Girls In-Service
Girls In-Service Grades 11th and 12th Retreat April 2024

Girls In-Service is an amazing program for high school girls! With monthly workshops and service projects, your daughter is sure to grow!

Committing to 10 months of the program, girls meet for a kick-off retreat, one time per month for a Core Foundation meeting, and one time per month for a community service project. We have a lot of fun together as the girls grow close relationships despite coming from a variety of schools.

Core Foundation meetings are held the each month focusing on developing and utilizing the following Core Foundations of this program: Service, Purpose, Creativity, Leadership, and Wellness. Engaging in a variety of activities including craft projects, games, and group discussions, Girls In-Service members not only focus on the Foundations but also on receiving support from one another. Guest speakers also attend our meetings throughout the year to help our girls gain insight into careers, college, and how to live well.

Service projects typically happen on a Saturday or Sunday morning one time per month. We work with a vast amount of organizations to help girls gain insight into where they might find purpose and passion. Service mostly happens locally within Sonoma County. However, we also venture to projects in Marin County and San Francisco.

This year, the 9th and 10th grade cohort goes from October 2024-May2025. Girls commit to a full term of the program and do their best to show up to each Core Foundation meeting and service project.

Day Time Retreat: The Kick-Off Retreat to Girls In Service workshop takes place on Sunday September 21 from 9AM-3PM at Rusty Hinges Ranch. This initial workshop brings girls together towards their common mission of Service-Leadership-Creativity-Purpose-Wellness.

Core Foundation Meetings: Girls will focus on Service-Leadership-Creativity-Purpose-Wellness. Using guest speakers and a variety of activities, girls will develop solid skills around wellness to prepare themselves for life post high school. Not only will she develop life skills, but she will also be in connection with her peers for support and in knowing she isn’t alone as she navigates the teen experience. The Core Foundation meetings are something the girls really love to engage with as they love having time to talk and get a break from the school day. Core Foundation meetings are the 2nd Wednesday of every month from 6-7:30PM.

Monthly Service Projects- Girls will have the opportunity to help their community in a variety of ways to give girls experiences to contribute to something greater than themselves. Being in service builds confidence and esteem, and it will be a great resume builder for those going to college or heading out to the workforce post high school.

Why- Because all girls benefit from service, leadership, creativity, and finding purpose in their lives. In addition, she’ll build her resume for post high school endeavors.

Length of Program and Commitment- September 2025-May 2026 Girls are committing to signing up for the full term of the program upon registering. Ideally, girls will commit to the program for the duration of their high school years but it is not mandatory. This gives participants the opportunity to grow together in a meaningful way. Girls are committed to attending the 1 monthly workshop series and 1 volunteer experience each month. We understand that the Girls In-Service may conflict with other obligations, so we can be flexible in missing some events but ask girls to attend the majority of the events.

For example, during volleyball season, a participant may miss more workshops than usual but will get back to regular attendance once her season has ended.
