Mark Brubaker, head of Wilshire Consulting's outsourced CIO business, left the company, spokeswoman Tess Rodriguez said in an email.
Mr. Brubaker's plans could not be immediately learned. Also a managing director for parent company Wilshire Associates, Mr. Brubaker had been named head of the OCIO business in April 2016.
There are no plans to replace him, Ms. Rodriguez said. Andrew H. Junkin, president of Wilshire Consulting, is now leading the OCIO business, and other colleagues are taking on client responsibilities.
As of June 30, Wilshire Consulting, the institutional advisory and outsourced CIO business unit of Wilshire Associates, had more than $1 trillion in assets under advisement and about $8 billion in discretionary assets under management.
