R. Parker Sheffy

Legal & Advocacy Director

Parker Sheffy is Legal and Advocacy Director whose life experiences caused his personal and professional interests to center around economic mobility and social equity. Specifically, he is interested in how the legal system creates and defines individual’s identities as members of a group and how the law can be used to empower, rather than hinder, individuals with agency over their lives, to be able to have a meaningful opportunity at securing their definition of the “American Dream.” As a Native Houstonian, he is passionate about this City—believing creating a more equitable Houston will have an outsized positive impact upon the State’s, and therefore the Nation’s, trajectory. The combination of these passions and beliefs bring him to HILSC, where he hopes and plans on contributing towards creating that more equitable, empowering Houston.

Prior to joining HILSC, Parker worked in positions with the common theme of learning about and empowering marginalized communities, while simultaneously engaging with the legal and political systems whose decisions disproportionately and most immediately impact individuals living on the margins. He was a Community Organizer with the 2012 Obama campaign, focusing on Southeast Houston and Pasadena, taught Algebra at a public high school in the South Bronx, clerked in both chambers of the U.S. Congress, as well as for the ACLU of Alaska. Upon becoming a licensed attorney in 2017, he began his career at Houston’s Catholic Charities St. Francis Center for Immigrant Legal Assistance, providing direct representation to thousands of individuals in a high volume, economically resourced non-profit during a period of rapid changes to federal immigration policy and enforcement and heightened political rhetoric and disinformation directed at certain immigrant communities. Parker comes to HILSC from the University of Houston Law Center (UHLC), where he continues to work part-time, as a Clinical Supervising Attorney in the Immigration Clinic. At the Clinic, he represents indigent immigrants with wide ranging immigration-based legal problems, focusing upon complex federal litigation, while supervising and teaching Houston’s future immigrant advocates, UHLC law students.

He is a graduate of Georgetown Law, where he earned a J.D., St. John’s University in New York City, where he earned a Master of Science in Education, and The University of Texas at Austin, where he earned a B.A. with a dual major in Economics and History. If not at the office, you can likely find him walking Buffalo Bayou listening to podcasts and audiobooks.
