Federal Magistrate Judge Thomas G. Wilson

“Mr. O’Brien is a very excellent, skilled, experienced lawyer. If you want to go to trial, he’ll go to trial, and guess what, he’s a very competitive lawyer, he wants to win. I can’t think of anybody who could do a better job, whether you want a trial or not. I mean, there’s no one I could think of that would do a better job than Mr. O’Brien.”

Tampa Division

“Mr. O’Brien, Mr. Jackson, come forward. Mr. Jackson, the jury has found that you are not guilty on both charges which you were indicted on.

Your attorney did an excellent job in the case and the jury’s verdict will become the record of The Court.”

Whether your case is in federal court or state court, you need the lawyers of O'Brien Hatfield, PA to protect your rights and fight back against prosecutors.

The role of a criminal defense attorney is to provide legal representation to individuals charged with crimes. These crimes can range from drug trafficking and white-collar crimes to murder and sex crimes. The stakes are high, as a conviction can result in lengthy prison sentences, hefty fines, and a criminal record that can follow an individual for the rest of his or her life.

One of the key arguments in favor of hiring O'Brien Hatfield, PA for your federal criminal defense is the importance of protecting the rights of the accused. The Constitution guarantees the right to a fair trial, which includes the right to legal representation. Without skilled attorneys like Mr. O’Brien and Ms. Hatfield, a criminal defendant may not fully understand their rights or the legal process, which can lead to an unfair trial and an unfair result.

White collar crime is a term used to describe non-violent crimes committed by individuals in positions of power or trust, typically in the business or financial sectors. These crimes can include fraud, embezzlement, insider trading, and money laundering, among others. When accused of such crimes, individuals seek the white collar criminal defense services of Mr. O’Brien to represent them in federal criminal court.

Mr. O’Brien’s role is to protect the rights of his clients and ensure they receive a fair trial. This can involve challenging the evidence presented by the prosecution, negotiating plea deals, and presenting a strong defense case. In many cases, wherein trial is not the best option, Mr. O’Brien will work to mitigate the potential consequences of a conviction, such as fines, restitution, and most importantly imprisonment.

One of the key arguments in favor of retaining O'Brien Hatfield, PA is that everyone is entitled to a fair trial, regardless of the nature of the crime they are accused of committing.

Client Testimonials

There is absolutely nothing that I can do that would be enough to thank Mark for literally saving my life. As we walked outside of the courthouse, my father in law was so happy and told Mark that, “I have to change your name in my cell phone to JC or Jesus Christ, because you just saved a life, in fact, you just saved the lives of an entire family!” My family and I are so impressed with Mark’s professionalism, demeanor and energy from that first scary day we met in a federal courthouse in Orlando, Florida to the amazing last day we hugged him goodbye standing outside a federal courthouse in Brunswick, Georgia. Thank you Mark for giving me back my life and making it possible for me to have a future!

Andrew Jackson

In taking my side, and standing by me with enthusiasm, and protecting my wife and child from myself, you’ve done me as great a service as anyone else ever has, even on the battlefield. I know I may never have the opportunity to repay you directly. So the best I can promise you, is that I will move forward as a man, citizen, Marine and father deserving of the service you’ve done me. I will not disgrace it by squandering this second chance.Again, thank you. You saved my life.
