When people stay, lives change. Here is the proof.
The numbers below are real. They come from six years of showing up in the same neighborhoods, with the same faces, speaking the same languages. This is what consistency produces.
The work, in figures, we can defend.
Cardiometabolic screenings and health education sessions across Greater Boston between 2023 and 2025.
Total participants served.
Screening growth from 2022 to 2025. The demand was always there.
Hypertensive crises caught early, and patients connected to providers and hospitals for care to prevent more serious problems. Twenty-two of those were in 2025 alone.
Around 25% of our participants return, while the industry average is just 8%. At our East Boston location, over half of them come back.
For every dollar invested, the health system sees returns of 8 to 29 dollars by preventing crises and reducing hospital stays.
Fully loaded cost per screening. $60 on a program-only basis.
Behind every data point is a person.
The 47+ hypertensive crises we identified were people who felt fine. Most of them had no idea their blood pressure was dangerous. One of them came to the Mattapan Farmers Market for vegetables.
“I came to the farmers market for vegetables and left with my life. My blood pressure was 182/110. I didn’t feel anything wrong. The health coach found it and got me to a doctor the same day. Six months later, I’m on medication and my numbers are normal.”
Karen, 64, Mattapan
The 3.2x retention rate is not a marketing figure. It is evidence that people trust the health coaches enough to come back. That trust is what makes the next number possible.
The more someone stays, the better their outcomes. We can prove it.
Come once or twice and about a quarter of people see their blood pressure drop. Come six to nine times and it is 74%. The longer someone sticks with a health coach they trust, the better they do.
We can prove it because our health coaches live in the neighborhoods they serve. Because they follow up. Because Ubuntu is not a value statement. It is an operating model.

“HGF is filling a gap our system has never been designed to close. These aren’t just screenings. They are sustained relationships between community members and trusted health advocates. The clinical outcomes are remarkable.”

Community-generated data belongs to the community that produced it.
Our data lives in Essyl, a bespoke HIPAA-compliant platform built by HGF for care coordination and outcome tracking. Every screening, every follow-up, every referral is recorded. The numbers on this page are not estimates. They are drawn from six years of consistent documentation across 19+ active sites in 10 Greater Boston neighborhoods.
We share this evidence with clinical partners, funders, and researchers because community-generated data belongs to the community that produced it.
We see you before, during, and after.
We are there before a crisis happens, alongside clinical care when it does, and following up after. A community health worker who knows your name, speaks your language, and will be back next month does not replace your doctor. She is the reason you go to your doctor, stay on your medication, and come back when something feels wrong. That is what makes clinical care work better for more people.
“If you have early intervention, you have better outcomes. So screening matters. Access is not equal across the board, and neither is health care.”
Patricia Nunn, RN, Lead Health Coach, Heart of a Giant Foundation
