  • "The absolute best attorney I have ever dealt with! Mr. Cornelius represented me on two issues and in both he was superb. I was extremely impressed with his professionalism and excellence in preparing for my trial when I was charged in a false domestic battery case. Not only did he excel in the courtroom but he was also very informative and comforting to me when I was at my lowest point. I shall never forget him. His knowledge of the law and wise application of that knowledge was very impressive. He also referred me to an excellent divorce attorney. Mr. Cornelius is the first name out of my mouth when advising friends who find themselves in need of excellent representation. Because of him my trial was over in 10 minutes, was found not guilty and I got on with my life, and for that I am eternally grateful. Mr. Cornelius also worked and succeeded on having my arrest record expunged. Thank you Mr. Cornelius."


  • "I was falsely accused of resisting arrest and assault on a peace officer. Vincent heard my story and gave me the confidence to know that he could win my case. He also stated that when it came to going to trial, he was the best. I feared because it was my word against the police. He advised me on the penalties of my crimes but assured me that he would "eat them up" on cross examination. He also told me that it would be in my best interest to go with a bench trial which turned out to be the right thing to do. His knowledge and experience, along with his hard work and wit was incomparable. I knew within ten minutes of him speaking in court that I would be acquitted. I was recommended Vincent by two close friends. The fact that these reputable sources suggested the same lawyer was astonishing. I called a few other lawyers still. But after the interviews and prayer, Vincent Cornelius was my choice. I would recommend Vincent to anyone for any defense!"


  • "Mr. Cornelius did an outstanding job presenting my case. At the beginning he discussed with me the practical application of the law toward my case and outline of how to go forward. From there Vince worked with me to insure the best possible outcome. I am grateful to Vince for his knowledge of the legal system and his advise both personally and professionally."
