How We’ve Helped New York, NY Nonprofits Grow

Stonybrook Southampton Emergency Room

Stony Brook Southampton Hospital

Stony Brook Southampton Hospital, serving communities across Long Island and New York City, launched a transformational $350 million capital campaign, beginning with a $35 million effort to build new state-of-the-art medical and emergency facilities. Orr Group partnered with the hospital to lead strategic campaign planning, management, and donor engagement.

We developed a comprehensive campaign plan and case for support, identified and cultivated leadership donors, and activated committees that accelerated fundraising for both the new hospital and the East Hampton emergency department.

The momentum was immediate. The East Hampton Emergency Department campaign surpassed its $35 million goal and raised $38 million. Early lead gifts and strong community engagement positioned the hospital to advance its long-term vision to expand access to high-quality care across the East End and the greater New York City region.
