West Los Angeles wealth management firm Aspiriant announced Monday that it would merge with Silicon Valley advisory outfit Stanford Investment Group.

As part of the merger, Stanford Investment Group’s $850 million in assets under management will be added to Aspiriant’s $9.5 billion, pushing the firm’s total money controlled above the $10 billion mark. Stanford’s employees will become employees of Aspiriant, with five becoming partners.

The merger is the third expansion move undertaken by Aspiriant this year, according to the company. The transaction is expected to close by the end of January. Stanford Investment Group is not associated with Stanford University.
