About Jeffrey A
Jeffrey A Jansen earned a Bachelor of Science from the United States Air Force Academy, where he studied behavioral sciences and human factors engineering and graduated in 1984. He later returned to school for law and received his Juris Doctor from the University of Texas at Austin in 1993. Those two degrees anchor a career that blends technical training and legal education.
After law school, Jansen pursued legal practice that spans both state and federal jurisdictions. He is admitted to practice in Texas and before the United States Court of Appeals for the Fifth Circuit. Those admissions shape the work he accepts and the forums where he represents clients. Over the years he has handled matters that require attention in trial courts and on appeal.
Early on, Jansen’s background suggested an interest in areas where human factors and systems intersect with law. He brought an analytical approach to case assessment and fact development, and he applied methodical problem solving to evidence and testimony. That orientation has informed his litigation style. He tends to emphasize clear record-building and thorough briefing, particularly in matters that may reach appellate review.
Jansen later established the Jansen Law Office, PLLC. The firm serves clients from its office in Texas and manages matters that arise under state law as well as appeals filed in the Fifth Circuit. At his practice, he handles contested issues, prepares appellate filings, and appears in hearings and court conferences. The office environment reflects a small-firm model: direct contact between attorney and client, and a focus on resolving procedural and substantive questions efficiently.
Colleagues describe Jansen as careful in preparation and direct in court. His training at the Air Force Academy and at UT Austin inform how he organizes case strategy and how he presents legal analysis. He has routinely prepared written advocacy for district courts and for appellate panels, and he adjusts argument style depending on the level of review and the nature of the record.
Outside of court, Jansen maintains familiarity with appellate practice rules and local procedures that affect briefing and oral argument. He tracks developments from the Fifth Circuit and Texas courts that bear on his clients’ interests. He also prioritizes clear communication about timelines and steps in litigation, so clients understand where a case stands and what decisions they face.
Jansen currently practices at Jansen Law Office, PLLC, representing clients in Texas courts and in appeals before the Fifth Circuit. He concentrates his practice on litigation and appellate representation.
