About Us

Our Mission

Girl Scouting builds girls of courage, confidence, and character, who make the world a better place.

Mid Peninsula Service Unit 389 supports and organizes activities for Girl Scout Troops in San Mateo and Foster City. In addition to this website, Service Unit wide updates are also communicated through our Google Group and private Facebook page. Feel free to contact us with questions or to request access to our private google group by email:  su389 @ scoutsnorcal.org (copy and remove spaces around @ )

About Girl Scouts

Girl Scouts bring their dreams to life and work together to build a better world. Girl Scouts of all backgrounds and abilities can be unapologetically themselves as they discover their strengths and rise to meet new challenges—whether they want to climb to the top of a tree or the top of their class, lace up their boots for a hike or advocate for climate justice, or make their first best friends. Backed by trusted adult volunteers, mentors, and millions of alums, Girl Scouts lead the way as they find their voices and make changes that affect the issues most important to them.

We’re the preeminent leadership development organization for girls. And with programs from coast to coast and across the globe, Girl Scouts offers every girl a chance to practice a lifetime of leadership, adventure, and success. 

Who We Are

We welcome any interested volunteers to participate in the Service Unit Team to help support and bring events and programs to our Scouts! We try to plan one event per month for Scouts to learn new skills, meet new friends, catch up with old friends and have fun.

Girl Scout Promise 

On my honor, I will try:

To serve God*

    and my country,

To help people at all times, 

    And to live by

    the Girl Scout Law.


* The word "God" can be interpreted in a number of ways. When reciting the Girl Scout Promise, it is OK to replace the word "God" with however one's own beliefs dictate

Girl Scout Law 

I will do my best to be

    honest and fair,

    friendly and helpful,

    considerate and caring, 

    courageous and strong, and

    responsible for

    what I say and do, 

 and to 

    respect myself and others, 

    respect authority,

    use resources wisely,

    make the world a better place, and 

    be a sister to every Girl Scout.
