The founding Washington Trust business can date its origins back to 1800, making it the oldest such financial institution in the US.

The Washington Trust Company has rebranded its wealth management offices across Rhode Island, Massachusetts, and Connecticut under one unified name: "Washington Trust Wealth Management."

The name is already used by the company's Rhode Island-based wealth management group, which will now encompass Wellesley, Massachusetts-based Weston Financial Group and New Haven, Connecticut-based Halsey Associates. The firms were acquired by Washington Trust in 2005 and 2015, respectively, but until now retained the use of their own names. 

"Through both organic growth and strategic acquisitions, Washington Trust has built one of New England's premier boutique advisory groups, with more than $7 billion in assets under administration," Edward O Handy III, chairman and chief executive, said.
