What Harm Reduction Therapy Center does
Harm Reduction Therapy Center (HRTC) is a San Francisco-based nonprofit founded in 2000 by Patt Denning, PhD, and Jeannie Little, LCSW, that delivers integrated mental health and substance use treatment to unhoused and marginally housed populations through a harm reduction lens. The organization explicitly rejects abstinence-first prerequisites, providing therapy regardless of sobriety, engagement level, or insurance status. Its clinical delivery model spans four channels: street-based mobile therapy vans (operating weekly pop-up clinics in four San Francisco neighborhoods since 2018), a fixed drop-in center at 21 Merlin St. in SOMA (opened December 2022, serving ~30 people daily), a youth-specific program for homeless adolescents and young adults ages 18-24 (piloted in 2018 with the Homeless Youth Alliance), and traditional office-based therapy.
HRTC's technology stack is operationally focused rather than software-centric: converted therapy vans function as mobile offices, harm reduction kits (Narcan, fentanyl test strips, safer smoking/injection supplies) are distributed at field sites, and the organization maintains a website (harmreductiontherapy.org), Donorbox donation infrastructure, and standard social media presence (Facebook, LinkedIn, Twitter/X). Revenue is entirely grant- and donation-funded; all services are provided free of charge. Documented funding sources include MacKenzie Scott's Yield Giving (March 2024), SF Department of Public Health, Kaiser Permanente Community Benefits Program, and individual major donors. Beyond direct clinical service, HRTC operates a training and consultation business (1-4 day workshops, video curricula, monthly clinical supervision groups) and has authored the harm reduction therapy textbook 'Over the Influence' (Guilford Press).
In 2025 HRTC served 1,509 unduplicated clients with over 10,200 therapy contacts, supported by a clinical team of 11 full-time therapists plus additional recently hired staff. The organization maintains 20+ active partnerships spanning shelters (Episcopal Community Services, Covenant House, Hospitality House), public health agencies (DPH Street Medicine, SF AIDS Foundation, San Mateo County HIV Clinics), and youth-serving organizations (LYRIC, First Place for Youth, Gubbio Project). HRTC completed a five-year strategic plan in October 2024 and experienced a generational leadership transition in January 2022, when founders handed stewardship to a new team.
