Boston’s Back Bay Financial Group Inc. and Westwood, N.J.-based Modera Wealth Management have completed its merger and will operate as Modera Wealth Management LLC.

The merger, more than a year in the making, creates a wealth management firm with more than $900 million in assets under management, approximately 550 clients and 28 employees, according to a statement.

"Consolidation of operations strengthens the independence clients have said they desire and value," said John H. LeBlanc, principal, Modera. "The two firms began informal discussions more than a year ago and quickly realized they shared similar values and a common approach toward financial planning."
