Adam has nearly 20 years of experience in entrepreneurship and innovation in the private sector and in the U.S. Government. As the child of a primary care physician and a speech pathologist, Adam’s parents instilled in him the importance of caring, family, and community, and he saw how magic the time is between providers and their patients and the change that this can make in someone’s life.

Adam founded three healthcare companies including Landmark Health, a company delivering around-the-clock medical care to chronically ill patients. From there, Adam took on major roles in the U.S. Government, including Director of the Center for Medicare and Medicaid Innovation (CMMI), where he worked on value-based care for the United States. Adam was also a founding member of Operation Warp Speed, unanimously confirmed by the Senate as the first CEO of the International Development Finance Corporation (DFC), and a negotiator in the historic Abraham Accords.

After his government tenure, Adam started Rubicon because he wanted to build healthcare companies to transform how care is delivered in America, as he saw the power of bringing the private and public sector together to solve our nation’s greatest healthcare challenges.

Adam lives in Nashville with his wife, Shira, and their four children.

Dave has devoted his career to innovative businesses, including the last 15 years with companies transforming the way healthcare is delivered. He joined Rubicon Founders in 2024, and leads our Operating Partner team, helping our portfolio company leaders navigate the exciting stages of growth. Prior to Rubicon, Dave built and led the finance function at several investor-backed businesses, most notably as the CFO at Iora Health, a value based primary care provider that ultimately sold to One Medical (now part of Amazon).

He has seen and experienced firsthand the challenges of providing patient care in a world where financial incentives are misaligned with outcomes that matter to patients, and he believe there is an urgent need to fundamentally redesign the way health and healthcare is paid for, while simultaneously transforming the way healthcare is delivered.

Previously, David helped create value-based payment mechanisms at a large commercial payer, and he moved to Rubicon to help providers transform care delivery to succeed in value-based payment models and to be on the forefront of the transformation of specialty care in the United States. He maintains his practice and is also Assistant Professor of Urology at UNC Chapel Hill, with a clinical focus on urologic oncology.

David’s path to the healthcare industry started young by virtue of his family members in the industry. His mother was a nurse, and his father was a lawyer who served a large health system that primarily served Medicaid patients. Before that, his grandfather helped run and support a struggling children’s hospital in north Philadelphia for years – St. Christopher’s hospital for Children. This heritage of serving others in healthcare is what motivated his career in healthcare services. David joined Rubicon at the outset of the firm inspired by the vision of Adam Boehler to fundamentally reshaping how healthcare works.

David was born and raised just outside of Philadelphia, PA, and now lives in Washington DC with his wife, Sam, and their two daughters, Emily and Maddie.
