Patient-Centered Care

Catholic Health's Independent Physician Association (IPA) physicians seek to heal our patients first and foremost. We are transforming local health care and revolutionizing the very concept of quality health care.

We are a collaboration of employed and independent primary and specialty care physicians from across Long Island. We are dedicated to achieving a system of high-quality, coordinated health care that supports physicians and reduces unnecessary costs while providing clear-cut benefits to patients. Better population outcomes are achieved through a transition from disease-driven care to a focus on prevention and wellness.
