About David
David Gerszewski combines technical training and legal training in a practice that spans tax and federal appellate work. He earned a Juris Doctor from Arizona State University in 2013. Before law school he completed a Master of Science in Decision and Information Systems at Arizona State and a Bachelor of Science in Decision Sciences at the University of Denver. Those degrees inform how he approaches complex regulatory and evidentiary issues.
After law school, Gerszewski built a multi-jurisdictional practice. He is admitted to practice in Arizona, Colorado, Minnesota and North Dakota, and he is credentialed to appear before the United States Tax Court. He also holds admissions to several federal courts of appeal, including the Eighth, Ninth and Tenth Circuits. That mix of state and federal access shapes the types of matters he handles and the strategies he develops for clients.
Gerszewski’s background in decision sciences and information systems shows up in case work that requires detailed document review and methodical analysis. He often works on matters where numerical evidence and procedural precision matter. His training leads him to break problems into discrete steps, evaluate competing data sets and test assumptions before advancing legal arguments.
He has practiced at Citadel Law Office, where his work has involved both trial-level filings and appellate briefs. His admissions to multiple state bars and federal courts allow him to coordinate filings across jurisdictions when clients face parallel proceedings. That practical flexibility gives clients an option to pursue matters in administrative, trial and appellate forums as circumstances require.
Colleagues describe Gerszewski as methodical in preparation and careful in court presentation. He tends to favor clear, concise filings that foreground the critical legal and factual points. He also spends time preparing witnesses and preparing technical materials for judges who must weigh complex factual records.
Outside court papers, Gerszewski draws on his technical training to manage teams handling discovery and document organization. He is familiar with processes for reviewing large data sets and for structuring information so it is usable in litigation and administrative proceedings. He balances that analytical work with courtroom practice, moving between written advocacy and oral argument as needed.
He now practices at Citadel Law Office, handling tax and appellate matters across the jurisdictions where he is admitted.
