Become a Big Sister

Be Present, Not Perfect

Join the movement. Being a Big Sister is about developing a rewarding friendship with a girl based on having fun, learning, and growing together. Big Sisters are cheerleaders, champions, and confidantes who help girls develop the confidence they need to achieve their goals.

We are currently making Big and Little Sister matches virtually as a safety measure. All interviews, training, and visits with your Little Sister will take place online until we have determined that you can safely meet in person. As a Big Sister, you will be equipped with tools and support to help you engage with your Little Sister in a virtual environment.

Which Program Is Right for You?

Our Recruitment Specialists will help you decide the best fit for your lifestyle. 

Community-Based Mentoring

You will be matched in a one-to-one relationship with a Little Sister between the age of 7-15. Community-Based Mentoring Sisters typically meet on weekends and enjoy low- to no-cost activities that can range from baking to basketball, drawing to dancing, or science to sandcastle building. Big Sisters in this program must be at least 20 years old and commit to a minimum of 12 months with their Little Sister, meeting weekly for the first three months and twice per month after that.

Site-Based Mentoring

You will be matched  a one-to-one relationship with a Little Sister in elementary school in Boston or Cambridge. Site-Based Mentoring Sisters meet at the Little Sister’s school during her lunch period or at her after school program site. Together, they enjoy activities like crafts, reading, playing on the playground, or conducting fun science experiments. Big Sisters in this program must be at least 18 years old and commit to meeting with their Little Sister weekly for three academic semesters, excluding summer break and school holidays.

The possibilities are endless! During their time together, a match might visit a park, enjoy the beach, take walks, volunteer, explore different hobbies, learn a new skill, and so much more. Big Sister Association provides matches with free and low-cost activities (tickets to sporting events, movies, theater, museums) on a regular basis. Big Sister also hosts annual events such as the spring Appreciation Breakfast, Summer Picnic, Halloween Party, Teen Matches Give Back service projects, and Building Big Dreams career awareness events. No matter the activity, the most important thing is spending quality time together on a consistent basis.

First, don’t be afraid to acknowledge differences, either between you and your Little Sister or in the world around you. Take some time to think about your own feelings about differences, prejudices and stereotypes. It is important to pay attention to your own feelings, experiences and judgments because we all have them. Conversations with your Little Sister are an opportunity for learning and we encourage you to be open and sensitive about differences and values in all of your discussions. Please talk to your Match Support Specialist about any questions you might have regarding these discussions.
