Sonia Millsom is the CEO of Oxeon, a trusted healthcare firm, powering change through talent, entrepreneurship and investment. She is a veteran healthcare leader who has been at the forefront of value-based healthcare, with extensive experience growing mission-driven innovative companies, as well as serving as an adviser, board member and investor.
Sonia is a dynamic healthcare executive who is known for her sharp insights and for her ability to see around corners, forecast consumer trends and drive remarkable growth. Her vast, multifaceted network of relationships spans virtually every healthcare industry segment, from startups to the biggest publicly traded corporations, and across the full spectrum of purchasers, payers and providers. She has worked across the healthcare ecosystem building solutions to deliver better care for commercial, Medicare and Medicaid populations, and has worked with founders and early-stage boards to evolve initial business models into scalable, sustainable growth strategies and paths to exit. She has successfully identified market trends, executed multiyear growth plans, expanded new lines of business, and delivered revenue growth for large national payers, mid-size tech-enabled services companies, and startups.
Prior to joining Oxeon, Millsom served as the Chief Commercial Officer at Maven Clinic, a telemedicine-based virtual clinic for women and families, which achieved the first unicorn valuation in women and family health. Before joining Maven, she was Chief Growth Officer at Boston-based startup Iora Health, where she helped strengthen the organization’s revenue and oversaw an expansion that led to its $2.1 billion acquisition by One Medical. Sonia also held leadership roles at Best Doctors, Health Dialog and UnitedHealthcare.
Improving healthcare has been a personal mission for Sonia since her time as a Maternal and Child Health Peace Corps volunteer in Morocco — where, in the 1990s, she witnessed close-up how broken delivery systems lead to poor care. She is a professional mentor to budding healthcare leaders with Menttium. She also is a board member and serves on the Audit and Compliance Committee for Clever Care Health Plan — which was founded to provide culturally sensitive health solutions for seniors. In addition, she is a board member for the Social Enterprise Greenhouse, where she chairs the Board Nominating and Development Committee, and for HealthSource RI, Rhode Island’s Affordable Care Act insurance marketplace. She holds advisory board member positions at Stellar Health, QHLTH and Flourish Fund.
Sonia has a Master of Public Health degree from Columbia University and a Bachelor of Arts from Boston College. She resides in East Greenwich, Rhode Island, where she and her partner are raising the next generation of strong women as the parents of two daughters.
