Practice areas
  1. Criminal defense

  2. DUI and DWI

  3. Animal and dog bites
    If you or your child have been bitten or attacked by a dog, a personal injury lawyer experienced in dog bite cases can help you bring a case against the owner for medical bills, mental anguish, and disfigurement.

  4. Car accident
    If you are involved in a car accident, you may benefit from the services of a car accident lawyer, one who knows the dynamics of car crashes and can identify and weigh all the possible factors which may have played a part.

John Leo is a military veteran of both the Marine Corps and the Army.  After 4 years of enlisted service with the Marines, he transitioned to the Army and flew scout/attack (OH-58D) helicopters for 10 years; completing three tours in Afghanistan. John brings his military discipline and work ethic to the practice of law.  

Mr. Leo has focused his practice in criminal law, and specifically fighting to defend the rights of those who have been accused of a crime. Whether you have been accused of drug possession, driving while intoxicated (DWI), assault, theft, or even gang related organized crime; Help Is Here! John Leo will fight to protect your rights if you decide to take your case to trial. John Leo is happy to make the State try and prove their accusations to a jury at trial. When going to trial is not the best option, Mr. Leo will negotiate on your behalf and highlight the good facts to get you the best deal the prosecutors will offer.

If you have been charged with DWI, Possession of Controlled Substance, Theft, Assault, Burglary of a Motor Vehicle, or other crimes, John Leo of Leo & Oginni Trial Lawyers is a criminal defense lawyer you can trust!

*My goal is to provide affordable defense to the people of Harris, Brazoria, Wharton, Galveston, and Fort Bend Counties who have been accused of a crime.  If you are accused of a crime, you should not be at the mercy of the State or have to fight alone.

Very professional, great advice
I was attacked by a loose dog while walking in Hershey Park. All I wanted was for the owner to pay for my bill to see my doctor but they kept putting me off. After I talked to Mr. Leo, he contacted them and explained my position and what I wanted done, along with what he was going to file if we didn't get it settled. After talking to him they agreed to pay my doctor's bill. Thank you sir!

"I have been practicing law for the last twenty years. Any attorney you select needs to fight for you. You need someone who has a history of hard work and dedication to service.
