What
Our Clients Say

This firm was effortless to work with. They were professional, explained everything about the process in detail and were great answering questions. Every step of the way was just as they explained it would be. There were no surprises. I am glad I chose them to represent me. You will be too.

– Carol

Attorney Andrews has been a great Attorney to work with. I have been informed throughout the entire process of everything. Normally, I don’t leave reviews, but I would recommend them to anyone. You are not treated like a case. They explain everything and make sure you understand, and if you don’t understand, they make sure to talk in a way that you do understand. They make sure you are ok with the process as well. I would give them more than 5 stars if I could. Thank you.

– LFL

Attorney Brooke Houston and all of staff at Groth Law Firm were very considerate and showed the upmost compassion. She went above and beyond to help me fight my case, which was a success. Thank you for all of your time, assistance, and dedication.

Lydia Delgado

When I had my first car accident, I didn’t know how to make sure I was taken care of. With the loss of my car and sustaining injuries from it, I called around and got to Jackie from Groth Law, and she gave me the most assurance that they would work fast and thoroughly with my case. From doctor’s visits to physical therapy to surgery, everyone from Groth was there to help me with questions I had and other important documents that I didn’t even know I should be worried about. There are no words to describe how grateful I am for their help during such a difficult and stressful time, I am way better off now than I was before I called them.

– Chao

Thanks again for these great testimonials. We try to do our best for our clients and you know, this just makes us feel great that clients feel this way.
