BMC’s Yawkey building doors are now closed as an entrance as part of our ongoing efforts to enhance our campus and provide you with the best clinical care.

All patients and visitors on our main campus must enter our hospital via Shapiro, Menino, or Moakley buildings, where they will be greeted by team members at a new centralized check-in desk before continuing to the hospital. We are excited to welcome you and appreciate your patience as we improve our facilities.

At Boston Medical Center, the Center for Addiction Treatment for AdoLescent/Young adults who use SubsTances (CATALYST) program helps teens and young adults who use alcohol or drugs. Our team provides access to a wide range of services including primary care, harm reduction, assessment and treatment of substance use disorders, psychiatry, psychotherapy, and recovery support for patients through age 25 and their families.
