OUr story 

Girls Supporting Girls was the product of a rant-session between co-founders Zoe Brown and Mariah Mercer. A discussion about the current teen culture sprouted into an organization. Committed to supporting and inspiring girls, GSG seeks to be a place of understanding, advice, and community. 


The GSG Team 


Zoe Brown 

Hi! My name is Zoë! I am a senior in high school and am a co-founder of GSG. I love to be busy and I am a social butterfly. I want to empower young women to fight society’s norms. I am going to college at University of Oregon where I will study political science in hopes to learn more about history and how to change it. I am so excited about this club and the amazing, uplifting activities we do!


Mariah Mercer 

Hey everyone! My name is Mariah and I am a co-founder of GSG. I am passionate about encouraging girls to dream big and chase their goals. I helped create GSG with the intent of cultivating a community that supports and lifts each other up. I love musicals, corn dogs and dancing in the kitchen. I hope you start your journey in GSG today, we are so excited to have you! 


Elizabeth Walker 

Hey! I’m Elizabeth and I will be a senior this coming school year. I love all things science and want to learn as much as I can. In my free time you can find me hanging out with my friends, watching Grey’s Anatomy, working at an embroidery shop, or reading.


Sarah Swingley

Hello everyone! My name is Sarah Swingley, and this fall I will begin my junior year at Carroll College pursuing a multidisciplinary degree in Public Health and Psychology. I have always had a heart for the little, the least, and the lost. I truly believe that every person I interact with has value and worth which deserves to be recognized and appreciated. I never want anyone to feel as though they are not respected and through my community engagement work my goal is to make sure that no one ever feels undervalued. In order to accomplish this goal, I have enjoyed participating in fantastic programs and research opportunities that have facilitated personal growth and experience as well as impacted the surrounding community.


Sidney Gates 

Hey Gals! My name is Sidney! I am a sophomore at Montana Tech and am embarking on my journey in the nursing program this fall. You will find me at my happiest during the summer when I can soak up as much sun as possible. I love to adventure and dive into learning more about health, kombucha anyone? My current goal is to not settle down but spend my time exploring as a traveling nurse, hopefully in the tropical areas of the world! :)


Christina Sieminski

Hey everyone!  My name is Christina Sieminski, I have been teaching science for the last 14 years at Capital High.  While I have loved teaching science, my favorite part of being an educator is helping students through the high school experience in a positive way by fostering a supportive and caring environment.  The part of my career that I am most proud of is the development of the Niceness is Priceless ® program in the Helena School District.  The program is an empathy building program that focuses on development through acts of kindness and aims to change the culture of our community by integrating emotional awareness and a network of mentorship K-12.  Girls Supporting Girls was created by the amazing girls that you see on this page, these girls have all been actively involved in Niceness is Priceless and developed GSG as a way of helping other students navigate their teen and young adult years.  I am so proud of everything that they have accomplished and am excited to see what the future holds for these five amazing young ladies!


ERin Heaton

My name is Erin and I am senior this year. I’m passionate about advocating for our youth, especially young women. I joined GSG to help foster a positive environment for Lady Bruins. High school can be a tumultuous, confusing time; We here at GSG want to create a community of girls who will support and uplift each other. You will meet amazing friends with different stories and experiences and learn life-long coping mechanisms. I especially aim to teach young girls to tools for dealing with adverse mental health and hope to diminish the stigma. 

Lili Keeton

Hey! My name is Lili and I’m a senior this year at Capital High! I was so excited to join GSG after the last virtual event. I am passionate about creating positive and constructive environments to live in, and GSG does just that. Apart from GSG I love to play soccer/tennis and hang with friends. Welcome to GSG!
