Meet our PrEP Navigators

Miranda Ramirez

Lead PrEP Navigator

“My name is Miranda Ramirez, and I am passionately dedicated to supporting the LGBTQ+ community in the fight for health equity. I believe everyone deserves access to safe, comprehensive healthcare, and I strive to be a voice for those who may not have one.

“Throughout my journey, I have actively participated in various initiatives aimed at promoting health and wellness, but my work with the Alexis Project at Friends Community Center in Los Angeles has been particularly impactful. In this role, I focused on connecting Trans patients with essential healthcare services, ensuring they received the support they needed. Despite the persistent discrimination and stigma that exist in society, I firmly believe that love, compassion, and understanding are our most powerful tools for fostering a brighter future where everyone can access the healthcare they deserve.”

Stefano Celsi

PrEP Navigator

“I was born and raised in Pescara, Italy; a beach town close to Rome.  After I finished college I moved to NYC and began a career in Fashion.  When I had the opportunity to move to Los Angeles and work in the healthcare system I took it right away. As a gay immigrant I was kept in good health, advocated for, and educated by an organization similar to Men’s Health Foundation.”

Sergio Velasquez is the Program Manager for Prevention Care Coordination (PrEP and PEP) at Men's Health Foundation, where he leads programs that strengthen access to HIV prevention services through thoughtful program design, operational excellence, and patient-centered care. His work focuses on building systems that make high-quality prevention services easier to access, easier to navigate, and intentionally designed to meet the needs of LGBTQ+, Black, Indigenous, people of color, and other historically underserved communities. 

Sergio's career has spanned HIV prevention, case management, clinical operations, and program leadership, giving him a broad understanding of how healthcare systems function from both the patient and provider perspectives. He began his work in HIV prevention while studying Human Biology at UC San Diego, where involvement with LGBTQ+ student organizations and the World AIDS Day planning committee inspired him to pursue a career in public health. Since then, he has led prevention programs, managed multidisciplinary teams, directed clinical operations, and developed workflows that improve access to PrEP, PEP, and sexual health services. Whether implementing new clinical processes, strengthening quality improvement efforts, or mentoring staff, Sergio is driven by a belief that good systems create better experiences for both patients and healthcare professionals.
