About Us My name is Thomas C. Nivison. I have been practicing law for more than 25 years, and since 1990, have focused a large portion of my practice on workers' compensation. My goal as a Tacoma, Pierce County workers? compensation attorney is to help any individual who is struggling against insurmountable opponents such as insurance companies. Organizations like these use their power, money and resources to unjustly minimize the compensation that my clients deserve. Call 253-756-9656.
