Please email for questions about setting up your new user ID/password.

Our caregivers have extensive experience caring for families, from pediatrics to geriatrics, and everyone in between – health care you and your family can trust.

Open Access Scheduling™, which means appointments are made on the day and time that works best for the patient, with same day and next day appointments are available as well. We also offer continuity of care, by coordinating your care at the hospital, in the event that you are ever admitted. 

Community Medical Associates (CMA) is affiliated with Lawrence General Hospital, so our patients now have access to specialists from Boston, including Floating Hospital for Children at Tufts Medical Center. Together, we provide you and your family with the expert care you deserve.
