Planned leadership transition positions Mosaic to build on its mission of community centered care.
APPLETON, Wis., Jan. 22, 2026 – Mosaic Family Health has named Leif Elsmo as its new president following a planned leadership transition designed to ensure a continuity of care for patients across the Fox Valley. Elsmo will step into the role on Jan. 26, 2026. Mosaic Family Health is committed to providing comprehensive, mission-driven care to more than 6,000 patients in the Fox Valley.
“We are incredibly fortunate to welcome Leif Elsmo as Mosaic’s next president,” said Dr. Lee Vogel, president of Mosaic Family Health. “His talent and deep passion for community health will be tremendous assets to the Fox Valley. I look forward to working closely with Leif during this transition.”
Elsmo brings more than two decades of executive leadership experience in healthcare, academic medicine and nonprofit sectors. His background includes developing nationally recognized community health and health equity initiatives that integrate clinical care, public health and social services. His leadership style emphasizes collaboration and partnerships, aligning with Mosaic’s mission to deliver holistic, patient-centered care and its role as the clinical home of the Fox Valley Family Medicine Residency Program.
“I am honored to step into the role of president of Mosaic Family Health,” said Elsmo. “Throughout my career, I have seen firsthand how access to high quality, compassionate care can change lives, and Mosaic’s commitment to the Fox Valley reflects those same values. I am grateful for Dr. Vogel’s leadership and the strong foundation she has built, and I look forward to building on that work, expanding access to care, strengthening community partnerships and ensuring Mosaic continues to meet the needs of the patients we serve.”
“We sought a visionary, strategic and servant-minded leader with experience in the academic and non-profit sectors. Key priorities included a passion for patient-centered care, population health expertise, community relations experience, strong financial and analytical acumen and a proven ability to lead collaborative, multi-partner teams,” said Katie Ball, ThedaCare vice president of nursing excellence and clinical education and a Mosaic Board member.
“Following the significant growth and accomplishments achieved during Dr. Vogel’s tenure, including the opening of our new facility, the board is excited to expand Mosaic’s impact under Leif’s leadership,” said Mike Bergman, president of Ascension St. Elizabeth Hospital and Calumet Medical Center and a Mosaic Board member. “We look forward to advancing population health efforts and continuing to grow the Fox Valley Family Medicine Residency Program as one of the leading family medicine residencies available.”
Vogel will support the transition through Q1 2026, ensuring Mosaic’s tradition of quality care and strong community engagement continues uninterrupted. This leadership change reflects the organization’s long-term commitment to the Fox Valley, providing family-like, patient-centered care while building on its momentum and confidently preparing for the next chapter. Following the transition, Dr. Vogel will continue in a part-time role with Mosaic, supporting resident education in the Fox Valley Family Medicine Residency Program and caring for her personal panel of patients at Mosaic.
