Who We Are
At uNITE Sleep Institute, we believe great sleep has the power to transform lives. That’s why we tore up the rulebook and started fresh—with care that feels calm, personal, and fast.
Most sleep centers make you wait weeks, sometimes months, just to get answers—and even longer to start treatment. We don’t think that’s okay. At uNITE, patients move through the process in days—from seeing a provider, to getting tested, to beginning treatment. Because the sooner you sleep better, the sooner life feels better.
Our spaces are designed to help you breathe easier the moment you arrive. Our providers actually take the time to listen. Every study is interpreted by board-certified physicians. Every patient is guided with clarity. And every referring provider gets the fast, accurate results they need to take the next step with confidence.
Co-founders Ty Windfeldt and John Hickok bring decades of healthcare leadership—but more importantly, a belief that healthcare doesn’t have to feel like healthcare. With advanced diagnostics, compassionate care, and an obsession with delivering happiness, we’re building a sleep experience that’s refreshingly different.
Better nights. Brighter days. Without the wait.
