Atlantic Bank would have marked a century of history in New York in 2026. Instead, its centennial arrives with the familiar name gone from the city’s banking landscape and its last president looking back at an institution that, for generations of Greek Americans, represented far more than a place to deposit money.
“The Star of Atlantic Bank Has Gone Dark,” Nancy Papaioannou, the bank’s final president and CEO, told exclusively Greek Reporter reflecting on the institution’s history and disappearance.
For Papaioannou, Atlantic Bank’s story cannot be measured simply through mergers, balance sheets and branch networks. It is a story of immigrants opening their first bank accounts in America, entrepreneurs securing financing for businesses, families buying homes, and generations of Greek Americans walking into a bank where someone behind the counter might speak their language and understand where they came from.
“Atlantic Bank was never just its buildings, its branches, or its logo,” Papaioannou said. “Atlantic Bank was its people.”
A Greek bank takes root in New York
Atlantic Bank’s history began in 1926, when Bank of Athens Trust Company, a subsidiary of Greece’s Bank of Athens, received a banking charter in New York State. The institution later became part of National Bank of Greece and, in the early 1950s, emerged under the name Atlantic Bank of New York.
Over the decades, the bank expanded through acquisitions and established itself across New York City and the surrounding region. Its identity, however, was closely tied to the Greek-American community. Atlantic was not simply a bank owned at one stage by a major Greek financial institution. It became part of the infrastructure that helped successive waves of Greeks establish themselves in the United States.
Its branches served families, professionals, small businesses and community organizations. Greek could often be heard alongside English, and relationships between customers and bankers frequently extended well beyond financial transactions.
That role was still evident decades later. In a Greek Reporter feature on Atlantic Bank and its relationship with Greek Americans, Papaioannou described a banking culture built around personal relationships and trust. For many customers, the bank knew not only their businesses but their families.
The Herald Square branch and a familiar piece of Greek New York
Among Atlantic Bank’s best-known locations was its Herald Square branch in Manhattan, across from Macy’s.
Thousands of business owners, professionals and families passed through its doors over the years. Papaioannou remembers customers being able to pick up Greek-language newspapers while waiting to conduct their banking. It was a small detail, but one that captured what distinguished Atlantic from a conventional American bank.
For a newly arrived immigrant, dealing with a financial institution could be intimidating. At Atlantic, there was a good chance that somebody understood not only the customer’s language but also the experience of beginning again in a new country.
“A bank was not merely where you deposited money,” Papaioannou recalled. “It was often where you opened your first account, obtained financing for your business, bought your first home, established your credit and began building a future for your family.”
The bank also maintained close relationships with Greek-American churches, associations, businesses and community organizations and for decades supported events including New York’s Greek Independence Day Parade.
In Papaioannou’s telling, the institution became woven into the community because its employees were part of that community themselves. Tellers, branch managers, executives, operations staff and customers saw one another at churches, community events, weddings and christenings.
“Together, they formed what was, in many ways, the Atlantic Bank family,” she said.
Atlantic Bank sold for $400 million
A major change came in 2006. National Bank of Greece sold Atlantic Bank of New York to New York Community Bancorp for approximately $400 million. The deal brought Atlantic’s operations into what became the Atlantic Bank Division of New York Commercial Bank. SEC records show that Atlantic had about $2.8 billion in assets and $1.8 billion in deposits when the acquisition was completed in April 2006.
Yet the Atlantic Bank name survived.
That mattered to the Greek-American community. Although ownership had changed, customers continued walking into branches bearing the Atlantic name, and many of the relationships that had developed over generations continued. As late as 2022, Atlantic operated 11 full-service branches and retained a distinct identity within New York Community Bank. Papaioannou herself credited NYCB at the time with giving Atlantic the scale and resources to remain competitive while preserving its relationship with the community.
Nancy Papaioannou becomes Atlantic Bank president
Papaioannou’s own story became intertwined with the bank’s final chapter. She arrived in the United States in November 1990 and built her career gradually, working during the day while studying at night. She describes beginning from a modest position and learning banking from the ground up.
On July 31, 2014, she was elected president of Atlantic Bank. Her rise also carried significance beyond Atlantic Bank. In 2017, Greek Reporter profiled Papaioannou as the first Greek-American woman to serve as president of a bank in New York.
“It was one of the greatest honors of my professional life,” Papaioannou said of leading Atlantic. She would ultimately become its final president.
The weekend the Atlantic Bank name disappeared
For an institution with nearly a century of history, the visible end came remarkably quickly. Papaioannou remembers customers being informed that Atlantic Bank would cease operating under its familiar name during the Presidents Day weekend of February 2024.
The branches would reopen under the Flagstar name. “The signs came down,” she recalled. “The familiar Atlantic Bank name disappeared from the branches. And new signs went up.”
The change was part of a much broader corporate consolidation. New York Community Bancorp had acquired Flagstar Bancorp in 2022 and later moved to unify its banking operations under the Flagstar brand. On February 21, 2024, the company announced that it had completed the systems conversion and introduced Flagstar branding throughout its branch network.
For customers of a national financial institution, a change of signage might appear routine.
For those who had known Atlantic for decades, Papaioannou said, it felt different.
“It took only a long weekend for an institution that had been part of the Greek-American community for generations to disappear from the public landscape,” she wrote.
A centennial without Atlantic Bank on the sign
A century has passed since Bank of Athens Trust Company received its New York charter, yet there is no Atlantic Bank centennial celebration and no Atlantic sign over a branch door. The institution’s corporate life was absorbed into larger banks long ago, but its distinct identity endured far longer than its independence.
That identity is what Papaioannou believes deserves to be remembered. “The story of Atlantic Bank is not simply a story about mergers, acquisitions, branches and corporate transactions,” she notes. “It is the story of immigrants, entrepreneurs, families, employees and generations of Greek Americans who believed in building something lasting in America.”
Atlantic’s history also mirrors the evolution of the Greek-American community itself. Immigrants who once needed a bank where they could conduct business in Greek built companies, bought property, sent children to college and established families whose connection to America was no longer new. Institutions such as Atlantic helped bridge those worlds.
As the community changed, so did the bank.
What endured longest was the sense that it belonged, in some measure, to the people who had grown up with it.
“Goodnight, Atlantic Bank”
Papaioannou does not describe the end of Atlantic simply as the disappearance of a corporate brand.
For her, it meant the closing of a chapter shared by thousands of employees and customers. Some of the people she worked with have died. Others retired or continued their careers elsewhere. Customers who first walked into Atlantic decades ago have passed businesses and homes to their children. The bank itself no longer carries its historic name. But the relationships and memories created around it remain.
“History is not erased by removing a sign,” Papaioannou says. “The memories remain. The people remain. The lives that were touched remain. And the legacy remains.”
A hundred years after the institution’s beginnings, she remains proud to have led it through part of its final chapter.
“For me, Atlantic Bank was not simply a job,” Papaioannou said. “It was a responsibility. It was a community. It was a piece of Greek-American history. And it will always be a part of my life.”
