401k Plan Professionals - 2026 Fiduciary Training Series for Retirement Plan Sponsors

February 2026 - Fiduciary Fundamentals

June 2026 - Fiduciary Best Practices

October 2026 - Fiduciary In Action

In this February 2026 training, our advisor, Jenna Witherbee discusses Fiduciary Fundamentals. We compiled a list of the Top 10 Responsibilities for Retirement Plan Fiduciaries aka Plan Sponsors. Whether your organization has a 401k or a 403b, this information is pertinent to you as a fiduciary to your plan.

Please notice the key that is included on each step in the upper left-hand corner. Certain fiduciary responsibilities are for the entire Plan Committee or Named Fiduciary, while others apply more to a Human Resources / Benefits / Payroll professional, a Chief Financial Officer / person working in a finance role, or in some cases, the advisor to the plan. Our team serves as a fiduciary and the advisor to our client’s plan.

Below is the list that Jenna Witherbee discusses in the 30-minute webinar recording.
