About Peter J.
Peter J. Mancini combines legal training with a background in banking and business. He reads closely and writes precisely. Those habits trace back to undergraduate study in English literature and medieval history at the University of Michigan, where he developed a taste for careful analysis and long-form research.
He continued his preparation with a graduate degree in banking from the University of Wisconsin–Madison, studying bank management and the institutions that underlie commercial lending. He later earned an MBA in business management from Eastern Michigan University. Mancini then turned to law and completed a J.D. at Western Michigan University Cooley Law School, concentrating on transactional law. He returned to Cooley for an LL.M. in tax law, awarded in 2020.
Mancini’s early practice blended commercial and regulatory work. His academic background in banking and business informed transactions and compliance matters. Over time his caseload shifted toward tax issues, where the combination of law and advanced tax study has been directly relevant. He is admitted to practice in Michigan and before the U.S. Tax Court.
His transactional training shows in contract drafting, deal structuring and client counseling. He is comfortable handling negotiations and preparing the legal documents that accompany commercial deals. His tax training plays a role in assessing the tax consequences of transactions, in representing clients in tax disputes and in advising on tax-efficient structures.
Colleagues describe his approach as methodical. He favors clear memos and careful planning over flashy rhetoric. That approach suits complex tax matters and bank-related transactions, which often turn on detail and chronology.
Mancini writes and speaks on technical topics for clients and internal audiences, and he has been involved in matters that require coordinating accountants, bankers and counsel. He draws on his background in business and banking when explaining tax positions to nonlawyers.
He is currently of counsel at Great Lakes Law Office, PLLC, where he handles tax controversies, transactional work and regulatory matters. He represents individuals and businesses in state matters and in proceedings before the U.S. Tax Court. His current practice focuses on tax and transactional issues in Michigan and before the Tax Court.
