Sara Holtz

Sara has nearly 20 years of experience in global public health including Peace Corps/Togo, USAID/Senegal, USAID/West Africa, World Bank, university research centers, and USAID-funded projects. She currently works for the CIRCLE Project focused on using evidence-based approaches to improve maternal, newborn, and child health in low- and middle-income countries. She has a bachelor’s degree in international relations and French from William and Mary, a master’s degree in public health from University of North Carolina, and a doctor of public health degree from Johns Hopkins Bloomberg School of Public Health.

In her spare time Sara enjoys volunteering and mobilizing groups of volunteers, particularly youth, to participate in community service projects. For the past ten years she has volunteered for the Girl Scouts Council of the Nation’s Capital to bring STEM, Leave No Trace outdoor ethics, and global programs to Girl Scouts in the DC metro area. With the local BSA council she teaches Leave No Trace and advises scouts on significant conservation and environmental projects. At the local elementary school she’s the parent member of the STAMP (Science Technology Art Music Philanthropy) committee aimed at providing family-friendly STEM and volunteer opportunities to the school community. In Fairfax County she serves as a site leader for the Fairfax County Park Authority Invasive Management Area program to educate the public and lead work days to remove invasive plants from public land, helps label storm drains with the Soil & Water Conservation District, and plants native trees with Fairfax ReLeaf.

Christa Weber

Christa Weber is a 5th grade teacher at Crestwood Elementary School in Springfield, Virginia and has been working with RESET volunteers for the past six years. Prior to becoming a teacher, she spent two years as a Peace Corps volunteer in Vanuatu, inspiring her to switch careers to teaching. Ms. Weber acquired her teaching credentials from California State University, Monterey Bay and volunteered with AmeriCorps through Girls Incorporated.

Ms. Weber holds endorsements in Advanced Academics and STEAM through Fairfax County Public Schools. These endorsements have empowered her to provide rigorous opportunities to students who might not otherwise have access to them. Ms. Weber’s passion for science was ignited when she was selected to attend a pre-service teacher training institution hosted by the National Institute of Aerospace (NIA) and NASA Langley. Being immersed in science for two weeks was all it took to hook her. This experience empowered her to become a strong science educator that has led to many leadership opportunities in and outside of her school.

Ms. Weber believes that in order to help children reach their fullest potential, they must be provided opportunities to apply STEAM knowledge to real life scenarios and see themselves in roles they aspire to become.
