San Diego wealth management firm Hokanson Associates is merging with Los Angeles-based Aspiriant, the companies said Tuesday, in a deal expected to be completed by the end of December.

Hokanson, with $570 million in assets under management, will become the San Diego office for the much larger Aspiriant, with $8.4 billion under management. Hokanson partners will become owners of Aspiriant and all 12 Hokanson employees will receive job offers.

“(The merger) will give us a larger dedicated professional team with the kind of talent and expertise clients value and we’ll be able to offer a greater breadth and depth of investment and financial planning resources,” President Neil Hokanson said.

The San Diego office will become Aspiriant’s ninth office in the country.
