We are across the street from the main entrance of Boston Children's Hospital, in the same building as the Bank of America. The Boston HAPPENS program is located in the Adolescent Clinic, fifth floor.

How to get here

  • By MBTA train: Take the Green Line to the Longwood stop on either the “D” (Riverside) or “E” (Heath Street) train. Once you are on Longwood Avenue, walk down the street into the Longwood Medical campus, about a five to 10 minute walk from either train line. Our office is located at 333 Longwood Ave., a red brick building with a Bank of America out front. The entrance to our building is through a pair of glass doors. Take the elevator to the fifth floor. The Adolescent Clinic is on your right.
  • By MBTA bus: From Ruggles Station, take the CT2, 8, 19, or 47 bus to the Longwood Medical Area. Get off at Boston Children's Hospital. The 333 Longwood building, a red brick building, is across the street. Take the elevator to the fifth floor. The Adolescent Clinic is on your right.
  • By car: Parking is in the Boston Children’s Hospital Patient and Family Garage on the corner of Longwood Avenue and Blackfan Street (the entrance is on Blackfan Street). This is the only parking garage we can validate tickets for; all other area garages are private garages and can be rather expensive. When you come out of the parking garage, cross Blackfan Street and walk up Longwood Avenue towards Brookline Avenue. 333 Longwood is the second building on the right hand side; it is a red brick building with a Bank of America on the ground floor. Take the elevator up to the 5th floor. The Adolescent Clinic is on your right.
