Jeanette was amazingly informational and helped me with my crisis I was going through when I was going through alot. I was not sure how to go about my situation with my partner that was involving the police and wanted a piece of mind and legal advice and called Jeanette and she provided me with great advice and legal knowledge that both protected me and my rights and put my mind at ease so I could feel a sense of control with the situation. It all turned out well and thanks to her i was able to go aboit things in a calm and smart way so I could enjoy my freedom ( because we all know how a few words could leader to trouble) i was very confident talking to the deputies and my partner regarding the situation and highly recommend her for any legal advice and or advice or questions you may have if you are worried or would like some insight on the situation your in.

Best attorneys I could have gone to honestly. They got my case dropped in about a week, and everything went very smooth. The staff is extremely nice and professional. If you get in some trouble, go to them they will get it done!

HIGHLY RECOMMEND. I have a fairly lengthy record and I was falsely advised of impersonating a police officer. Jeanette contacted me immediately and was like a pitbull beginning to end. My attorney, Sheryl, was a very quiet BEAST. Polite, polished, focused and no nonsense. She didn’t beat around the bush but she did her job and O’Brien Hatfield came through helping me walk out a free man today!
As someone who has done a fair share of time and been in those terrifying courtrooms, this law firm demonstrated why it’s important to have a great lawyer and team representing you!

I cannot express enough gratitude for the exceptional service I received from my attorney, Mark and his team (Jeanette and Aaron). From the very beginning, they demonstrated the highest level of professionalism, integrity, and dedication. Every question I had—no matter how big or small—was met with a prompt, thoughtful response that made me feel heard, respected, and supported.
What stood out most was their unwavering commitment to putting the client first. I never felt like just another case; I felt like a person whose concerns truly mattered. Their ability to navigate complex issues with clarity and compassion gave me peace of mind during a very difficult time.
Thank you for being a steady hand when I needed it most. I would recommend this firm to anyone seeking not just legal expertise, but genuine care and commitment.

Mark and his team came into our lives during one of the most difficult and painful chapters our family has ever faced.
Our oldest son was dealing with serious federal charges, and to make matters worse, his second court-appointed attorney had just informed us he would no longer be representing him. In a state of desperation, we reached out to several federal defense attorneys—and while a few responded, Mark stood out immediately.
From our very first conversation, my wife and I knew we had found the right person to help our son. Mark was honest, clear, and direct—but what truly set him apart was the genuine compassion and empathy he and his team showed our entire family.
Despite living over a thousand miles from Mark’s office, we never once felt distant or disconnected. He and his team were in constant communication with us, often speaking daily as we prepared for our son’s final court appearance. They never made us feel like just another case. They stood beside us every step of the way.
If you’re facing your own dark and uncertain moment, and you need someone who will fight for you with both heart and skill—Mark is the attorney you want in your corner
