Mark’s Clients Say

Orlando SeoaneClaims Examiner, Sedgwick

Mark Thomas and Kegel Tobin and Truce in its entirety are one of my favorite firms to work with as a claims examiner. When I contact their office the receptionist always quickly answers my calls and transfers directly to the handling Attorney. This helps me save a lot of time and obtain the information needed to document my file. The Attorneys at the firm always provide a very clear and concise recommendation on case handling. As a claims examiner, I always visit the firm’s website to obtain information on new case law and changes in the worker's compensation system. The firm is a great resource to all claims handling staff in California.

Mark is highly dedicated, through and very involved in his cases. I would highly recommend Mark if you are looking for someone who looks down every avenue and provides extremely detailed and extensive work above and beyond the average attorney.
