Armstrong recently contributed to the renovation of an historic hospital in the Chicago area. From the early 1900s to the 1980s, Cook County Hospital was a leading healthcare institution. Patients used to travel from countries around the world for the innovative treatments and advanced care available. Many of the people now living in the Chicago area were born at Cook County Hospital, in the 1950s, 60s and 70s. Although the many professionals who served in the hospital were leaders and innovators in the field of healthcare, the building facility and the mechanical systems were not up to the demands of a modern healthcare facility setting. The original design had no cooling system, and the scale of renovations required to bring the facility up to modern standards made the prospect unaffordable. The hospital was closed in the 1980s and stood vacant for almost 30 years.
