Current Responsibility

Hillary is an actuary with the Milwaukee office of Milliman. She joined the firm in 2011.


Hillary works in Milliman’s healthcare practice. Her area of expertise is working with organizations that offer Medicare Advantage plans, especially Part D plans. Hillary has also assisted pharmaceutical manufacturers to better understand the Medicare Advantage market.

Hillary’s Medicare Advantage and prescription drug experience includes the following:

  • Assisting multiple Medicare Advantage carriers with strategic planning, bid development, and desk review and audit support
  • Developing competitive summaries of Prescription Drug Plans (PDPs) to evaluate market position and strategy among carriers
  • Assisting an existing PDP carrier with a feasibility study to help decide if they should expand into additional states
  • Creating a complex pricing model to compare the costs to all payers of Part D system of various Hepatitis C prices and rebates
  • Developing and maintaining a web-based tool to allow users to quickly and easily see the impact of benefit designs or plan assumptions changes to a Medicare Advantage bid

In addition, Hillary has been a contributor to the development and ongoing maintenance of CORAL, a Milliman benefit and cost relativity comparison tool. The web-based tool allows employers, insurance companies, and brokers to evaluate the impact of changing medical and prescription drug plan design features, such as deductibles, coinsurance, and copays. It allows users to quickly see the impact those benefit changes have on the plan’s actuarial value and overall cost relative to other plans.
