How Dr. Jimmy Gardiner and Liminal Solutions transformed a four-practice operation into Northern Alabama's largest privately held dental support organization.
“It shifted from me pulling everyone along to all of us pushing together. That’s when everything changed.”Dr. Jimmy Gardiner — CEO & Founder, Singing River Dental Partners
In February 2018, Dr. Jimmy Gardiner and Dave Salciccioli met at a DEO conference in Philadelphia. There was no formal engagement on the table—just two people who recognized in each other a shared conviction about how organizations should treat people.
Dr. Gardiner was running four dental practices across Northern Alabama under what would eventually become Singing River Dental Partners. He had built something real, but he knew the way he had built it couldn’t carry him where he wanted to go.
That initial conversation became a coaching relationship, and the relationship became a five-year strategic partnership that would reshape the entire organization.
Dr. Jimmy Gardiner
CEO & Founder, Singing River Dental Partners
In 2019, Singing River Dental Partners was a $7 million organization operating four locations. On paper, it was successful. Behind the scenes, it was a founder doing everything.
Hard conversations were avoided. Roles and responsibilities were undefined. Whenever there was a disagreement among senior leaders, the decision would stall—and everyone would look to Dr. Gardiner.
Dr. Gardiner didn’t just want more locations. He wanted leverage—on the problems that consumed his time, on the decisions that shouldn’t require a CEO, and on the leadership gaps that kept the organization tethered to a single person’s capacity.
The work began not with the organization, but with its founder. Before systems could be built or teams restructured, Dr. Gardiner needed to look inward—developing self-awareness and building the courage to have hard conversations through intentional training, coaching, and practice.
As Dr. Gardiner’s leadership evolved, coaching expanded to include key team members. One of the most counterintuitive moves: reducing the leadership team. Fewer leaders, but more capable ones. The result was better culture, sharper decision-making, and an organization that no longer needed its CEO in every room.
As trust deepened, Dave’s role evolved from coach to strategic operator. The engagement expanded to include systems architecture, acquisition integration strategy, and operational infrastructure—the frameworks that would allow Singing River to scale with confidence.
Difficult conversations about who was equipped to grow with the organization. Hiring experts instead of generalists. Creating a culture where poor cultural fit is no longer tolerated, regardless of clinical skill.
Comprehensive SOPs and playbooks for every workflow. Monday.com as the backbone for task management. Morning huddles, standardized insurance processes, financial systems, and digital dentistry models. The infrastructure that made growth absorbable.
From limited financial insight to real-time dashboards and daily reporting. Leaders at every level gained the data—and the confidence—to make informed decisions without escalating to the CEO.
Between 2019 and 2024, five acquisitions and integrations—Helton, Madison, TH Madison, Athens (de novo), and TH Killen. Each proving the model could absorb growth without breaking.
A defining strategic moment was the creation and launch of the Treehouse brand—a pediatric-focused network born from Dr. Gardiner’s vision to provide high-quality dental care to children across the region. Two additional practices were added to create a regional network of children’s dental care.
The entity structure was evolved to make associate dentist partnerships possible for the first time, positioning Singing River as Northern Alabama’s premier dental support organization—and the largest privately held DSO in Alabama.
The leadership team that emerged bears no resemblance to the one that existed in 2019. Leaders are more proactive, more intentional, and more willing to engage in the hard conversations that used to be avoided. Every member has stepped into bigger ownership as the structure became clearer.
Now the largest privately held Dental Support Organization in Alabama, Singing River Dental Partners is faster, more resilient, and more courageous than it was five years ago.
