Cambridge Bancorp in Massachusetts will soon have a new president and chief executive.

The $1.6 billion-asset company said in a press release Monday that Denis Sheahan will also become its chairman on April 1. He will succeed the retiring Joseph Roller 2nd, who has led Cambridge for 13 years.

Sheahan is the chief operating officer at Independent Bank in Rockland, Mass.

"This management transition comes at a time of strength as Cambridge … continues on a path of solid growth," Linda Whitlock, who chaired Cambridge's search committee, said in the press release.

Cambridge has 12 branches in Massachusetts.

Banco Santander named a new chief executive for its unit that serves as the holding company for its U.S. retail bank, Santander Bank, and its subprime auto lender, Santander Consumer USA Holdings.

Santander Holdings USA, the holding company, named Scott Powell as CEO, replacing Román Blanco in that role. The appointment of Powell, the former head of banking and consumer lending operations at JPMorgan Chase, took effect Monday. Blanco will remain chief executive of the $80 billion-asset Santander Bank.

Powell for the last two years had been chairman of National Flood Services. He worked for JPMorgan and one of its predecessors, Bank One, from 2002 to 2012 in various jobs, according to his LinkedIn page. Before that he spent 14 years in risk management at Citigroup.

"[Powell's] expertise and experience in retail banking, consumer finance and risk management will be a great contribution as we work to improve customer service, enhance our U.S.-wide oversight and embed our banking culture across the U.S.," Ana Botín, chairman of Banco Santander, said in a press release.

Powell's appointment is the latest personnel move in Santander's executive ranks in recent months. Jose Antonio Alvarez on Jan. 1 was promoted from chief financial officer of Banco Santander to CEO. Ana Botín was named chairman last year after her father, Emilio Botín, passed away at age 79. The elder Botín had led the company since 1986.

Also on Monday, Banco Santander said it will consolidate two additional subsidiaries into Santander Holdings USA. The $5.5 billion-asset Banco Santander Puerto Rico, the company's retail bank in Puerto Rico, and Banco Santander International, a private bank in Miami, will be integrated into Santander Holdings USA by the middle of this year. Those units had been organized directly under the Spanish parent, Banco Santander, according to the Federal Reserve.

Santander Holdings USA owns all of Santander Bank, and 60.5% of Santander Consumer USA Holdings.

BancorpSouth in Tupelo, Miss., is planning to add a former Bank of America executive to its board.

Deborah Cannon has been the president and chief executive of the Houston Zoo since 2005. Cannon worked at Bank of America for 30 years before stepping down as an executive vice president in 2004. She is expected to join BancorpSouth's board during its annual meeting in April.

While at Bank of America, Cannon's responsibilities ranged from leading the company's offices in Brazil, Argentina and Chile to starting a new division for affluent individuals. Before leaving B of A, she led a business banking unit that covered 10 states and had more than 50 offices, $3 billion in loans and more than $4 billion in deposits.

The addition also strengthens BancorpSouth's ties to Texas, where it has been opening loan-production offices. In addition to her time at the zoo, Cannon once worked at Republic National Bank of Dallas.

Pamela Joseph, U.S. Bancorp's vice chair of payment services and a 10-year veteran of the Minneapolis-based bank, plans to retire in mid-2015.

Joseph will be succeeded by Shailesh Kotwal, who is scheduled to join the bank at the end of the first quarter. Kotwal's experience in the payments industry includes executive roles at TD Bank, Fidelity National Information Services and American Express.

Joseph has been on the front lines as U.S. Bank responds to the myriad technology challenges impacting the payments industry. She has been repeatedly honored as one of PaymentsSource's Most Influential Women in Payments and one of American Banker's Most Powerful Women in Banking.

"One of Pam's most significant and lasting contributions to U.S. Bank is the strong leadership team she has established across her global organization, which will allow us to continue expanding our presence in the payments market," Richard K. Davis, U.S. Bancorp's chairman, president and chief executive, said in a press release Friday.

Most recently, Joseph was involved in U.S. Bank's response to the release of Apple Pay, which she says will breathe new life into prior mobile payment plays that didn't pan out, such as contactless payments and wearables.

Bankwell Financial Group in New Canaan, Conn., didn't have to look far to find a permanent leader.

The $900 million-asset company said in a press release Friday that Christopher Gruseke has become its president and chief executive. Gruseke, a founding investor in Bankwell, was hired last month as the company's chief strategic officer.

Bankwell said last month that Gruseke was being considered for the CEO vacancy created last fall when Peyton Patterson resigned shortly after it was revealed that a judge had ordered her to pay more than $350,000 in unpaid credit card bills. Blake Drexler, Bankwell's chairman, had been filling in temporarily while the company sought out a permanent replacement for Patterson.

Gruseke's financial services experience includes serving as a member of CRT Capital's executive committee and as a chief operating officer at Greenwich Capital Markets.
