In addition to the VITA program, Lucy has experience in both industry and public accounting, managing and consulting for businesses, assisting taxpayers from tax preparation to representation before the Tax Court, and representing clients at the federal, state, and local levels. Prior to becoming an attorney Lucy managed her CPA practice and worked as a Controller and Accounting Manager for public and International manufacturing companies.

Lucy earned her MBA from the University of St. Thomas in Houston, followed by her JD from the South Texas College of Law Houston. While at South Texas, she earned the University and Texas State Bar Pro Bono Honors award. She was also the President of the Tax Law Society and a member of the Board of Advocates.
