About James D
James D Mitchell transitioned from engineering to law in a career that mixes technical training and courtroom practice. He earned a Bachelor of Science in Mechanical Engineering from the University of Illinois - Urbana-Champaign and later completed a J.D. at Chicago-Kent College of Law, Illinois Institute of Technology. Those two fields shape how he approaches the work that reaches his desk.
He began his legal career at Mulherin, Rehfeldt & Varchetto PC in 2018. There he worked as an associate handling matters that required careful factual development and attention to procedural detail. Those early years were formative. They taught him how to build a file and how to prepare for contested hearings and negotiations.
In 2022 Mitchell joined Lee Sheikh & Haan LLC. He practiced as a lawyer there, taking on matters arising in Illinois courts and administrative settings. Colleagues describe him as methodical in his preparation and clear in courtroom explanations. He has handled discovery, motion practice, and client counseling at different stages of litigation.
His mechanical engineering background remains a practical asset. It informs his review of technical documents and his conversations with expert witnesses and engineers. That grounding helps him identify the questions worth asking and the evidence that matters. It also shapes the way he writes and presents technical issues to judges and opposing counsel.
Mitchell maintains membership in the State Bar of Illinois and is authorized to practice in the state. He has worked on cases that require coordination across teams, including outside consultants and experts. His practice style emphasizes careful fact-gathering, straight-forward legal analysis, and preparation for contested proceedings.
Outside the office he has continued to follow developments in both engineering and law. He keeps current on procedural changes and practical developments that affect trials and administrative hearings in Illinois. He currently practices at Lee Sheikh & Haan LLC in Illinois, where his work focuses on legal matters arising under Illinois law.
