You have too much to lose to risk getting anything better than the best defense available.

Money Laundering

In recent years, government agencies, such as the FBI, have been placing more emphasis on combating money laundering.

If you are facing charges of money laundering, you need an experienced criminal defense attorney on your side.


If you have been charged with a DUI, our Orlando drunk driving defense attorneys can help. Since 1982, The O’Mara Law Group has stood up for the rights of people throughout Central Florida. We are committed to keeping your record clean, and he is committed to getting you results.

Mortgage Fraud

In recent years, instances of mortgage fraud and appraisal fraud have become more common in Orlando. As a result, the government has become much more active in prosecuting these white-collar crimes, actively pursuing investors, brokers, straw buyers and others involved in mortgage fraud schemes.


One of the most serious accusations an employer can level against an employee is employee theft, known as embezzlement. Embezzlement is a fraud charge that is aggressively prosecuted as a felony, with a conviction possibly resulting in jail time, restitution and irreparable damage to career prospects.

Murder Defense

If you have been arrested and face a murder charge or a homicide charge, you need a law firm who will stand with you and work diligently to protect your life. The O’Mara Law Group is ready to take on your murder defense case.


A successful defense against white-collar crimes, such as fraud, must differ strategically from a defense against other types of criminal charges, such as drug possession or murder. The O’Mara Law Group believes that these cases require a sophisticated legal strategy that is able to match the complexity of the issues involved.

Prescription Drug Charges

With state and federal law enforcement increasingly cracking down on the illegal possession of prescription drugs, it is critical that you have an experienced law firm on your side if you are facing charges of unlawful prescription drug possession. You can rely on the O’Mara Law Group to work diligently to protect your rights.

Healthcare Fraud Defense

These are complex cases that should be handled with hard work and diligent preparation. When you choose Orlando healthcare fraud attorney, Mark O’Mara, to handle your case, the team will make every effort to protect you against the impact of healthcare fraud charges.

Sex Crimes

Sex crime charges are easily the most destructive charges that can be made against anyone. Even when falsely accused, the stigma associated with these charges can damage your reputation, hurt your employment prospects and change relationships forever. If you have been arrested or are under investigation for a sex crime, you need an experienced Orlando sex crimes defense attorney on your side.

Internet Crimes

As times change, so do the crimes that people are accused of. A criminal defense attorney has to stay updated as the law changes to address new crimes and the technology used to commit those crimes. Throughout more than 35 years of practicing law, the O’Mara Law Group has been dedicated to staying on the edge of important legal developments. We have sorted through the most complex criminal matters to get fair and just results for our clients.


Property crimes, such as burglary, automobile theft and shoplifting are among the most common criminal charges. However, common does not mean it is not serious.
