South Street Securities is proud to announce that we will attending the Fiver Children’s Foundation 2026 Annual Benefit on May 14th, 2026 at 583 Park Avenue. The sit-down dinner will bring together the Fiver community and celebrate the contributions made to advance Fiver's mission.
The event celebrates Fiver's mission of empowering youth across New York through a bold and proven model of long-term, no-cost support. The unique ten-year promise to each child makes Fiver a part of their lives, walking alongside them through the formative chapters of their youth. From summer camps to academic mentoring, the programs build confidence, resilience and leadership in ways that last far beyond childhood. Fiver provides youth from systematically under-resourced communities in New York with experiences that challenge and relationships that nurture so they can create their own positive futures.
Donald Webbe, Chief Operating Officer of South Street Securities Holdings, will be recognized at the benefit as the honoree of the Richard Adam's Leadership Award. His contributions over the years have allowed Fiver to provide youth across New York with the resources they need to succeed past their youth.
South Street Securities has been supporting Fiver since 2012 and Donald Webbe has been a big advocate for Fiver's mission, alongside Jim Tabacchi, CEO of South Street Securities Holdings. The firm has consistently supported Fiver's mission through their annual benefit sponsorship, highlighting South Street Securities' commitment to empowering New York area youth to create their own positive futures. Webbe has many close ties to the Fiver community, including several of the founding board members and longtime supporters, including James Roper and Steve Carlson, among many others Fiver supporters.
