Welcome to ABOC

In July 2024, Amalgamated Bank of Chicago ushered in a new era by rebranding as "ABOC." The new name and look reflect the Bank's embrace of a forward-looking, digital-first philosophy while retaining the principles -- such as responsible banking practices and a commitment to excellent service -- that has made ABOC successful for over a century. Though ABOC continues to evolve and grow, the bank is built on a strong foundation.
