Here are just a few things that past clients and defense attorneys have said about Mr. Siporin’s litigation skills:

“Hiring Mat was the best decision I ever made.  I sustained a concussion and developed terrible residual problems that did not go away. Initially, I hired a lawyer that did not seem to care about me.  Mat was the exact opposite.  Mat was there for me and believed in me during a very difficult time in my life.  His empathy showed by how hard he worked on my case and how he constantly kept me up-to-date on what was gong on with my case.”

“Mat has passion.  He is a highly skilled advocate for his clients.  I was a defense attorney that tried a case against Mat in Lake County.  During the jury trial, Mat spoke with such conviction that it was clear he truly believed in what he was saying.  His passion clearly swayed the jury and he obtained a great verdict for his client in a very difficult case.”
In recognition of his outstanding legal work, Mr. Siporin was named as an Elite Lawyer by his peers.  Since 2017, he has been recognized as an Illinois Super Lawyer and was selected as a “Rising Star” by Super Lawyers from 2012 through 2016.  Mr. Siporin was also awarded the Trial Lawyer’s Excellence Award in 2014 by the Jury Verdict Reporter. And named to the Law Bulletin’s 2014 “Top 40 Under 40” attorney list, which is bestowed upon less than 1% of the attorney’s practicing in Illinois.

While he was an undergraduate student at Tulane University, Mr. Siporin was admitted to study at the prestigious London School of Economics.  After graduated with Honors from Tulane University, Mr. Siporin earned his law degree from DePaul University College of Law.  As a law school student, Mr. Siporin was named the Editor-in-Chief of a major law journal.  Since that time, Mr. Siporin has been an active member in the Illinois Trial Lawyer’s Association, the American Association for Justice and the Decalogue Society.  He has spoken at numerous legal seminars on various topics, such as “Disclosing and Deposing Expert Witnesses in Complex Injury Cases” and “Pleading and Proving Negligent Entrustment Cases”.
