Effective May 1, Banknorth Investment Management Group has changed its name to Banknorth Wealth Management Group in hopes to identify the firm more clearly with the services it provides, the company announced recently.

A division of Banknorth, N.A., Banknorth Wealth Management Group provides trust and other services to businesses and individuals from 21 offices in Maine, New Hampshire, Massachusetts, Vermont, Connecticut and New York.

“It is a change in name only,” said President Robert B. Esau. Banknorth, headquartered in Portland, is the holding company for Peoples Heritage Bank.
