Notable Cases

The Court concluded that the statement taken by the insurance company was not produced in anticipation for litigation, and the insurance company had to produce it for Mr. Simon.
Ms. Lazar’s injury resulted from an automobile accident caused by Patrick Riggs, for failure to exercise reasonable care. Mr. Riggs admitted during his discovery the existence of a recorded statement in the possession of his insurance company. Mr. Riggs objected and refused to produce the document through a claim of protection of the document as work produced in anticipation of litigation.
Mr. Weidert injured his back, and brought a claim against Chris’ Home for temporary total disability and health care. Chris’ Home denied liability on the grounds that Mr. Weidert was an independent contractor, not an employee and that Mr. Weidert’s condition was caused by a pre-existing condition, not an industrial accident.
Mr. Weidert received the benefits that he was entitled

I had a very bad experience with an attorney many years ago, that after signing his contract, never answered my phone calls, or wanted to see me when I went to his office. I had to fire him, so the injury case adjuster could talk to me. After I did everything myself, the case closed, and the attorney still took his 33% of my settlement. Obviously I was very worried about getting an attorney again. I called a lot of attorneys, and after meeting with Mark Simon, he sounded and looked very honest and professional. I trusted my instincts and went ahead with signing his contract. The best thing about working with Mark Simon, is that 1: He called me back when I left an important message with his secretary, usually within the same day. 2: He is very honest and clear about your options. 3: He gives you expert advice about what NOT to Do or SAY, that will hurt your case. All of these qualities gave me confidence and courage to keep going, even though at work, they were trying to make me quit. I remember one time that he called the adjuster to change the light duty work they were forcing me to do at work. That showed me his dedication to helping me out, and actually working on my case. Now I know what a good attorney can do for me. I recommend to be VERY careful before signing anything, make sure you hire a good attorney. I feel very lucky to have found Mark Simon.

I was in an automobile accident on January 26th, 2023. I was referred to Mr. Simon from a friend. Mr. Simon took care of everything for me. I could then focus on my recovery. I did not have to worry about dealing with insurance company's or any medical bills that came in. This was a huge relief for me. I did not want to be taken advantage of by the person at fault or their insurance company. If i had questions or concerns Mr. Simon would contact me to explain.
I was always given the steps that would be taking place during this process. Once everything was settled I did not have to pay any bills. Mr. Simon took care of it all. Stress free!!
Hopefully, I never have to go through any of this again but if so I would definitely call Mr. Simon to represent me. Great experience.
Special thanks so Nicole. You are truly the best thank you!!

I can’t say enough good things about my experience working with Mark. I had a workman’s comp claim that was initially denied. I had never had to navigate an insurance claim process before and thankfully Mark took on my case and the end result far exceeded any initial expectations I had when I was injured. Mark and his staff were professional, reliable, and at each step of the process things happened exactly as he explained they would.
He also is clearly very skilled at negotiating with insurance company lawyers and got me significantly more than their initial offer. And I got the surgery paid for. Highly, highly recommended.
