Onos’ Behavioral Health Advisory Board

We believe the key to making healthcare more affordable and higher quality is by transforming how payers and providers collaborate, so that manual work is minimized and proactive clinical decision making is prioritized.

Our AI-powered behavioral health platform transforms complex clinical documentation into actionable, source-linked intelligence that health plans can use to better understand quality and utilization. By providing clear, evidence-based insights, Onos enables health plan clinical teams to engage providers more effectively, identify opportunities for improved care journeys, and ultimately help deliver higher-quality, more affordable care.

Our proprietary AI models create advanced clinical infrastructure built around robust actionable intelligence. Developing and applying these capabilities requires clinical expertise, trust and thoughtful stewardship of artificial intelligence. At Onos, we are committed to a human-in-the-loop approach that ensures AI supports clinical decision-making rather than replaces it. Every insight generated by our platform is designed to empower healthcare professionals with greater clarity while preserving the human judgment that remains essential to delivering quality care.

That commitment is one of the reasons we have established Onos’ Advisory Board. Comprised of nationally recognized leaders in behavioral health, health plan operations, public policy, and clinical innovation, the board provides strategic guidance on how Onos can responsibly apply AI to help health plans and providers work more effectively together. Their collective experience spans organizations responsible for hundreds of millions of covered lives and some of the most significant advancements in behavioral healthcare over the past several decades.

As healthcare continues to evolve, their expertise helps ensure that we remain focused on what matters most: enabling collaboration between payers and providers, improving clinical quality, expanding access to effective care, and making healthcare more affordable for everyone.

Why Their Guidance Matters

The future of behavioral healthcare will not be built by technology companies alone. It will be built through partnerships between clinicians, providers, health plans, policymakers, and innovators who share a common goal: better outcomes at a sustainable cost.

Onos’ advisors have spent their careers leading these efforts. They understand the complexities of behavioral health from every angle, from clinical care delivery and utilization management to quality measurement, policy, provider engagement, and health plan operations. Their guidance helps ensure that Onos develops AI solutions that are clinically credible, operationally practical, and aligned with the real-world challenges facing health plans and providers.
