Notable Cases

Mark A. Simon fights hard for his clients. He’s obtained significant results for individuals throughout Colorado, including one of the largest wins on record for the state.

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 received the benefits that he was entitled

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.
