About Us


Big Brothers Big Sisters is a not-for-profit foundation established in New York City in 1904. Since then, it has provided more than 3 million children with professionally supported one-to-one mentoring relationships. Currently, there are over 250,000 active matches in the US and over 30,000 matches internationally.

It all started in 1904, when Ernest Coulter, a young clerk in the New York City Juvenile Court saw increasing numbers of boys come through his courtroom. He recognized that caring adults could help many of these kids stay out of trouble, and he set out to find volunteers. That marked the beginning of the Big Brothers movement.

At around the same time, the members of a group called Ladies of Charity were befriending girls who had come through the New York Children’s Juvenile Court. That group would later become Big Sisters.

Both groups continued to work independently and eventually merged. More than 100 years later, Big Brothers Big Sisters remains true to our founders’ vision of bringing caring role models into the lives of children. And, today, Big Brothers Big Sisters currently operates in all 50 states in the United States and in 12 countries around the world.

Big Brothers Big Sisters of Poland was established in 2014. Big Brothers Big Sisters of Poland is fully funded and requires no funding from its stakeholders or the community.
