About Juan
Juan Ooink trained first as an engineer and later as a lawyer. He earned a Bachelor of Science in Mechanical Engineering from Lawrence Technological University in 1996 and a Juris Doctor from DePaul College of Law in 2003. Those two degrees sit at the core of his professional story.
After law school he entered private practice. Records show he became a partner at Giamanco & Ooink in 2007. That role placed him in firm leadership and exposed him to complex client matters across state and federal courts. A decade later he launched his own practice. In 2017 he became the owner of Ooink Law and has run the office since then.
He is admitted to practice in Illinois and is also authorized to appear before the United States Courts of Appeals for the Sixth and Seventh Circuits and the U.S. Supreme Court. Those admissions reflect work that crosses trial and appellate lines and involves both state and federal procedure. His engineering background often informs how he approaches technical details and evidentiary questions in cases.
Colleagues describe him as methodical in court and deliberate in preparation. He has handled courtroom litigation as well as appellate filings, and he has navigated procedural hurdles that arise when cases move from trial courts to higher tribunals. His career path—engineering to law, partner to firm owner—illustrates a steady move toward controlling the litigation process from strategy through written advocacy.
At Ooink Law he manages a small office that serves clients in and beyond Illinois. The practice handles matters that require courtroom presence and appellate briefing, and it often involves federal filings given his admissions to the appellate courts and the Supreme Court. He staffs the office to reflect those needs and directs casework with an emphasis on clear legal writing and orderly trial preparation.
People who seek him out tend to need an attorney who can work across different procedural stages of a dispute and who understands technical subject matter. He currently concentrates his practice on litigation and appellate work through Ooink Law.
