Mesirow adds $23B in retirement assets with LeafHouse Financial Advisors deal

May 4, 2026 - 22:33

Mesirow has acquired LeafHouse Financial Advisors, adding $23 billion in retirement plan assets to its portfolio. The deal brings the total assets under management and advisement at Mesirow to $138 billion. A key driver of this growth is the network of roughly 10,000 financial advisers who use LeafHouse's fiduciary services.

LeafHouse is known for providing investment consulting and fiduciary support to retirement plans, including 401(k) programs. By folding that unit into its own operations, Mesirow gains a larger foothold in the retirement space without having to build the infrastructure from scratch. The acquisition also strengthens Mesirow's ability to serve plan sponsors and the advisers who manage those accounts.

The move reflects a broader trend in the wealth management industry, where firms are snapping up specialized retirement plan consultants to capture steady fee income. For Mesirow, the deal is a straightforward way to scale its retirement business quickly. The $23 billion in new assets includes both discretionary and non-discretionary accounts, giving the firm a wider base of clients to work with.

Financial terms of the transaction were not disclosed.
