Brandyn River Gallagher, a devoted activist and community servant, is committed to Justice and the equitable redistribution of happiness. His strong voice in addressing the limitations of sexual health resources for transmasculine people has resulted in significant improvements to HIV research methods and study design internationally.

Brandyn is passionately dedicated to building community, bridging interpersonal divides across the chasms of structural inequity, and healing wounds in the wake of the HIV epidemic.

For two years, Brandyn served as leader of the WHO-recognized PrEP Facts: Rethinking HIV Prevention and Sex, and he formed the Trans MSM: Rethinking Sexuality and Health educational support group. He loves engaging with researchers heart-to-heart addressing the importance of trans inclusion in medical science and is pursuing a Masters of Public Health to effect more sustainable, community-rooted changes to our healthcare.

Brandyn is available professionally for writing, group presentations, trainings, and independent consulting on topics of trans-competency in sexual healthcare tailored to the needs of your organization or project. For more information or booking, please send a detailed email to or use the contact request form.

Brandyn is one of our country’s hottest young health advocates to keep both eyes on. Equal parts passion, smarts, and tenacity, his work on behalf of transgender men, HIV prevention, and PrEP is thrilling to watch as it unfolds. He is how positive change happens. Queers of all flavors and varieties, and especially trans men, already have a lot to thank him for – whether they know it or not. I am privileged to be his ally and comrade.

Brandyn’s exceptional ability to analyze, synthesize, and convey novel information through a unique and relevant lens consistently impresses me. Multi-faceted and versatile, there are no bounds to the work he’ll do in the interest of community building – be it handing out condoms and talking with homeless teens about safer sex, critically examining and identifying shortcomings of major medical research, or compassionately and effectively communicating those shortcomings directly to the world’s leading scientists to improve methodological accuracy and accountability. Brandyn is a natural leader with insatiable curiosity and endless passion, whose contributions to the field of sexual health have been immeasurably impactful and enlightening. It is inspiring to witness his activism in action.

Brandyn has something I recognise from the young gay activists I used to hang out with back in the late 70s: fearlessness, intelligence, impatience – but impatience with added smarts and political savvy. He’s part of a new, yet not so new voice in sexual politics: a post-AIDS generation who are challenging perceived notions of gender, role and lifestyle in the way Gay Lib did in my youth and which I feel the AIDS tragedy derailed. I’m proud to have been part of a movement young activists like him are taking over and transforming. He’s engaged, bold, sexy, sharp and tells you what’s what. I like that.

When it comes to standing up for the rights of transgender men to access responsible and informed healthcare, Brandyn Gallagher is unparalleled. His intelligent, creative, and humane approach to communication is making a formative difference in the world of HIV prevention, PrEP education, and research. In my two decades of work, I have never seen someone discuss the health disparities of transgender individuals with such detailed clarity, remarkable persistence, and admirable resilience. I am honored to moderate the “PrEP Facts” group page with him, and look forward to his contributions for years to come.
