Meet our team 

Kate Silverman

 Executive Director

Kate was an avid soccer player while growing up in Montclair, New Jersey. She played defense for the local travel, high school and club teams and also ran track for her high school. Upon graduating in 2005, she went on to attend Amherst College. There she ran and captained both Indoor and Outdoor Track and played club soccer, while majoring in Psychology and Sociology. She led trips for high school students through Overland Summer Camps in 2008 and 2009 and then joined the full-time Overland team for the five years following graduation - most recently serving as Director of Enrollment and Operations. During her time there, she coached community youth soccer and track teams, and regularly played in the town's vibrant pick-up soccer scene. 


Before joining Woza full-time in 2015, Kate spent a year working and volunteering abroad in New Zealand, Australia, Africa and South America. Now based in Seattle, Wash., Woza perfectly combines her experience in the student travel industry with her passions of traveling, working with youth, and, of course, playing soccer.

Born and raised in Oakland, Calif., Arielle played soccer all her life and attributes much of her growth as a human to soccer. Arielle graduated from Carleton College in Northfield, Minn., in 2014 where she played four years of Varsity soccer, winning two league championships and making an NCAA appearance. She also played three years of Ultimate Frisbee and served as a member of the leadership body. While in college, Arielle took full advantage of the study abroad experience, traveling to Ethiopia and Australia. In the summers, Arielle led wilderness trips for Overland Summers, hiking all around the world with fun-loving teenagers. Since Carleton, Arielle has taught high school science and wilderness leadership at the High Mountain Institute, and led a college study abroad program in Australia with Carleton, her alma mater.


Arielle has led two Woza's South Africa programs: South Africa Zululand in 2016 and South Africa Leadership Course in 2017. In between summers, she helps Woza with outreach and student-alumni relations. She is ecstatic to combine her love of soccer, with her passion for travel, and her excitement for working with young people all in one place

Sam Gest

Outreach and Programming Manager

Originally from Norwich, Vermont, Sam grew up participating in all kinds of sports throughout the year, and played soccer all the way through high school. Upon graduating in 2010, Sam attended Ithaca College in upstate New York, where he studied Journalism and Sport Studies. Prior to joining Woza, Sam spent a year working for Grassroot Soccer in Cape Town, South Africa. As someone who lived abroad working for a Sport for Development organization, Sam has seen firsthand the power of soccer to positively change lives, bring people together and empower those involved, especially women and young girls. Sam has a passion for sustainable development, and hopes Woza trips and a glimpse at the Sport for Development world will have a similar impact on Woza participants.

Sam's past work experience includes the United States Olympic Committee and USA Table Tennis, both in Colorado Springs, Colorado. Upon moving to Colorado, Sam helped found an adult soccer club in 2014, which has grown to over 70 players as of June, 2017.
