Fenix Staff

We share a committment to compassionate, culturally sensitive care for our Latino neighbors, in their native language, Spanish!

Meet the people who make the clinic.

They are the heart and soul of Fenix Family Healthcare. Most of the people who spend their professional lives working at Fenix have been immigrants themselves and are fully aware of the challenges facing our patients as they begin to integrate into the culture of their new home.
