Strategy Work at Optum
She came up through AIM Healthcare as vice president of data mining technologies, then was vice president and general manager of strategy and emerging solutions at Optum. In 2005 the National Business Journal honored her as a Woman of Influence.

She co-founded Xsolis in 2013. In 2020 the company released CORTEX, a product line for hospital physicians, to flag medical necessity and the financial risk of a stay.
Handing Xsolis to Lee Rivas
In October 2026 Xsolis appointed Lee Rivas, the former chief executive of Cloudmed and R1 RCM, as its new CEO, succeeding Butters after 13 years in the role. Looking back in the announcement, she said: "Thirteen years ago, a healthcare executive told me that what we're doing today couldn't be done. I'm proud to have led a team that proved him wrong."
