Verified Voting Team

As the President of Verified Voting, Marian Schneider brings a strong grounding in the legal and constitutional elements governing voting rights and elections, as well as experience in election administration at the state level. Immediately before becoming President of Verified Voting, Marian served as Special Advisor to Pennsylvania Governor Tom Wolf on Election Policy. Previously, Governor Wolf appointed her as the Deputy Secretary for Elections and Administration in the Pennsylvania Department of State where she served from February 2015 until May 2017.

Under Marian’s leadership, the Department launched Pennsylvania’s online voter registration application. Embraced by voters all over Pennsylvania, more than 950,000 voters have used the application to register or update their registration. Marian introduced numerous reforms including improving universal usability of the voter registration application, re-issuing policy guidance on important election issues, clarifying the instructions to voters in PennDOT’s “Motor Voter” screens, requiring translations of the motor voter screens into 12 additional languages and implementing revisions to the Department’s flagship voter information website to improve public access to critical elections information. Marian also championed membership in the Electronic Registration Information Center and served as the inaugural PA member of the ERIC Board of Directors. Marian also served as the Pennsylvania state election official on the EAC’s Standards Board and on the Pennsylvania Advisory Committee on Voting Technology to the Joint State Government Commission.

Throughout her legal career, Marian has focused on the intersections of civil rights and election law. Formerly, she was a Senior Attorney with Advancement Project’s Voter Protection program and was trial counsel in Applewhite v. Commonwealth, successfully challenging Pennsylvania’s restrictive photo ID law on behalf of voters as an unconstitutional infringement on the fundamental right to vote. She represented the plaintiffs in the successful 2008 case under § 2 of the Voting Rights Act against Chester County for failure to move the inadequately-sized Lower Oxford East polling place to a more spacious polling place on the Lincoln University Campus. The lack of an adequate polling place resulted in 6-8 hour waiting times in a precinct comprised primarily of African-American voters in the 2008 presidential election.

Marian received her J.D. from The George Washington University, where she was a member of the Law Review, and earned her B.A. degree cum laude from the University of Pennsylvania.
