Under this new agreement, their coverage will expand to include coverage at St. Helena Hospital 24/7.

In today’s announcement, Terry Newmyer, President and CEO of Adventist Health Northern California Network, expressed great enthusiasm and excitement. “Expanded orthopedic coverage with these highly skilled surgeons means patients can have expert orthopedic care right here at St. Helena Hospital,” says Newmyer.
