Best of the best!
My husband had the most complicated X felony case ever. We called a lot of attorneys but no one was able to help us. Michael Petro was the only one who agreed on to work on that case and he did awesome job. He was able to vacate all charges like my husband never ever had anything on his records. It was mission impossible, but we believed in him and he didn’t disappoint us. My husband and I are the luckiest family due to attorney M.Petro. Would highly recommend him! The price that he charged us was very reasonable for the job that he did. He is the only one that would do his best to help you in any situation no matter how hard it is.

Great job! Highly recommended!
I was in trouble with the Illinois State Police for DUI. Mr. Petro put on my trial and won. The Judge really paid attention to everything he said. He was in control of the whole thing. I would refer anyone in trouble to use Mr. Petro.

Mr. Petro Gets Results
I unfortunately got into some very serious trouble back in 2010 that led to my name being on the FBI website and me facing 44 years in prison. I cannot pretend as if I wasn't nervous but Mr. Petro definitely came through for me in big ways. He is an excellent attorney whose professionalism and personable demeanor is why I would recommend him to anyone in need. He was there for me when I needed him most and never gave me the impression that I was just another client. When my family had issues bailing me out, they called him at 1 in the morning and he answered fully prepared to help. He made sure i didnt have to serve that time in prison and I am forever grateful for that. I can sit here and tell a million reasons why you should put your trust in the guy, however, all you need to know is that when your situation is bleak and you need an attorney who cares and gets REAL results, Mike Petro is your guy.

Mr. Petro saved the day.
On Sunday, I was returning to Miami after a cruise with my fiancée. Out of nowhere, Customs arrested my fiancée allegedly for a warrant from Indiana. Out of nowhere, my fiancée was locked up without bond in the Miami jail. Mr. Petro worked non-stop to get my fiancee' out of the Miami jail. He worked with prosecutors in Miami and Indiana to correct this mistake. Today, my fiancée was released. I can not tell you how grateful I am for Mr. Petro's efforts. HIs experience and persistence is incredible. I would recommend him to anyone that needs a top notch attorney. Thank you Mr. Petro!

Michael J. Petro was there to save the day.
Yesterday, I was arrested for allegedly delivering a pound of marijuana to another guy. I was at the police station for over 24 hours. Fortunately, my brother knew attorney Petro. Out of nowhere, he arrived at the station and got down to business. I think his presence was very intimidating to the police because of his reputation. Two hours later, I was released without being charged and I got my car back. This is such an incredible relief. Thank you Michael J. Petro!

Mr. Petro helps so much.
Being charged with a federal case is so hard. There are so many rules and procedures. Having Mr. Petro on my side made the difference. He has been doing this stuff so long that there isn't one question you could ask him that he doesn't know the answer too. With all this knowledge of the system and the judges and the laws, making the right choices is easy. I appreciate this man and this lawyer. If you have a federal case, call Mr. Petro, he is the best!

Mr. Petro was on fire!
Yesterday, Attorney Petro was on fire. I can only say that his cross of the two State's witnesses was like fireworks. He relentlessly cross examined the State's main witness. The witness caved in. The truth came out. And the Judge found me Not Guilty. Mr. Petro was professional and timely. I would recommend him to anyone that is in trouble with the law.

Michael Helped Me and My Family
Michael Petro saved me from jail. I was federal charged for opening a bank account that was used for fraud. Michael prepared the case for trial. The day before the trial, the prosecutor reduced my case to a misdemeanor federal charge and I got probation. At the sentencing, Michael brought my whole family and kids to convince the Judge. Use Mr. Petro if you have a federal case.

Michael J. Petro Beat Two Cases for Me!
Michael J. Petro represented me two times. Both cased went to trial. Both cases I won due to the great lawyering of Michael J. Petro. I would hate to think of my life today had the outcome of either case been different. Hire Michael J. Petro with confidence.

Mr. Petro did excellent work!
Mr. Petro did excellent work. He dealt with me and my mother. He was always timely and professional. At trial, he cross examined two police officers with confidence and persistence. The truth finally came out and the Judge found that the police illegally searched my vehicle. I had a lot to lose if I was convicted. Mr. Petro worked hard to get me a good result that keeps me moving forward in life. I would recommend using Mr. Petro. He does a great job!

When I first started looking for a lawyer to represent me, I ran across Michael Petro and quickly called him to inquire information. I agreed to have him represent me, not knowing I'll regret it later. Horrible representation. When I read his reviews online, they were all positive. However, I did not see any of the positive things that were said about him in person. When I observed his authority in the courtroom, I soon realized he did NOT have any. He was completely stepped all over and I knew I made a mistake. $1350 down the drain. Not much progress has been made. On top of it all, I was accused for being on drugs by him? Felt taken advantage of and disrespected. Never will I put my trust in someone who ends up being a complete wack lawyer.

Response from Michael Petro August 27, 2014
I will start by stating that I value my clients and their confidentiality. So without compromising yours, I will only state that your lifestyle of drug use and prostitution is the cause of all your disappointment. At all times as your lawyer, I worked hard to alleviate the mess that you had created for yourself. I will start by stating that by the time you hired me, the Department of Homeland Security had placed an ankle bracelet on your leg to monitor your whereabouts. The first difficulty in representing your case was that the outcome of your case could lead to your removal from the United States. The second difficulty in your case was that at the time you retained me, a warrant had already been lodged against you in Cook County for missing court. At the first court date as your lawyer, the Judge refused to reduce your bond because of your criminal background, and your failure to notify the court of your whereabouts. To keep you from being placed in the Cook County Jail, I tracked down your business associate to get money for your bond. I then spent my time posting his money for your bond because your business associate refused to go in the court house. Because of the complications caused by the ankle bracelet, I waited for you to be released from the court house lock up. I was also kind enough to provide you with transportation to your hotel. At the second court hearing, you appeared two hours late for your trial. Because you were so late, the police officer witnesses were released by the Judge. In order to insure that another warrant was not placed for your arrest, I waited until you arrived at court. When you arrived, your behavior was erratic including crying at one moment to laughing the next. You were also extremely paranoid. Based on my experience, I concluded that you were severely under the influence of drugs. Despite these limitations, I worked hard to first get the prosecutor to drop the charges. I also had an issues conference with the Judge and the prosecutor to try an get a resolution to your charges that would not get you deported. Because of your criminal background and the serious nature of the charges, no resolution was able to be reached. A new trial date was set. After court, your erratic behavior continued. The new court date caused you lose your temper. In the end, your foul behavior caused me to terminate our attorney client relationship. To conclude, at all times, I represented you with competency and integrity. I am sorry your that your life of drug use and prostitution have caused you to lose your children, face criminal charges and also face being deported from the United States. But to deal with your problems by creating lies about me is a new low. For 26 years, I have worked hard to acquire a reputation for skill, persistence and integrity. I stand by my representation in your case.
