Two nonprofit behavioral health providers finalized the merging of their organizations at a ceremonial signing event in Springfield. Executives from Nashville-based Centerstone and Springfield-based Brightli signed a master transaction agreement (MTA) on Sept. 9, formalizing the merger of the two organizations to form the largest nonprofit behavioral health care provider in the United States. The merger is set to close in early November 2025.
Moving forward, the surviving entity, Brightli, will adopt the unified Centerstone name and brand. Centerstone’s 28-year legacy as a strong, trusted brand makes it the name of choice for the merged organization. Upon closing, Centerstone will employ more than 10,000 team members with physical operations in nine U.S. states. It will serve nearly 250,000 clients annually, with concentration in the Mid-South, Midwest and southeastern United States.
At the conclusion of the merger, Centerstone will be headquartered in Nashville, Tennessee. There are no plans in the merger agreement for executives or staff to relocate. Springfield will be the headquarters for Centerstone’s operations in Missouri, with administrative operations remaining on the Burrell Behavioral Health Administrative Campus on West Battlefield Road. Brightli CEO C.J. Davis says Missouri will be a state of focus for Centerstone’s long-term future.
“Brightli’s member organizations will be thoughtfully rebranded to Centerstone over a one- to two-year period,” Davis said. “With such a significant portion of our operations based here in Missouri, our commitment to this state runs deep. We will remain steadfast in providing high-quality mental health care to Missourians now and for generations to come.”
Following the merger’s closing in early November, David C. Guth, Jr. will be the Chief Executive Officer of the merged organization. Brightli CEO C.J. Davis will be CEO-elect, becoming the CEO in January 2027 when Guth becomes CEO Emeritus. Guth will then retire later in 2027 after having served the organization for 39 years.
“I am confident in the leadership and vision that C.J. brings to help continue the growth of Centerstone as a leader in the industry. He is guided by a deep mission of expanding care to the people in our communities,” Guth said.
“This merger of equals is not about the scale. It’s about the opportunity to lead during this critical point in the landscape of behavioral health services.” Guth said. “The need and public support for quality mental health care is at an all-time high, there is strong bipartisan support for mental health services at the state and federal levels, and stigma continues to erode.”
Davis agrees that behavioral health care in the United States is at an inflection point.
“Behavioral health is at a crossroads, and this partnership allows us to do more than respond to the immediate needs of today. It allows us to shape the future. By investing in research, raising the quality of care, and expanding access, we can save lives. We will strengthen communities in ways neither of us could do alone,” Davis said. “This is about making sure hope and healing are within reach for every person we serve, and I couldn’t be more hopeful about what’s ahead.”
“Both organizations are committed to advancing the science of care and the application of that science in real-world practice,” Guth said.
