C. Sei-Hee Arii

When I started my own firm, I knew that its priority would be on helping regular people. My clients include lawyers, doctors, construction workers, landscapers, teachers, students, housekeepers, and soldiers. To me, their occupation is mere window dressing. In my mind, the housekeeper’s work is just as valuable as the doctor’s work. They come to me with a problem and I help them find the best solution.

I firmly believe in the rule of law as one of the hallmarks of democracy, but the law is an imperfect instrument and justice is not a given. I see my role as mitigating the many unfair things that can arise when the blunt instrument of the law is applied to an individual who has unique circumstances. I believe that everyone deserves a second chance and it is my job to protect the average person from the ruthlessness that can sometimes emerge in the courtroom when the law is applied heartlessly.

If you were to talk to the people who know me best, they would say that the way I approach cases are with tenacity, extreme focus – to put it in plainer words, I am like a dog with a bone, I give it my all and I don’t give up – and without bias.
