Born and raised in Austin, Margo attended Georgetown University in Washington, D.C., where she received her B.S. from the Walsh School of Foreign Service and majored in Science, Technology and International Affairs. While in Washington, Margo was an active member of the Georgetown University College Republicans, serving in multiple leadership roles.  She was a frequent volunteer on the campaigns of Republican congressional and state candidates and interned on Capitol Hill for the then-senior U.S. Senator for Texas.

Cardwell returned to Austin to attend law school at the University of Texas. During this time, she worked for one of the state’s largest trade associations, where she drafted legal documents and policy memoranda that proved central to accomplishing the association’s key legislative priority during the 82nd Legislative Session.

After graduating law school, Margo served as General Counsel to a Republican Texas state senator. Following the 83rd Legislative Session, Margo joined Greg Abbott’s historic gubernatorial campaign during the 2014 election cycle, where she was the chief policy analyst. As a leading member of the policy team, Margo was instrumental in developing campaign policy on education, health care, natural resources, and criminal justice.

Prior to establishing Margo Cardwell, PLLC, Cardwell was employed at one of Austin’s top advocacy firms, where she represented the firm’s clients – spanning a myriad of industries – before the Texas legislature and the executive branch of state government.

In addition to her work as a legislative advocate, Margo is an accomplished attorney and one of the state’s few ethics lawyers. In this capacity, Margo advises legislators, statewide officeholders, and PACs on Texas election and campaign finance law.

Outside of the Capitol, Margo enjoys traveling and spending time outdoors with her husband and the couple’s two yellow labs, Tank and Deets.
