It truly is the most wonderful time of the year at Dot House Health. The health center just received the largest single donation in its 150-year history from Yield Giving, the charitable fund established by MacKenzie Scott, the ex-wife of Amazon founder Jeff Bezos.

The actual sum has not been disclosed, but it’s safe to assume that it’s a seven-figure number. It’s one of two major gifts to Boston-area health centers by Scott’s team, which also gave $7.5 million to Roxbury’s Dimock Center. The news of both gifts went live on the Yield Giving website last week.

Yield Giving does not take applications and does not take contributions from any donors. Scott’s mission is to redistribute the majority of her massive fortune by deploying a team of advisors to seek out non-profit organizations that have a “major impact on a variety of causes.” Since 2019, they’ve given out over $16.5 billion to nearly 2,000 non-profits across the world.

Michelle Nadow, Dot House Health’s CEO, had no idea that Yield Giving was even a thing— let alone a potential donor for her Fields Corner-based organization. She got a call from a Yield Giving executive telling her: “You’re a leader in your field and that they’d be giving us an award.”

There were no questions asked, no string attached, no press releases or check presentations. Yield Giving doesn’t require a follow-up report. In fact, they don’t want to hear from DotHouse Health again. It’s a one-time gift.

“It’s a real tribute to the amazing work that’s been done here over our whole history,” said Nadow, who has worked at DotHouse for 19 years, the last eight as CEO.

“I’m so incredibly proud of the work we do here and it’s so incredibly gratifying to have other people notice your work and want to invest in it,” said Nadow. “It really makes us feel like we are an anchor here and that we need to make sure we’re here in perpetuity to meet the needs of the community.”

It’s been tough sledding for DotHouse— and all community health centers— in the post-Covid era. Megan Sonderegger, who chairs its board of directors, said she and her colleagues “will work diligently to make certain that every bit of this gift is allocated to have the greatest impact for emerging and evolving services and programs at our health center.

“We want to ensure that this gift can continue to help and support DotHouse for years to come,” she said.
