We've all heard the saying, "you can't be what you can't see." This sentiment reflects the importance that trailblazers, role models and mentors play in our lives. They show us what's possible, they set the bar of achievement and they encourage us, even challenge us, to leap over it. It is vital that girls who aspire to become leaders in our world have access to women who have already attained leadership positions — it makes the idea of women leaders real, something they can see with their own eyes and believe is possible to achieve. Above all, it gives them a goal to reach for.

That is why Girl Scouts of the USA established Troop Capitol Hill, an honorary Congressional Girl Scout Troop made up of all female members of the United States Congress. Troop Capitol Hill gives Girl Scouts everywhere a sense of being directly connected to their leaders in Congress, and each troop member serves as a role model for girls across America. By participating in initiatives like our Portraits in Leadership series of interviews, Troop Capitol Hill members make themselves available to girls, offering them the guidance and support they need to move ahead in the world.

The importance of role models for girls cannot be overstated. Read Girls Scouts USA CEO Anna Maria Chavez's complete Huffington Post blog to find out why.
