After having another attorney for 4 months that didn’t do anything he said he would do, I hired Corey. Corey took the bull by the horns and took care of my legal needs in a timely fashion. Very professional, motivated and a knowledgeable lawyer… would definitely recommend him for your legal needs.
"Corey is a tough attorney who will vigorously fight for his clients. I have worked with him on multiple occasions, and there are few attorneys that have Corey's passion and work ethic."
