Robert M. Wilson has resigned from his position as president and CEO of Cambridge Savings Bank. Wilson will remain a member of the bank’s board of directors. He had been on a medical leave of absence since June.

"Cambridge Savings Bank deeply appreciates Bob Wilson’s record of service to the bank and to the communities it serves," Alan McClennen, Jr., chairman of Cambridge Savings Bank and the bank’s holding company, Cambridge Financial Group, said in a statement. "Everybody associated with the bank has been heartened by the tremendous strides Bob has made since taking leave and we look forward to his full recovery."

The board announced that Cambridge Savings has convened a succession committee to identify a new chief executive to lead the bank. Kevin J. Fitzgerald, a former chairman of the bank’s board who has worked with Cambridge Savings for more than 45 years, will continue to serve as acting president and CEO.

Wilson had come to the bank in 1995, and became president and CEO in January 2007. He is a member of the Board of Overseers at the Mount Auburn Hospital and the Board of Directors of the Greater Boston Chamber of Commerce. He is former Chairman of the Cambridge Housing Assistance Fund.
