HMP Stigma

HMP Stigma (HMP) is an app-delivered intervention designed with and for young, Black and Latinx gay, bisexual and other men who have sex with men and transgender women. The intervention aims to improve HIV prevention and care by providing a platform where participants can find social support, build community, and engage with issues that matter to them. The app includes educational information on a range of health and lifestyle topics, delivered in a variety of formats (e.g. articles, quizzes, activities). HIV testing, prevention, and care resources are provided through an “Ask the Expert” feature hosted by a health navigator and board-certified infectious disease physician. The HMP approach strives to amplify resilience among participants by bringing diverse people together in dialogue as a critical step toward change.

Meet the HMP Youth Advisory Board

Tiffany Richardson

In 2017, Tiffany Richardson began her work within the LGBTQ+ community by serving as a member of the Rainbow Collaborative Project and the Patient-Centered Outcomes Research Institute (PCORI). These projects were centered on participatory research for and by LGBTQ+ youth and were facilitated by Dr. Mo from the Henry Ford Health System. Through this collaboration, Tiffany was able to learn the process of conducting effective research, and the importance of using ethical research practices and involve the community intended to be impacted.

Since then Tiffany has extended her reach within community, and has become a board member of Trans Sistas of Color Project (TSOCP). The TSOCP has given her the opportunity to connect with other trans women of color activists and organizers to improve and empower the lives of other trans women of color in the Metro Detroit area. In her spare time Tiffany enjoys movie nights with friends and community members, and I also an active member of the ballroom scene; a series of categories in which members of respective houses compete display various talents to win titles, trophies, and cash prizes.

Elias Preciado

I am a second-year MPH student at Columbia. I study epidemiology and health policy. I got my B.S. in Public Health at Syracuse University. I am originally from San Diego. After grad school, I’d like to focus on HIV-prevention and increasing access to PrEP for high-risk communities. Aside from working in public health; my life long goal is to be on Survivor! So hopefully you’ll see me running around on an island someday!

Sloane Allen

My name is Sloane and I am 21 years old. I identify as trans fem and love to volunteer with organizations such as, Gay for Good, and recently Equality NC. One subject I am extremely passionate about, is the equality and education about Trans and Gender Non-Conforming people of color. Pursing a degree in Mass Communications (journalism), I hope to one day be able to shine a light on the often forgotten or mistreated community of Trans and Gender Non-conforming people.
