Winning Takes Talent, To Repeat Takes Character.

— John Wooden


Our philosophy of putting our clients and employees first has consistently benefited our shareholders since we started ABB. In an industry where it’s common to be both inactive and reactive, we believe in accessibility, action and accountability; it’s why our clients trust us for counsel and results, and how we achieve long-term success together.

We are not interested in flash in the pan returns, but focused on building a legacy bank for future generations. Our fortress balance sheet has enabled us to continually prioritize quality, and we have done so by sticking to our knitting. Investing in the future involves so much more than focusing only on the numbers; we invest in our clients’ success and in our employees’ development, which has translated into strong results for our shareholders.
