About Us

All Inclusive Primary Care, in collaboration with Stony Brook Medicine, is a primary care practice providing preventive medicine and medical management of acute and chronic conditions to patients 18 years and older. Our staff will facilitate patient-centered care through community resources, medical referrals and patient families.  In our primary care setting, we are committed to using evidence-based medicine to help provide quality care that has its foundation in shared decision making with our patients and their families.

We are a Patient-Centered Medical Home (PCMH) provider in which the model of care puts patients at the forefront of care. The goal of the PCMH model is to provide safe, high-quality, affordable and accessible patient-centered care by promoting stronger relationships with patients, addressing care needs more comprehensively and giving time to coordinate care across all sectors of the healthcare system.
