Clinical Leadership

The DaVita Patient-Focused Quality Pyramid, clinical initiatives—such as fluid and infection management—and other innovations that support clinical excellence were created and driven by these physician leaders, with group medical directors and physician partners, who have dedicated themselves to raising the standard of care for patients with kidney disease. They are shaping the future of kidney care by:

  • Developing a transformative vision of improved healthcare
  • Collaborating with a widespread physician community
  • Taking accountability for improving results
  • Addressing challenging clinical topics
  • Investing in physician development across all levels
  • Striving for a high level of physician satisfaction
