Welcome Optima Bank & Trust Clients


We are pleased to announce that the merger between Cambridge Trust and Optima Bank & Trust closed on April 17, 2019. We’re excited to create an even stronger institution for our clients as one bank, one brand. The combined company preserves the strengths of Optima Bank, expands Cambridge Trust’s existing New Hampshire presence, and enhances the private banking experience with a full suite of lending, deposit, and contemporary wealth management solutions to meet personal and business needs.
Over the weekend of July 19, your Optima accounts will transition to Cambridge Trust’s systems. You’ll receive a mailing in mid-June with additional details. In the meantime, check back here for the most up-to-date information to help you with the transition.
