She also spearheaded the development of the overall market program strategy and led the team’s successful efforts to secure an award under the Michigan Comprehensive Health Care Program Medicaid RFP bid. Additionally, Musser has been instrumental in developing a 2025 Marketplace launch plan for Michigan.

"Sarah has been a driving force behind our success in Michigan, leading the implementation of key programs and shaping our overall market strategy,” said Steve Smitherman, CareSource regional vice president, Midwest region. "Her leadership and strategic vision have been crucial in driving growth and expansion, and we look forward to her continued contributions as we strengthen our presence across the state.”
