At North Suffolk Cardiology, our APPs include nurse practitioners (NPs) and physician assistants (PAs). These dedicated professionals have completed advanced education and training in cardiology, allowing them to assess, diagnose, and treat a wide range of cardiovascular conditions under the supervision of our cardiologists.
