Model & Strategy

Y2Y’s vision is to create a network of communities where all young adults experiencing homelessness have a safe place to rest, grow and lead. Y2Y Harvard Square is a student-run overnight shelter, quickly getting young adults experiencing homelessness off the street to prevent trauma.

Y2Y guests are given the space and support during their 30-day stay to identify concrete pathways out of homelessness, and take steps along that path.  They have opportunities to collaborate with service providers, other young adults experiencing homelessness, and student volunteers to create sustainable pathways out of homelessness and develop skills for long-term success.

Meet Sam Greenberg and Sarah Rosenkrantz

Sam and Sarah met while students working at the Harvard Square Homeless Shelter (HSHS), where they served on staff. Before college, each had developed a passion for issues of housing and homelessness.  At Y2Y, Sam and Sarah have built a wide, diverse and passionate community of supporters, including key political figures from Boston and Cambridge and a wide volunteer base. They graduated in May 2014 from Harvard and were recently part of the 2015 Bostonians of the Year Honorable Mentions list by the Boston Globe Magazine.  In 2017, they were part of the Forbes 30 under 30 Social Entrepreneur class.


Y2Y’s vision is to create a network of communities where all young adults experiencing homelessness have a safe place to rest, grow, and lead. Last season, 76% of guests report feeling safe during their stay, 83% of guests would recommend to a friend, 91% of guests feel more connected to their peers after their stay, and 69% of guests report leaving Y2Y with a concrete plan for their pathway out of homelessness.

Y2Y has served over 200 young adults experiencing homelessness at Y2Y Harvard Square in Cambridge, MA.

Y2Y raised over $1 million in a capital campaign to open its first shelter in Harvard Square in 2015. They are currently supporting a group of Yale students in working to open Y2Y New Haven.
