Olney-based Sandy Spring Bancorp, the parent company of Sandy Spring Bank, has completed the acquisition of Rembert Pendleton Jackson (RPJ), a financial planning and investment advisory firm located in Falls Church, Va.

“The reputation, culture and long-tenured staff of Rembert Pendleton Jackson complement our organization and expand the wealth management services we can offer our clients,” said Lou Caceres, executive vice president of the bank. RPJ will continue to operate as Rembert Pendleton Jackson, and Charles Rembert, principal, will lead the company as chairman and CEO. He will report to Caceres.

RPJ was founded in 1974 and currently has more than $1.3 billion in assets under management; the combined AUM under Sandy Spring Bank’s wealth management arms is now approximately $4.5 billion.
