I needed a lawyer with a child custody case that I was not expecting. Thankfully I contacted Williams Law Office, I spoke with Terri Williams, she immediately reassured me that everything would be fine, and she would represent me. She was extremely professional, knowledgeable, and genuinely cared about her clients. Terri always stayed in contact with me providing any updates that came her way, this also gave me reassurance she was on top of everything involving my custody case. Terri was always early for hearings, meetings, and anything else that involved my case. Terri never missed a beat, and I mean EVER! If you want a lawyer that will go above and beyond for you Terri Williams is hands down without hesitation the individual you want representing, you. I can’t thank Williams Law Office enough for everything you have done for me and my sons. You truly are the best Terri!
