About Daniel Martin
Daniel Martin Hartzman built a legal path that moves between classrooms and courtrooms. He earned a B.A. from the University of Virginia in 2007 and completed his J.D. at the University of Pennsylvania Law School in 2011. Those years shaped his approach to practice: rigorous classroom debate followed by practical problem solving.
After law school, Hartzman began work that would lead him into immigration law. Over time he gained admission to practice in Pennsylvania, the District of Columbia, and Virginia. He joined professional organizations early in his career and has maintained ties to national and local groups that address immigration and bar matters.
His professional affiliations include membership in the American Immigration Lawyers Association since 2016 and participation in the Allegheny County Bar Association in 2016. Those memberships reflect the circles where he has exchanged ideas and kept current on evolving rules. They also mark a shift from classroom theory to the administrative and court processes that shape clients’ lives.
Hartzman serves as the principal lawyer at Hartzman Law Office, LLC. In that role he manages case intake, oversees filings, and handles hearings. The office work ranges from asylum petitions and family-based immigration filings to removal defense and administrative appeals. He balances courtroom appearances with the paperwork and client meetings that immigration matters require.
Colleagues describe him as methodical in preparing cases and direct in courtroom settings. He tends to break complex regulatory materials into clearer steps for clients. That approach reflects his training at Penn and at UVA, where rigorous analysis and structured argument were part of the curriculum. He applies the same discipline to client interviews, document collection, and the procedural calendars that often determine a case’s course.
Hartzman’s practice sits at the intersection of federal procedure and individual stories. He spends much of his time drafting petitions, compiling evidence, and representing clients in hearings before immigration adjudicators. He keeps abreast of changes in policy and precedent through ongoing association work and by following administrative developments in the jurisdictions where he is licensed.
He currently leads Hartzman Law Office, LLC, where his practice centers on immigration law and related administrative matters.
