Dallmer holds an MBA from the University of Chicago Booth School of Business and a bachelor’s degree in finance and economics from Miami University in Ohio. She received additional training at the London School of Economics and the INSEAD Global Executive Leadership Program in France. Financial News has twice named her one of the 100 Most Influential Women in Finance.

“With the addition of Lisa and her deep operations experience, we are strongly positioned to build on our success as we develop strategies and solutions for clients around the world,” Co-CEO Dave Butler said.
