I had Mark Hammer as my attorney and was very pleased with the outcome of my case. He is a caring individual that took my case very seriously and got the best outcome for me. I will always be extremely grateful for his help and time.

Just reached out to this law firm found them on google. I reached out for legal counsel and the representative I spoke w was Amy and she was extremely rude! She over talked me several times! She talked over me and hung up on me as I’m seeking legal counsel! I called back and spoke w Maria much more pleasant! Not sure if I’ll stick w them but I most definitely wanted anyone seeking counsel to be aware of the type of customer service representatives representing this law firm!
