President and Chief Executive Officer

As President and CEO of IASIS Healthcare, Carl Whitmer provides the strategic vision, leadership and oversight that enable the company to fulfill its mission of providing high-quality, cost-effective healthcare through its acute care hospitals and managed care risk platform. When Whitmer assumed the company’s top leadership position in 2010 after having served the company as CFO, he brought with him many years of management experience, including 20 years in healthcare leadership and executive roles.

During Whitmer’s tenure as CEO, IASIS has expanded its footprint in new and existing markets, formed new local and national partnerships, and transformed its single-state managed health plan into a multi-state operation with adjacent business lines. Today, IASIS Healthcare is a $3.0 billion healthcare services company with 13,000+ employees and 17 acute care hospitals, one behavioral health hospital, multiple other access points, including 148 physician clinics, outpatient surgical units, imaging centers, investments in urgent care centers and on-site employer-based clinics, and Health Choice, IASIS’ managed care risk platform, which delivers services to approximately 624,000 covered lives through its multiple health plans, accountable care networks and third-party management and administrative services.

Prior to IASIS, Whitmer held the CFO, Vice President of Finance and Treasurer positions at PhyCor, Inc., a physician practice and IPA management company, and the senior manager role at KPMG LLP.

In addition to serving on the IASIS Healthcare Board of Directors, Whitmer serves on the boards of directors for NorthStar Anesthesia, the Nashville Health Care Council, and the Nashville Chamber of Commerce and as Chair-Elect of the Federation of American Hospitals.
