The Practice

The HLS practice mission is to “transform healthcare through the relentless pursuit of a better way.” The team works with C-suite and senior executives and management teams in the Health Insurance, Health Services, Retail Health, Pharmaceuticals, Biotechnology, Healthcare Provider, Health IT, Pharmaceuticals, Biotechnology, and Medical Devices Industry on wide ranging issues of strategic impact.
