I take great pride in making sure I place my client's interest before my own. This philosophy includes keeping a low profile. If I am always in the newspaper or on television in an attempt to get "face time" and publicity it means that you are getting publicity. In the area of criminal defense, the less publicity you get, the less damage you will receive to your reputation. Quiet, effective and discreet representation is my goal. My clients have appreciated this approach and it is my promise to represent you aggressively, discreetly and effectively.

Best Lawyer I've ever used, EXCELLENT JOB!
Greg is very professional, he always kept me informed and aware of all options in my appeals case. He got exactly the results that I wanted in my appeals case and did it with ease with a difficult judge. When I started my appeals case, it was an uphill battle but Greg was amazing. I had complete trust in him from day one. He was completely prepared for every court date. If you need an excellent lawyer, call Greg. I have unfortunately used many lawyers in the past years but finally found a lawyer that gets the job done! I can't say enough good things about Greg... Thank you Greg!!

Attorney Petit got my son out of a real jam.
Attorney Greg Petit represented my son when he got in trouble at school for a fight he was involved in. I thought that my son was going to be expelled and I had no idea where to turn or what to do. But Attorney Petit really helped to walk me and my son out of this situation with nothing more than a few days suspention. I would gladly recomend this wonderful law firm and Attorney to anyone who needs help.

Outstanding Lawyer
I was facing a very challenging situation. Greg put me at ease from the first time I talked to him. I felt he really cared about me and my family, and he was always available when I needed him. He clearly explains the process and the strategies he is using and is patient. I'm so happy I had him in my corner. The judge was even impressed with him. I heard the judge compliment him on his thoroughness and level of preparation. I'm sure that doesn't happen to most lawyers. I can never thank him enough.

Great Job
We had no idea where to turn or what to do and by the grace of god ended up contacting Greg. He has been very helpful so far and I appreciate his professionalism and willing to work hard. There will be a long road ahead, but I believe Greg will work hard for us.

He exceeded my expectations!
Attorney Petit kept me informed on the progress of my case, was extremely professional, and incredibly knowledgeable. He immediately jumped on every opportunity he had to help my case & created new opportunities too. He truly faught for me and my case concluded exactly how I wanted it to. He also looks out for his clients financially - he has a low retainer fee & returns any of the remaining balance after the case concludes. He also sends you a monthly detailed statement showing exactly how the fees are being used. I will recommend Attorney Petit to everyone!

DWI Success
When I was charged with drunk driving last year I was terrified that I would lose my license and have to pay a huge fine but thanks to Petit and Dommershausen Law Office I got off with only a small fine and two points on my license. I would strongly recommend this lawyer.

Wonderful attorney!!
When I was in a very bad place and facing jailtime, Mr. Petit was there to help. He is always very professional. I felt I could always go to him with my questions and concerns. He isn't like many attorneys i've dealt with in the past, that you can never get ahold of! He always responded to me quickly and made me feel better about the situation, and he got me great results!! If you're looking for a great attorney that will fight for you, call him!

Finally, a lawyer that's also a REAL PERSON, not just another suit!
Greg made it easy for me to work through wills for my wife and myself and also helped us with power of attorney documents. We were treated with respect and could tell Greg cared about our situation. It's nice to be able to rely on an attorney who is genuine, honest, and a real person. Thanks, Greg!

Great Lawyer
I was extremely satisfied with the services the Greg provided in regards to my car accident case. Greg always had my best interests at heart and he was informative throughout the whole process. Greg always made sure that all of my questions were answered and constantly reassured me that I could contact him at any time if anything else came up in regards to the lawsuit.
