Stony Brook Extended Care includes a primary care internal medicine practice and an OB/GYN practice. Our primary care practice provides preventative medicine and medical management of acute and chronic conditions to patients 18 and older. Our OB/GYN is devoted to the care of female patients whether it is for normal annual exams, prenatal care or medical problems. Most visits, consults, as well as tests and procedures, can be completed under one roof at our new office in Centereach.
