Antón Castellanos Usigli, MPH, is a public health professional and consultant committed to global sexual and reproductive health and rights. Currently, he is the Assistant Director of Prevention Programs and Research at Wyckoff Heights Medical Center in Brooklyn, New York, overseeing an HIV/STIs testing program focused on young Hispanic men who have sex with men (MSM) and women, as well as a Pre-Exposure Prophylaxis (PrEP) program. At Wyckoff, he started an innovative online outreach strategy for MSM that has driven the increase of HIV/STIs testing numbers and PrEP enrollments. Antón’s work of HIV prevention in Brooklyn was recently featured by The Guardian and Vox.

As a consultant, he has worked for the Northern Manhattan Perinatal Partnership (NMPP), for RNW Media, the International Planned Parenthood Federation (IPPF) and the United Nations Population Fund (UNFPA). For IPPF he co-authored “Fulfil! Guidance Document for the Implementation of Young People’s Sexual Rights” (2016). In the past, he also worked for the Mexican Federation of Sexuality Education & Sexology in Mexico City and for the HIV Department of the Western Pacific Regional Office of the World Health Organization (WHO) in Manila, Philippines.

He is a Member of the Global Advisory Board (GAB) on Sexual Health and Wellbeing, a group of global experts brought together by Durex (the no. 1 sexual wellbeing brand in the world) to advance the links between sexual health, sexual rights and sexual pleasure across policies and programs. In this role, Antón co-developed a training toolkit for future sexual and reproductive health service providers on how to implement counseling that effectively links sexual health, sexual rights and sexual pleasure, as well as guidelines on inclusivity about sexual orientation and gender identity/expression for Durex.

Antón has a Master of Public Health from Columbia University in New York City and has been a speaker in Congresses across eleven countries.
