Prime Healthcare has entered into an asset purchase agreement with Franciscan Alliance to acquire Franciscan Health Olympia Fields, helping preserve access to high-quality, compassionate care for the South Suburbs of Chicago.

The proposed transaction would add the 214-bed Franciscan Health Olympia Fields and Specialty Physicians of Illinois, LLC to Prime Healthcare’s award-winning national system, which is recognized for clinical excellence, health equity, and social responsibility. Franciscan Health Olympia Fields has served the South Suburbs for more than two decades and is Franciscan Alliance’s only hospital in Illinois.

“Our agreement with Franciscan Alliance reflects Prime Healthcare’s enduring mission to save, strengthen, and invest in community hospitals while honoring Franciscan’s deep commitment to serving the poor and vulnerable,” said Sunny Bhatia, MD, President and Chief Medical Officer of Prime Healthcare. “We are grateful for the trust Franciscan has placed in us and are committed to stewarding this hospital with compassion, integrity, and a commitment to clinical excellence and compassionate care for all.”

As part of this proposed acquisition, Prime has committed mission-driven investments, including a $5 million philanthropic contribution to support medical education. Consistent with Prime’s long-standing practice, substantially all employees will be offered continued employment, and charity care and community benefit programs will continue.

Together, we look forward to continuing the shared mission of saving hospitals, saving jobs, and saving lives.
