Professional statement

*DISCLAIMER: Please do not request medication via Zocdoc. We will work with you on your medication needs after you establish your primary care with us. We are unable to refill any medications or respond to comments prior to your visit. Fluent in English, Spanish, and German, Dr. Gregory Hagan caters to the little ones of Cambridge, MA. He sees patients at CHA Windsor Street Care Center and is affable and reassuring during his consultations with kids and their parents. Dr. Hagan earned his degree in medicine from Tufts University and then went on to complete his residency in pediatrics at New England Medical Center. An experienced pediatrician, he holds certification from the American Board of Pediatrics. He is also an active member of the American Academy of Pediatrics. Dr. Hagan cares deeply that parents and their children learn about the challenges of growth, development, behavior, preventive health, and management of illness while receiving the treatment they need. His cheerful nature and a genuinely caring attitude make his patients feel at home. At CHA we believe that excellent health comes from a team of people working together, we call these care teams because it is their job to listen, respect and care for every patient at our clinic and in our community. A CHA doctor will lead a team - which may include physician assistants, nurse practitioners, registered nurses, medical assistants or other caregivers - who will get to know you well. Together, they will take responsibility for your health by offering consistent, coordinated care and communication. All returning patients should schedule within their existing care teams to ensure CHA is able to provide continuity of care.
