How It Works

  1. Fill out the online application, use our online scheduling tool, or call us at 617.236.8077.
  2. One of our Recruitment Specialists will contact you by phone to process your application.
  3. Once your application is processed, you will be scheduled to interview with an Enrollment & Matching Specialist that will take place in the convenience of your home or at our office, if you prefer. During the interview, our Enrollment and Matching Specialist will meet with the caregiver and the potential Little Sister to learn about her. This will enable us to choose a Big Sister who is the best fit for her personality, interests and needs.
  4. Once we select a Big Sister for the Little Sister, we will inform the caregiver about that Big Sister, so that we can make a final decision about the match. The initial meeting will take place in the Little Sister's home. After the initial meeting at the Little Sister's home, the match can embark on their newfound friendship.
