About David John
David John Kozlowski trained for law in New York. He earned his J.D. from St. John's University School of Law in 2006 after beginning his studies in 2002. The law school years left him with classroom experience and an early entrée into the federal bankruptcy courts through a post-graduate clerkship.
In 2006 he served as a law clerk to Hon. John C. Ninfo, II at the United States Bankruptcy Court for the Western District of New York. That year shaped his view of courtroom procedure and the pace of federal practice. The clerkship placed him inside case management, opinion drafting and the calendar of a busy bankruptcy bench.
After the clerkship he moved into private practice. In 2008 he joined Arent Fox LLP as a lawyer. His time there covered a range of matters in federal and state forums. The work demanded familiarity with litigation practice and federal court rules.
Kozlowski joined Morrison Cohen LLP in 2015. He has been listed as counsel in that firm’s roster since then. At Morrison Cohen he continued to operate in both trial courts and appellate settings. The record of court admissions reflects that pattern of practice.
He holds admissions across several jurisdictions. Those include the State of New York and the State of Connecticut, the United States Supreme Court, the United States Court of Appeals for the Second Circuit, and multiple federal district courts: the Southern and Eastern Districts of New York, the Northern and Western Districts of New York, and the District of Connecticut. That range allows him to appear in both state and federal matters and to argue before appellate panels when necessary.
Colleagues describe Kozlowski as steady in court and attentive in preparation. He has moved between clerkship work and firm practice, bringing procedural knowledge from the bench into his advocacy for clients. His career path reflects a steady progression from federal clerkship to private firm litigation.
He maintains an office at Morrison Cohen LLP and remains active in cases that require admission in the federal and state courts listed above. He currently practices at Morrison Cohen LLP, handling matters in federal and state courts.
