One year from the full implementation of federal health-insurance changes known as "Obamacare," the Petaluma Health Center in CA is gearing up for as many as 5,000 new patients in coming years. Last year the health center moved into a brand new 53,000-square-foot facility, recently hired five new healthcare providers, including two medical doctors, a psychologist and 2 physician assistants. The recent hires have "filled out" medical services currently being provided at the health center, said Kathie Powell, the health center's CEO.
