsuit against Brookdale alleging that the company manipulated the federal government’s nursing-home ratings system. Brookdale's headquarters remain in Tennessee, but a recent acquisition has made Milwaukee, Wisconsin their second largest office. Wikipedia
