Sarah is a Youth-Centered Health Designer at YTH. She contributes to a variety of YTH programs related to community health and sexual and reproductive health, such as INSPIRE+, a human-centered design accelerator for youth-led projects, and PrEPTECH, an integrated tech approach to increasing pre-exposure prophylaxis (PrEP) uptake among young gay and bisexual men. Sarah brings a background in health equity and human-centered design, communications and storytelling skills, and experience in rigorous quantitative and qualitative analyses. She is a first-generation Korean immigrant who is passionate about how technology and innovation can be leveraged to move the needle on entrenched or overlooked sexual and reproductive health, such as contraception access and menstruation.

Prior to working at YTH, Sarah graduated from University of California, Berkeley with her Masters in Public Health with a concentration in Maternal, Child, and Adolescent Health (MCAH). Her capstone research examined how pesticide exposure impacted adolescent menstrual cycle characteristics and timing of menarche in a community of Latino farmworkers in the Salinas Valley. Sarah also worked at Berkeley Media Studies Group (BMSG), where she studied how public health issues appear in the media to push the needle on topics like sexual violence prevention, child welfare, immigration, and housing, sharpening her background in advocacy, training and facilitation skills, and her capacity for storytelling and communications. Before her time at BMSG, she conducted impact evaluation, research, and strategic planning for nonprofit, public, and philanthropic organizations across the US at Learning for Action, a social sector consulting group. She graduated with her BA in Human Biology, with a minor in Media Studies at Scripps College for Women in Claremont, California.

Caryn Graves has been working for YTH since 2005, performing the “nitty gritty” technical implementations that bring to fruition the end products out of initial concepts.

She has worked on numerous projects over the course of her years at YTH, such as websites for health clinics, STD partner notification, clinic locators, SMS reminders, online faxing of prescriptions, and social media campaigns. YTH has been an ideal outlet for her desire to apply the latest technologies in innovative ways for good social causes.

Caryn has a Bachelor of Science in aerospace engineering from USC and Master of Engineering in mechanical engineering from the University of California, Berkeley. Before joining YTH, she worked as a software engineer in the private sector.

When not helping to forge the frontiers of sexual health promotion, Caryn undertakes a challenge very different in nature but no less in magnitude—the parenting of her two school-aged children. She also enjoys science fiction, games, running, gardening, cooking, and a wide range of music.
