Though officially founded a year earlier, Franklin-based IASIS Healthcare Corporation begins principal operations in October of 1999 thanks to $200 million from venture-capital firm New York-based Joseph Littlejohn & Levy, with David White at the helm.

In 2004, Texas Pacific Group, a private-equity firm, leads a group of investors to acquire IASIS and remains the single largest stockholder today.

IASIS files for an IPO in February 2015, becoming Nashville’s fourth publicly traded acute-care hospital company, joining LifePoint Health, HCA Holdings and Community Health Systems. The move leaves only Capella Healthcare and RegionalCare Hospital Partners on the private side.
