In 2024, Valleywise Health opened the new state of the art 10-story 240 bed Valleywise Medical Center on its Roosevelt Campus near downtown Phoenix. On June 26, 2025, the year-long demolition began on the iconic Maricopa Medical Center tower. On the November 4, 2025 general election, the voters of Maricopa County approved Proposition 409 - a $898 million Valleywise Health measure to expand behavioral health services, rebuild and expand Community Health Centers and to replace the Comprehensive Health Center. History Valleywise Health traces its roots back to 1877, when Arizona was still a territory. That year, Maricopa County opened a pest house to treat persons afflicted with communicable diseases. Valleywise Health is the direct descendant from this pre-statehood beginning of public health care in Phoenix and Maricopa County. In October 2018, the organization announced that it would change its name from Maricopa Integrated Health System a.k.a. "MIHS" to Valleywise Health effective mid-2019. Maricopa County's residents approved the formation of a Special Health Care District in 2003 which is the elected governing body that provides public oversight over Valleywise Health. The five members of the District's Board of Directors are elected by the citizens of Maricopa County and serve as public officials for a term of four years. A.R.S. §§ 48-5502; 48-5503.
