Mr. Cassian's practice focuses on the litigation of civil matters such as personal injury, medical malpractice, commercial litigation and unemployment compensation claims.

Since taking and passing the State Bar Exam in 1994, Mr. Cassian has handled countless litigation matters in Northern Illinois Courthouses. He has conducted jury trials in Cook, Will, Dupage, Kane, Kankakee, Kendall, Winnebago and LaSalle Counties. For the most recent 11 years of his career, he worked for a national law firm based in Illinois. During his time there, he represented one of the largest retailers in the world, represented numerous hospitals, the insureds of several well-known insurance companies and numerous physicians and nurses in the defense of a variety of claims.

"Over the years, I have developed a diverse civil practice. Since 1994, I have concentrated on personal injury, medical malpractice, unemployment compensation and collections work. For over a decade, I represented defendants such as doctors, hospitals and major retail establishments as well as the insureds of many large insurance companies. I have developed an extensive knowledge of what it takes to prepare a claim or case and present it to the insurance company or claim representative that represents the defendant. I have practiced in Cook, Dupage, Will, Kane, Kendall, Lake, LaSalle, Bureau, Champaign, Vermillion, Sangammon, Kankakee and many other Illinois Counties. Not only have I appeared before judges in these counties, I have presented trials to juries in many of these counties. I know what it takes to win the cases that I accept and I keep my clients informed along the way.

I have also performed countless unemployment compensation hearings on behalf of both employees and employers."

It is especially rewarding to help people get through difficult legal situations.  One of my clients gave me a thank you note that reads:

"Dear Mr. Cassian, 

I am so grateful for your help.  It is almost impossible to explain how your kind, positive, straight-forward demeanor reassured me. You didn't make me feel like I was wasting your time - you answered my questions and explained the process and the law so that I felt like a participant and not swept along without support.

You were not condescending, but positive and refreshing to speak with.  Your 'people' skills are a great asset to your knowledge and experience with the law. 

Thank you."
