About Philip Andrew
Philip Andrew Prossnitz built his legal foundation at Duke University, where he earned a Bachelor of Arts in 1976, and at Tulane University School of Law, where he received his Juris Doctor in 1980. He completed his formal legal education as the 1980s began and entered a profession that would span multiple decades and more than one jurisdiction.
After law school, Prossnitz established a practice that has navigated the differing procedural and substantive rules of Illinois and Louisiana. He holds licenses in both states and has maintained memberships in professional associations, including the Illinois State Bar. That dual-licensure has shaped the types of matters he has handled and the clients he has represented, allowing him to respond to legal issues that cross state lines or that require familiarity with two separate legal systems.
Colleagues describe his approach as methodical. He tends to break complex questions into their component parts and address them in sequence. That style shows in courtroom filings, negotiation letters and client counseling. Over a long career, he has worked on litigation and transactional matters. He has appeared in state courts and prepared pleadings, motions and briefs. He has also advised clients on contractual and regulatory issues that touch on local practice in Illinois and Louisiana.
Prossnitz’s professional affiliations have kept him engaged with the bar and with continuing legal education. His active membership in the Illinois State Bar indicates a connection to legal developments and networking opportunities in that state. Maintaining bar status in two jurisdictions requires attention to differing continuing education requirements and to changes in court procedures. That administrative work has been a steady part of his practice backdrop.
Clients and peers have relied on him for practical legal work rather than for publicity. He has handled matters that require careful document review, calm negotiation and precise courtroom presentations. His practice reflects steady client service across a range of issues rather than a narrow specialization. That breadth has been one of the constants of his professional life.
As of 2026, Prossnitz continues to practice law in the jurisdictions where he is licensed, attending to civil matters that arise under Illinois and Louisiana law and providing counsel to clients whose needs intersect both states. His current practice focuses on civil litigation and related transactional work in those jurisdictions.
