Current Responsibility

Becky is a principal and consulting actuary in the Hartford office of Milliman. She joined the firm in 1986.


Becky has extensive technical and consulting experience in all aspects of defined benefit pension plans, including actuarial valuations, experience studies, accounting calculations, plan design, employee communications, and modeling. She supervised the processing of numerous plan terminations, including calculation of benefit entitlements, employee notification and government filings, and distribution of plan assets. She organized and managed the work flow for the annual valuation of a major state plan. Included in this annual work was a detailed actuarial gain/loss analysis. Her expertise also includes the data analysis involved in the five-year experience investigation for this 80,000 member system.
