In 1990, he began working as an outreach educator for the Healthy Streets Outreach Program in Lynn, Massachusetts. In 1991 he accepted a position as Program Manager at Noddles Island Multi Service Agency working for the HIV Benefits Advocacy Program for persons who were HIV+. In 1997, he became the HIV Program Manager for CAB Health and Recovery Services HIV program in Lynn and is currently an independent consultant. Over his 13 years working at CAB, Langis helped to develop cutting-edge HIV prevention programs that encompassed principles of harm reduction and served as a model for other programs. In 1997, he was a founding member and Board President of the New England Prevention Alliance (NEPA), a group of activists that provide independent syringe exchange and Naloxone distribution to underserved communities. Langis collaborated with the state sharing data, forms, training methods and tools that were created and developed by NEPA that contributed to the foundation of the Opioid Overdose Education and Naloxone Distribution program. NEPA has conducted civil disobedience to highlight the disparities of HIV prevention in communities including Brockton, Lawrence, Worcester and Lynn.
