What Our Clients Are Saying

★★★★★ 5.0 75+ reviews

Every quote below is from a real client review on Marker Law's Google Business Profile — in their own words.

"If you have a workman's comp case (OR ANY INJURY CASE), please do not hesitate to use this law firm. I suffered a pretty nasty slip and fall and required tons of physical therapy and surgery. The settlement at the end of the case was beyond what I expected — they went above and beyond for me!"

— Mitchell Nelson · Workers' Comp Client

"Jayson Marker was great in handling my workers comp case. He was honest and upfront with me from the moment I stepped in his office. He made me feel at ease through the entire process and he did exactly what he said he would do. His paralegal is great as well."

— Joyce Ende · Workers' Comp Client

"Great experience from beginning to end. Jason and his assistants answered EVERY single call I made, even when I thought I was being a pest. I NEVER had a disability payment not come on time in 4 years. If I could give 100 stars I would."

— Michael Garvin · Workers' Comp Client

"Jason and his team were an absolute pleasure to work with. My father was injured in a work-related accident, and since English is his second language, I helped him find legal representation. My father never felt a language barrier and had full confidence in the firm."

— Monika O'Brien · Polish-Speaking Family

"I had a great experience working with Jason Marker on my workers' compensation case. He helped me get my case approved and made the entire process much easier to handle. Jason was professional, knowledgeable, and always kept me updated."

— Jigar Ajmeri · Workers' Comp Client

"My case was a difficult one — depression and anxiety related, which I found was hard to get anyone to take. Then I met these folks at Marker Law and they handled everything, never doubted my issues or concerns and never judged. They did not give up even though there was not much financially in it for them."

— Tom Terrell · Personal Injury Client

"Jason and his staff truly went above and beyond for me throughout my case. They treated me with respect, kept me informed every step of the way, and fought hard to get the best outcome possible."

— Tom · Personal Injury Client

"Jason is truly a great attorney. Very knowledgeable, professional and thorough. Jason and his team of paralegals are also very trustworthy and informative."

— Gino Fiore · Marker Law Client

"I have known Jason and Marisol for years and twice they have represented me on 2 claims. I was very satisfied with the outcome for both claims. I have referred them as well."

— Tim Krejci · Repeat Client

Common Questions

What Injured People Ask Us

Straightforward answers to the questions we hear most often.

Marker Law works on a contingency fee basis. You pay nothing unless we win your case. No upfront costs, no hourly fees, no retainer. If there is no recovery, there is no fee.
A Marker Law attorney — not a call center. Our attorneys handle your case directly and answer calls personally. You will not be passed off or kept in the dark — that is how Marker Law was built from the beginning.
Most personal injury cases in Illinois have a two-year statute of limitations. Workers' compensation claims generally must be filed within three years. Contact us immediately after an injury — waiting too long can permanently bar your right to compensation.
Jason spent years as an insurance defense attorney before switching to plaintiff work. He knows exactly how carriers evaluate claims and where they cut corners. Combined with 25+ years of Naperville courtroom experience, that inside knowledge produces better outcomes for clients than a large impersonal firm can match. And we care about each client. Some firms say that, we prove it. Our attorneys personally handle each case, and treat you like family.
Yes. We represent clients throughout Chicagoland including DuPage, Will, Cook, Kane, and Kendall Counties. If you cannot travel, we will come to you.
First, call the police if you were in a motor vehicle accident, or notify your employer immediately if you have a workers' compensation case. Seek medical attention. Document everything you can — photos, witness names, and any incident reports. Do not give a recorded statement to an insurance company before speaking to an attorney. Then call or text Marker Law at 331-INJURED for a free consultation.
