During his tenure, Bernard has focused on public health and preventive care, rather than just treating disease, seeking to provide high-quality, affordable, accessible health care to all of its members. And from his position of considerable influence, he has brought an often overlooked aspect of medicine to the forefront: mental and emotional health.

Because of Bernard's leadership, Kaiser's 200,000 employees and 20,000 physicians have consistently delivered some of the best clinical outcomes in the nation.
