Millennium Physician Group and Lee Health announce strategic partnership

Southwest Florida’s senior population is growing, and navigating Medicare and chronic health conditions is becoming increasingly complex. To better support older adults in managing their health, Millennium Physician Group, a Mosaic Health Company and one of Florida’s largest physician-led primary care organizations, has entered into a strategic partnership with Lee Health. Together, the organizations will strengthen care coordination, expand preventive services and provide the tools and infrastructure needed to help seniors make informed decisions, manage chronic conditions and maintain greater independence.

This partnership is designed to support senior patients with complex health needs and will serve individuals enrolled in traditional Medicare and Medicare Advantage plans.

Both organizations will continue operating independently while collaborating to strengthen care for seniors in the region. As the partnership develops, patients will benefit from expanded care coordination and additional resources to support chronic conditions such as diabetes and heart disease, helping ensure they receive the right care at the right time.

“Millennium has built a strong, physician-led value-based care platform focused on improving outcomes while supporting clinicians,” said Kevin Spencer, national chief medical officer for Millennium Physician Group. “This partnership reflects a shared commitment to patient-centered care and allows us to extend our value-based care experience in a thoughtful, collaborative way.”

As part of the partnership, team members from both organizations will collaborate to support day-to-day operations related to Lee Health’s senior care efforts.

“This represents a meaningful step forward in how we work together to care for our community,” said Dr. Iahn Gonsenhauser, chief medical officer for Lee Health. “By aligning around shared accountability for quality, outcomes and cost, we are strengthening care coordination, improving the patient experience and building a more sustainable health care model that keeps patients first. Partnerships like this allow us to deliver better care for this community.”

Millennium Physician Group brings nearly 20 years of experience caring for Medicare patients through value-based care models focused on prevention, care coordination and long-term health outcomes. The organization’s approach has helped improve quality, reduce avoidable hospital visits and support sustainable health care delivery across Florida and beyond.

Lee Health is a trusted health care leader in Southwest Florida, serving the community for decades through a commitment to high-quality, patient-centered care, clinical excellence and community partnership. As a nonprofit health system deeply rooted in the region, Lee Health has long focused on improving access, strengthening local care delivery and advancing innovative models that meet the evolving needs of the community.

Together, Millennium Physician Group and Lee Health are combining experience, local leadership and shared purpose to strengthen senior health care in Southwest Florida, focused on improving outcomes, enhancing coordination and supporting the long-term health of the communities they serve.
