What Health Through Walls Inc does
Mission
HtW was created to assists prisons in resource poor countries test treat and implement measures to control and stop the spread of contagious diseases such as HIV/AIDS, other STI's, TB, Cholera, COVID-19 and other emerging infectious diseases and also to implement programs to eradicate malnutrition and provide skills training to prisoners. HtW focus is on key population affected family members and sex partners and the communities in which they live. At inception HtW was the only NGO dedicated to the care of the prison population. HtW also operates an outpatient clinic providing medical services to the poor and to released prisoners family members and sex contacts.
As stated on its FY2024 Form 990.
Programs
On its FY2025 return the organization reported starting a significant new program and a significant change in how it conducts a program.
USAID was Haiti's largest donor, providing 65% of all humanitarian funding in 2024. The January 2025 executive order from the Trump administration suspended virtually all U.S foreign aid, halting 80% of American funded programs in Haiti, including the HAPH program administered by Health through Walls. Stop-work orders were issued within days, and most USAID staff were placed on administrative leave by February of that year. This meant that programs didn't just lose funding, they lost the personnel and administrative machinery required to operate.
Its own explanation, from Schedule O of that return (Part III, line 2).
The HAP program, funded by USAID was terminated because the funding agency was closed by the government. HIV/AIDS Assistance for Prisons in Haiti objective is the control and prevention of the spread of contagious diseases in Haiti's 17 prisons. Haiti's prisons do not have a sustainable system of care and HtW through funders help to fill in many gaps that exists to prevent neglect of care of the upwards of ten thousand inmates incarcerated there and eventual death of those who are sick or who contract a deadly disease while incarcerated. HtW had over 130 full time staff including doctors, nurses, laboratory technicians, counselors, radiographers and psychiatrists who work at all locations throughout the country, in the East, North, West and South. HtW is charged with setting up a sustainable system of care providing sanitation for all the prisons and creating a clean working environment for the officers and health care workers and a healthy living environment for the prisoners. HtW implemented a WASH program to ensure clean water for drinking, cooking and showering. This program saved thousands of lives and help treat many people infected by contagious diseases and provided HIV medication to thousands of people living with HIV.

These funds allow us to increase and improve prevention, screening and testing of HIV/AIDS and TB in 5 additional prisons in Haiti. These prisons are located outside of the metropolitan area. We also provide care and treatment services for all prisoners indentified as TB+ and HIV+. This program allows us to screen for MDRTB and negotiate and set up isolation areas for those identified. HtW is charged with renovation of prison medical offices and replacing destroyed equipment, development of a hospital ward at the PCPP-M, recruiting and training medical staff for facilities without staff, training Health Promoters and a peer education program in all the prisons.

This free program will provide virtual training programs to both correctional clinicians and provide peer education programming to incarcerated persons with the objective to reduce new HIV infections and the eventual end to the HIV epidemic. Prisons in resource poor countries face many challenges in delivering adequate health services. The prisons often have extreme conditions of overcrowding, lack of sanitation, safety hazards, poor nutrition, and little access to health professionals. These are often the same countries with the highest prevalence of HIV infection. The ramifications of failing to identify or prevent or properly manage HIV infections pose a threat to the entire prison population, staff, visitors, and community. Incarcerated persons are a key population often missed by traditional HIV programs.…

This project aims to deliver an integrated model of care that includes the strengthening of TB and HIV identification and treatment and screening and treatment of other illness in two Bangui prisons, namely Ngaragba and Bimbo prisons. Services will be delivered by Amici per il Centrafrica (Amici) and Health through Walls (HtW) in conjunction with the existing health and prison administration within the Central African Republic prisons and national strategic plans for health in prisons. One of the aims of this integrated partnership is to build capacity. The newly commissioned services will be integrated within the health program and include the identification, treatment, health promotion/education, and community referral (when discharge from prison occurs) for TB, HIV, malnutrition, fungal disease, skin conditions, hypertension, diabetes, chronic respiratory disease, cardiovascular diseases, and mental illness. To enhance the TB program, digital interventions are proposed. These include annual digital chest x-ray screenings, artificial intelligence (AI) for rapid x-ray interpretation, and implementation of an electronic patient management…

To bridge this gap and lay the ground for a more robust response to HIV, TB and Malaria, complementary interventions are urgently needed especially in 6 prisons not covered by current Health Programs. Our intervention will be mainly concentrated among detainees, released prisoners, and their families who form the most vulnerable and most at-risk population groups as a continuum linkage of care from the prisons to the community to address the Gap in Tuberculosis, Malaria, and HIV in a patient centered gender approach. Our overarching goal is to establish an integrated healthcare program aimed at enhancing access to comprehensive TB, HIV, and malaria care within Haiti's prison system while extending these vital services to the communities, and family members of incarcerated individuals. The project seeks to bridge the healthcare gap by ensuring equitable access to quality medical services and education and reducing the prevalence and impact of these diseases among incarcerated persons and the community. Our direct beneficiaries will be the incarcerated persons in a primary place, and correctional agents in…

The organization over time
Each line starts at 100 in 2020, so what you read is the shape rather than the size: 150 means half as much again as 2020, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2021 to 2022, from $3.7M to $5.7M (+55%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2020 81% · 2021 73% · 2022 64% · 2023 58% · 2024 79%. Grants only. Government contracts and fees sit inside program revenue.
100% of HEALTH THROUGH WALLS INC’s revenue is contributions — more reliant on donations than three-quarters of its peers (97% for the typical peer).

How concentrated its funding is
HEALTH THROUGH WALLS INC leans on a few funders — its largest provides 77% of grant income and the top three 99%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
99% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund HEALTH THROUGH WALLS INC.
Largest funder’s share by year: 2017 100% · 2020 97% · 2021 92% · 2022 100% · 2023 100% — broadly stable.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $192 arriving through sponsors registered in 1 state is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been.
