Press Releases

My secretary used them and said nothing but good things. My initial conversation with them went well and seemed to be pretty straight up, which I can’t say for all lawyers that I have spoken to.

ROSALIE G.Yelp

I was very pleased with my experience with my injury attorney. They are very attentive to the needs of their clients. Top notch professionals and answered all my questions as needed. Would highly recommend to friends and family involved in car accident that resulted in injuries.

As a rule, I don’t give reviews…ever. I am making an exception in this case. I had a motorcycle accident, where I was very lucky to keep my leg…and my life. In my search, for the BEST lawyer…Gallagher & Kennedy was my first stop, of 6 scheduled appointments with potential lawyers that day. It was immediately apparent…I already found my team. During my rehabilitation, including 2 major surgeries, I was consistently updated about the details pertaining to my case. The best way I can describe this legal team is…Taking care of business! They got me a 7 figure settlement…In Less than 1 year…just as I got back on my feet, and walking around again! THANK YOU SOOO MUCH!! If I ever need ANY legal assistance, as long as I live, I already got my team. Just the fact that I am making this review, should tell you, all you need to know. 6 outta 5 Stars!!! You gave me my Dream Life!!
