Twenty-one years ago, Reeve B. Waud launched what would become the largest standalone behavioral healthcare company in the United States. Acadia Healthcare, founded in 2005, has grown from a startup platform into an organization operating 278 facilities across 40 states and Puerto Rico. That growth trajectory reflects both the increasing demand for behavioral health services and the disciplined approach Waud brought from his private equity background.
The January 2026 appointment of Debbie Osteen as CEO-her second stint leading the company-provides an opportunity to examine how Reeve B. Waud shaped Acadia’s development and why he remains central to its governance as Board Chairman.
From Startup to Industry Leader
Reeve B. Waud founded Acadia Healthcare as a platform for inpatient behavioral health facilities. His experience at Waud Capital Partners, the Chicago-based private equity firm he established in 1993, informed the company’s growth model.
The approach centered on identifying a fragmented healthcare sector with strong demand fundamentals, then building scale through both organic growth and acquisitions. Acadia went public in 2011, just six years after its founding-a timeline that demonstrated the market opportunity Waud had identified.
By 2025, Acadia had grown to employ approximately 25,500 people and serve more than 82,000 patients daily. The company’s payer mix reflects broad accessibility: 57% Medicaid, 26% commercial insurance, 14% Medicare, and 3% self-pay and other sources.
Two Decades of Growth Under Waud’s Guidance
Throughout Acadia’s expansion, Reeve B. Waud maintained an active role in governance. His firm, Waud Capital Partners, has completed more than 500 acquisitions across its portfolio companies, and that deal-making experience translated to Acadia’s growth through facility additions and health system partnerships.
The company now operates 52 acute care facilities, 35 specialty treatment facilities, 164 comprehensive treatment centers, and 9 pediatric residential treatment facilities. Joint venture partnerships with health systems including Henry Ford Hospital, Geisinger Health Systems, and Nebraska Methodist Health System expanded Acadia’s reach into communities served by established regional providers.
A New Chapter with Familiar Leadership
Osteen’s return to the CEO role connects directly to the leadership framework Reeve B. Waud established. During her first tenure from 2018 to 2022, Osteen led what the company described as “a period of significant progress and evolution.”
Waud’s statement announcing her appointment emphasized institutional knowledge: “Debbie is the right person to step into the CEO role while the Board conducts a comprehensive search for a long-term successor and continues to evaluate all paths to deliver enhanced shareholder value.”
For Acadia Healthcare, the combination of Waud’s founding vision and Osteen’s operational experience positions the company to continue serving patients across its nationwide network.
