About Jonathan David
Jonathan David Warner moved from sociology and economics into law over the course of a decade. He earned a B.A. in sociology and economics from the State University of New York at Albany in 2007. He then enrolled at Michigan State University College of Law, finishing his J.D. in 2011 and taking substantial coursework in tax law while there.
His early legal training included consecutive summer clerkships on federal benches in upstate New York. In 2009 he served as a summer judicial clerk at the U.S. District Court for the Northern District of New York. The following year he returned to the federal courthouse as a summer judicial clerk at the U.S. Bankruptcy Court for the Northern District of New York. Those seasons in chambers introduced him to both district court litigation and bankruptcy procedure.
Warner is admitted to practice in New York and holds admissions in several federal venues. They include the U.S. District Courts for the Southern and Eastern Districts of New York, the U.S. District Court for the Northern District of New York, and the U.S. Tax Court. He has handled matters that require practice in federal trial courts and tax litigation forums.
He has been active in the local and state bar communities for more than a decade. Warner joined the Capital Region Bankruptcy Bar Association and the New York State Bar Association in 2013. He became a member of the Albany County Bar Association the following year and remains involved in those associations. His memberships reflect an interest in bankruptcy and tax practice as well as in networking among judges and peers in the region.
Colleagues describe Warner’s background as one built on federal court experience early in his career and steady involvement in court-focused bar groups since. His education in sociology and economics provides a broader social and financial perspective that informs how he evaluates cases, while his tax coursework complements litigation experience in tax and bankruptcy contexts.
He maintains a practice that handles matters in federal district courts, the U.S. Tax Court and bankruptcy proceedings. His work continues in New York federal and tax venues as of 2026.
