Mosaic Health Taps Doug Wenners as CEO to Drive Integrated Care Vision

NASHVILLE, Tenn. – May 21, 2026 – Mosaic Health today announced a significant leadership transition, appointing seasoned healthcare executive Doug Wenners as its new Chief Executive Officer. The move signals an aggressive push to accelerate the company's mission of building a national, integrated care delivery platform focused on digital innovation and improved patient outcomes.

Wenners will take the helm of the company formed in 2024, tasked with steering its next phase of growth. Clay Richards, who has led Mosaic Health since its inception, will transition to the role of Executive Chair. The company stated that Richards will remain actively involved, working closely with Wenners to ensure a seamless transition and maintain the platform's momentum. The appointment comes as Mosaic aims to deepen its focus on expanding its care delivery network, enhancing patient care quality, and leveraging digital technology to create a more connected and personalized healthcare experience for the nearly one million individuals it serves across 19 states.

A Strategic Architect for an Integrated Future

Doug Wenners brings a uniquely diverse resume that seems tailor-made for Mosaic Health's complex mission of weaving together provider organizations, payer-side strategies, and digital health solutions. His career spans leadership roles in health plans, provider groups, and innovative value-based care startups, giving him a panoramic view of the industry's challenges and opportunities.

Most notably, Wenners co-founded and served as CEO of Prospero Health, a home-based medical care provider for patients with serious illnesses, which he successfully scaled across multiple markets before its acquisition by UnitedHealth Group. This experience in building and expanding a specialized care model is directly relevant to Mosaic’s goal of serving higher-need populations. He also previously served as CEO of Optum at Home, further deepening his expertise within one of the nation's largest integrated health systems.

His tenure in senior leadership at Anthem, where he managed multi-billion-dollar business lines, provides him with critical insight into the payer landscape. At Anthem, he was instrumental in developing early value-based payment models and fostering provider partnerships, a core component of Mosaic's strategy. This blend of payer and provider experience is a rare and valuable asset in an industry striving for greater alignment between financing and care delivery.

"Doug's clarity of purpose, thoughtful leadership, and alignment with our values and culture make him the right leader to carry our mission forward," said Clay Richards, Executive Chair of Mosaic Health. "His vision for advancing patient-centered care, scaling our care delivery platform, and unlocking the full potential of our digital capabilities will be critical as we continue to redefine how people experience healthcare."

Weaving a Cohesive Care Platform

Mosaic Health itself is a bold strategic play, formed in August 2024 as a joint venture between private equity firm Clayton, Dubilier & Rice (CD&R) and insurance giant Elevance Health. Its purpose is to create a national care delivery platform that expands access to comprehensive primary care for consumers across Commercial, Individual Exchange, Medicare, and Medicaid health plans.

The platform's structure is a mosaic of distinct but complementary entities. It integrates:

• apree health: A digital navigation and clinical advocacy company that acts as a technology-driven front door for patients, helping them navigate the healthcare system and driving cost savings.
• Millennium Physician Group: A large, physician-led primary care organization with over 900 providers across several states, providing the foundational, community-based clinical infrastructure.
• CareMore Health: A physician-founded care delivery system known for its innovative, integrated model serving high-need seniors and other complex patient populations.

The central challenge and opportunity for Wenners will be to fully integrate these powerful but separate units. The goal is not to erase their individual brands but to enable them to exchange resources, data, and expertise to create a unified "whole-health approach." This involves deploying a community-based care model that is supercharged by the digital patient engagement, care coordination, and navigation capabilities drawn from across the platform.

The Push for a Personalized Patient Experience

A key mandate for the new CEO is to deepen the company's investment in digital innovation to make care more connected and personalized. This initiative builds on the inherent strengths of Mosaic's constituent parts. apree health provides the digital front-end, Millennium Physician Group is focused on creating a "connected healthcare experience," and CareMore Health uses advanced technology and data analytics to tailor care solutions for its members.

Wenners' background suggests a strong alignment with this vision. His leadership at Grouper, a platform focused on improving senior well-being through social connection, highlights an understanding of the social determinants of health—a critical component of holistic, personalized care. His work at Prospero demonstrates a commitment to bringing complex care directly to patients in their homes, a model heavily reliant on technology and coordinated logistics.

"I am deeply honored to lead Mosaic Health into our next chapter," said Doug Wenners. "Mosaic has built a strong foundation by bringing together care delivery and digital innovation in a way that can truly transform healthcare. I look forward to working with Clay and the entire team to expand access to high-quality care, strengthen our platform, and leverage digital technology to make that care more connected and personalized for every patient we serve."

Navigating a Competitive Value-Based Care Market

Mosaic Health's leadership change occurs within a fiercely competitive and rapidly consolidating value-based care market. The industry is dominated by giants like UnitedHealth Group's Optum and CVS Health's combination of Aetna, Signify Health, and Oak Street Health, all of which are aggressively vertically integrating to control costs and patient journeys.

Mosaic's structure as a PE-backed entity with a major insurer partner represents a different, though equally ambitious, approach to capturing value. By combining a large physician network, a specialized complex care provider, and a digital navigation tool, the company aims to build a flexible, multi-payer platform that can compete for patients across all insurance types. This contrasts with models that are more tightly bound to a single insurance company.

The appointment of Wenners, an executive who has operated at the highest levels of both integrated systems and nimble startups, is a clear strategic move to equip Mosaic for this contest. His proven ability to scale operations and forge effective payer-provider partnerships will be essential as Mosaic seeks to differentiate its model and prove its ability to deliver better outcomes at a lower cost. Under Wenners, Mosaic Health is now positioned to accelerate its integration, a move that will be closely watched by competitors and patients alike.
