Antón Castellanos Usigli, MPH, is a public health leader with more of a decade-long career in population health and sexual and reproductive health for communities that face inequities in social determinants of health. He is a Doctor of Public Health (DrPH) candidate at the Harvard T.H. Chan School of Public Health. Antón is a Consultant at the executive level of AIDS Healthcare Foundation (AHF), where he is conducting strategic planning on coordinated care systems to strengthen patient retention, re-engagement, and experience. He is also a Consultant for Fenway Health in Boston, MA, focused on increasing the volume of clients through digital marketing strategies, Pre-Exposure Prophylaxis (PrEP) uptake, and strengthening patient experience. Antón served as the Director of HIV/STI Prevention of Wyckoff Heights Medical Center in Brooklyn, NY, where he was instrumental in designing and developing sexual health programs that deliver services such as HIV/STI testing, STI treatment, PrEP, and linkage to HIV medical care to hundreds of clients every year. In 2016, he started an innovative online outreach strategy to link men who have sex with men (MSM) to comprehensive sexual health services through dating apps. To date, this strategy has successfully brought more than 300 new clients at Wyckoff for HIV/STI prevention services and became a best practice that other NYC-based agencies have replicated. Antón’s work on HIV prevention in Brooklyn has been featured by NBC News, The Guardian, and Vox. Antón is a Member of the Global Advisory Board (GAB) for Sexual Health and Wellbeing, a group of SRH experts brought together by Durex, the leading sexual wellbeing brand in the world, who have pioneered in the development of the “triangle approach” linking sexual health, sexual rights and sexual pleasure with implications for public health programs and policies worldwide. In this role, Antón co-developed a training toolkit for future health care providers on how to implement quality SRH services based on the GAB’s triangle approach, as well as guidelines on inclusivity about sexual orientation and gender identity/expression for Durex. He is also a Member of the National Board of Directors of PFLAG. Antón has a Master of Public Health from Columbia University in New York City, a Bachelor of Science in Psychology from Universidad Iberoamericana in Mexico City, and has been a speaker in Congresses across twelve countries.
