Aaron Ramthun is a financial professional with more than 20 years of experience working across the healthcare finance field, including Medicare bids, Medicaid rate book reviews, and budgeting. Aaron has a demonstrated track record of improving operational efficiency and implementing innovative forecasting practices. He is skilled in financial modeling, determining the financial viability of entering a new product or geographical area, and predicting the financial implications of Dual Eligible Special Needs Plan supplemental benefits, changes to quality measures, and Star rating changes.

Before joining HMA, Aaron was associate director of finance and, previously, finance manager of UnitedHealthcare’s Medicare and Retirement’s complex care products. In these positions, he provided focused financial direction to the portfolio and coordinated the development of the five-year long-range model by incorporating known factors, estimating risk-adjustment factors, providing actuarial guidance on medical trends, anticipating membership volumes, and understanding impacts from strategic investments. He incorporated foreseeable market forces into the quarterly forecast process and generated a product-oriented monthly reporting package on current performance versus forecast expectations, engaging cross-functional partners in field finance, actuary, marketing, sales management, and healthcare affordability teams.

During this time, Aaron also assisted UnitedHealthcare’s Community and State segment as the interim community plan market CFO. He led a cross-functional team to complete contractually required financial statements for the Commonwealth of Massachusetts, including income statements, encounter-to-financial crosswalks, and annual rate-setting documents. Further demonstrating his collaboration skills, he partnered with plan leaders to identify market developments and worked with clinical and operations leaders to avoid duplicative positions and invest in needed roles, allowing him to correct performance gaps that directly impacted revenue payments. Aaron also developed segment resources to improve market forecasting accuracy, annual budgets, and long-range business plans.

Before joining UnitedHealthcare, Aaron worked with Ecolab Inc. as an associate financial analyst, a financial analyst in the textile care division, and a senior financial analyst in corporate planning and analysis. As a senior financial analyst, he summarized and reported on business performance related to strategic investments, analyzed gross margins, and reviewed cash flow variance. Aaron created new processes that generated thoughtful analysis and actionable details for the operational review package. He also used the Lean Six Sigma framework to create and implement standardized templates and reporting methodologies to accurately detail results and forecast future periods.

Mr. Ramthun earned his Bachelor of Science degree in accounting from Globe College and his Bachelor of Arts degree in biology from Saint John’s University.
