Current Responsibility

Therese Marske is a consulting actuary and benefits consultant with Milliman in Chicago. She joined the firm in 2000.


Therese has over 25 years of experience in the actuarial field, including consulting with single employer and Taft-Hartley plan sponsors on defined benefit pension plans and retiree medical/life plans. Her experience with these plans includes actuarial valuations, administration of defined benefit plans, lump-sum windows, plan terminations, annual U.S. and international pension accounting (including settlement/curtailment accounting calculations), plan design, and design and preparation of participant benefit statements. With regard to projection tools, Therese presents projection models to clients to assist in the evaluation of a plan’s funded status, minimum contribution requirements, pension accounting costs, and cash flows and in the development of funding improvement plans/rehabilitation plans.

Therese spent six years as an internal actuary for a Fortune 500 company that sponsored a hybrid defined benefit plan, a defined benefit plan for union employees, and a retiree health care plan for all retirees. She was not only involved with the actuarial valuations of these pension and retiree medical plans, but also worked with senior human resource managers on benefit plan design and administration. She worked with senior accounting/financial managers on the annual pension and health plan budgets, long-term projections of plan costs, and the impacts of plan design and assumption changes on annual company results.
