Hsieh has vast expertise and experience with Medicare and Medicaid products 





Worcester, Mass – Mass Advantage, the new Medicare Advantage health plan, has appointed Mary Hsieh as its Chief Executive Officer (CEO).  In this role Hsieh will launch and oversee all business strategies and operations.

“Mary’s success with provider-sponsored health plans and her experience launching and building new Medicare Advantage plans in Massachusetts and across the country made her a natural choice for Mass Advantage,” said Eric Dickson, MD, president and CEO of UMass Memorial Health and board member of Mass Advantage. “Her passion for improving the total healthcare experience for older adults aligned perfectly with our vision and commitment to this community.”

“Mary knows what it takes to build an organization that meets the needs of patients in the community,” said Jack Shields, Co-founder and Chairman of Shields Health Solutions and Board Member of Mass Advantage. “We are pleased to have her leadership as we build Mass Advantage to provide seniors in Central Massachusetts access to affordable, high-quality care that leverages the tremendous resources of UMass Memorial Health.”

Prior to launching Mass Advantage, Hsieh was the Managing Director of the Medicare Practice at Health Management Associates (HMA), a national consulting firm known for its expertise and thought leadership in state and federally funded programs, including Medicare and Medicaid. Under her leadership, HMA became the recognized premier firm in the $650 billion Medicare and duals market and expanded its Medicare advisory services nationally.

“I am honored to help build this historic new venture that will give Medicare-eligible patients here in Worcester County a more person-centered and dignified healthcare experience,” Hsieh said. “As a local plan, Mass Advantage will give its members access to UMass Memorial Health physicians and other providers in the area that they have grown to trust with their care. This organization will be laser-focused on its members and their needs.”

Hsieh has also served in various leadership roles at Kaiser Permanente, including driving the market strategy and performance for their government business lines in the Georgia region with over $750 million in annual revenues. She guided the company to become the first Medicare Advantage plan in the market to achieve CMS’s 5-star rating, the highest recognition for industry-leading performance in healthcare quality and customer satisfaction. She also established Kaiser’s Medicaid business in Georgia, creating access for 25,000 children in Medicaid to Kaiser’s acclaimed quality of care and services.

Hsieh holds a Doctor of Pharmacy degree (PharmD) from the University of California (UC), San Francisco, an MPH from UC Berkeley and a BS in Biochemistry from UC Davis.
