A dependable, outsourced fiduciary specialist

We provide fiduciary solutions, co-manufactured investment vehicles, asset allocation programs and personalized managed accounts to serve a broad range of stakeholders across the retirement, IRA and HSA markets.
Today, our proprietary FlexFiduciary service continues uninterrupted and is supported by Mesirow’s established Fiduciary Solutions platform. Leveraging the firm’s scale, investment expertise, and operational infrastructure—along with 20 years of leadership in outsourced fiduciary services—we deliver consistent, high-quality outcomes for plan sponsors and participants.
