Kansas-based Mariner Wealth Advisors, an independent wealth advisory firm, has appointed William Greiner as chief investment officer.

Greiner, who has over 25 years of industry experience, has left his post as CIO at Scout Investment Advisors and Scout Funds to join Mariner. He started working at Scout’s parent company, UMB, in 1999 as CIO after having worked for Northern Trust in Chicago, the firm said.

In February, Mariner expanded its wealth advisory team with the acquisition of a majority interest in Tulsa's Adams Hall Asset Management.

Mariner Wealth Advisors provides wealth planning, asset management and family office management; the firm has around $8 billion in assets under management and 14 team members.
