Two new medical buildings at Rancho Los Amigos National Rehabilitation Center were officially completed as part of a $418 million makeover of the Downey hospital.

Los Angeles County officials joined local leaders on Sept. 12 to celebrate the pending opening of a new Outpatient Building and expansion of the Jacquelin Perry Institute, which will combine the nearly 400 beds at the county-owned rehabilitation hospital under one roof.

The combined buildings, funded by the county Department of Health Services, comprise 72,000 square feet and are expected to open for patients this winter. County officials and hospital representatives weren’t able to immediately break down their respective size and costs

“The completion of these two beautiful new buildings marks a milestone for the county in assuring that individuals facing debilitating and life-changing illnesses, injuries or disabilities have access to the best, most advanced treatments available,” said Supervisor Janice Hahn, in a statement.

The 130-year-old rehabilitation hospital is now undergoing a $418 million Rancho Rising 2020 Renovation initiative that began in 2015 and is expected to be completed by 2020.

Apart from seismic safety improvements, the hospital for the disabled aims to consolidate patient services on its 49-acre campus. That means improving campus accessibility and health care for patients with spinal cord damage, brain injuries, orthopedic disabilities, stroke, as well as neurological, physical and developmental disorders.

“The new facilities will allow us to do even more to restore both the overall well-being and hope of our patients and put them on a path for rebuilding their lives,” said Aries Limbaga, chief executive of Rancho Los Amigos, in a statement.
