BMC’s Division of Adolescent Medicine is a medical home to adolescents and young adults ages 14 to 25. The division provides primary care and hosts subspecialty programs in areas such as addiction and substance use, family planning, gender care, menstrual disorders, and parent–child one-stop care for youth who are parents.
