Excellent Experience!!!!
I had the privilege to work with Kaitlin on my case and she was able to reduce the charges from a misdemeanor due to driving on a suspended license to driving without a license. She was also able to get my other citation for turning on a red light dismissed. I was extremely stressed about this case since I was only days away from getting my license back before this happened and I am pursuing a career and she helped out tremendously. I thank her and Grieve Law for standing by me through this case. If I ever need a lawyer in the future, Grieve Law will be the only Law Firm I contact.
