“If you have early intervention, you have better outcomes. So screening matters. Access is not equal across the board, and neither is health care.”

We show up for our neighbors, every week.
We’re a community health organization rooted in Mattapan, Dorchester, and Roxbury, serving neighborhoods across Greater Boston. Our community health workers live and work in your neighborhood. They offer free blood pressure checks, diabetes screening, and kidney checks, along with referrals and health education. Some results are ready on the spot. Others take a day to a couple of weeks, and we’ll follow up with you when they’re in.
It costs nothing, and you don't need insurance or paperwork.
No doctor? We’ll help you find one.

The Ubuntu Spirit
“I am because we are. My survival was a gift from a community. Now we give it back.”
Built from the inside out.
Heart of a Giant Foundation was founded by Bouba Diemé, the man behind the name, who received a heart transplant at Brigham and Women’s Hospital in October 2022.
Six years on the waiting list. Nearly six years living with a mechanical heart pump. The relationships that sustained him through his illness became the design brief for the organization he built.
“My goal is to use my lived experience to help eliminate preventable harm and improve the management of chronic health conditions in our communities.”
Bouba Diemé, Founder
From our team
Clinical training, local roots.
Many of our community health workers, staff and volunteers alike, are also licensed or certified health professionals. They include registered nurses, a nurse practitioner, certified medical assistants, a pharmacist, a dental hygienist, and social workers. Others come from the neighborhoods we serve and complete HGF’s community health worker training.
“Trust isn’t built on credentials. It’s built on shared experience.”

Every gift keeps a community health worker at a screening table this week.
“The people are all the goodwill, all the support, all the love we’re getting. It must come from people that have a big heart, the heart of a giant.”
Every gift funds screenings, follow-up visits, and the health workers who keep showing up.
