Citizens Bank continues expanding its wealth management heft, most recently signing a definitive agreement to acquire a multibillion-dollar independent wealth management firm and multi-family office based in New York that would almost double the bank’s assets under management, according to a press release from Citizens Financial Group, the parent company of Citizens Bank.

Tarrytown, N.Y.-based Clarfeld Financial Advisors had around $6.6 billion in assets under management and $900 million in assets under administration as of the end of September, Citizens says.

Clarfeld’s team, which includes certified financial planners, accountants and lawyers, takes a multi-disciplined approach to serving high net worth and ultra high net worth clients and families, according to the press release.

With the acquisition, Citizens Bank will have around $14.4 billion in assets under management and a combined $34.1 billion in combined assets under management and under advisement, the company says. The deal is expected to close by early next year, according to Citizens Bank.

“The Clarfeld acquisition provides a unique opportunity to accelerate our strategy of building a highly competitive wealth management business that is well-positioned to offer a comprehensive range of wealth management and banking services to existing and future clients,” John Bahnken, president and CEO of Citizens Bank Wealth Management, says in the press release.

Robert Clarfeld, founder and CEO of Clarfeld, will be named CEO of Citizens Bank’s combined high net worth and ultra-high net worth businesses, Bahnken says in the press release.

Citizens Bank has been investing in its technology to boost its wealth management offerings in recent years. Most recently, the company signed up as the first client on SigFig’s wealth management platform that automates various administrative tasks.

Last year, Citizens Bank rolled out a robo-advisor in partnership with SigFig.
