Judith R. Faulkner

Faulkner was born on August 11, 1943, to Louis and Del Greenfield. Faulkner's parents inspired her early interest in healthcare; her father, Louis, was a pharmacist, and her mother, Del, was the director of Oregon Physicians for Social Responsibility. She was raised in the Erlton neighborhood of Cherry Hill, New Jersey, and graduated from Moorestown Friends School in 1961. She received a bachelor's degree in mathematics from Dickinson College and a master's degree in computer science from the University of Wisconsin–Madison.

While getting her master’s degree, Faulkner took a course on computing in medicine under Dr. Warner Slack. She was tasked with developing a system to keep track of patient information. In 1979, shortly after receiving her master's degree, Faulkner co-founded Human Services Computing, with Dr. John Greist. Human Services Computing, which later became Epic Systems, began in a basement at 2020 University Avenue in Madison, Wisconsin. The company was started with a $70,000 investment from friends and family but has never taken investment from venture capital or private equity and remains a privately held company. Faulkner prides herself in the fact that Epic is homegrown; they have never acquired another company, and Faulkner has stated they will never go public. Epic Systems now holds the medical records of over 325 million people. Faulkner and her family currently own 43 percent of Epic Systems.

Faulkner lives in Madison, Wisconsin. She is married to Gordon Faulkner, a pediatrician, and they have three children.

In 2015, Faulkner signed The Giving Pledge, committing 99% of her assets to philanthropy. In 2019 Judy and Gordon founded the Roots & Wings Foundation, which funds nonprofit organizations that serve low-income children and families.
