I was in an accident that resulted in getting whiplash and a concussion. I contacted Phoenix Accident and Injury Law Firm that day. Everyone was helpful (Rhea, Karissa, and Jeff) from the very beginning to the very end. They sent me to a physical therapy location that was pretty far away but the doctor and physical therapist were very kind so I did make the trek. They handled all aspects of my case in a timely manner and answered all my questions. They got the max amount possible, and from that, paid the medical bills and took their fair cut. I would not hesitate to recommend them to family or friends.

I would give ten stars if I could. This law firm is about as professional and friendly as it gets!! They stayed in constant contact with me and answered every question I had. I got a settlement that was higher than I expected and will definitely use this law firm again. I highly recommend hiring them to handle your legal issues!!

What can I say about the Thompson Law Firm? They are AMAZING!! It’s never fun when you need an accident lawyer because you are pretty much in a bad place. Shane and the staff have been wonderful, kept me informed at every step of this process. I would recommend Thompson Law Firm to anyone, in fact, I have referred several friends already!! Thank you Thompson Law Firm for everything you did for me!!!

These guys were absolutely amazing. They were very clear with me about what I needed to do on my end and I saw fast results. I just recommended them to a friend a week ago and he also dealt with my mother's case. I wouldn't see anyone else.
