LeRoy Costner is a Death Penalty Certified and experienced trial lawyer. LeRoy Costner understands when you start something, you must finish it. LeRoy has done it all – farmed cotton fields in Mississippi, and orange groves in Polk County. He had to work full time to put himself through college at Valencia Community College and Florida Southern University. During school, he worked at Universal Studios and a five star Orlando hotel as a concierge, where he learned the “fine art” of service. He then graduated from Barry University School of Law where he won the prestigious Lion of Justice award from the Florida Bar Standing Committee on Professionalism. During his final semester of law school, he worked at the Orange County State Attorney’s Office as a Certified Legal Intern prosecuting 1st and 2nd-degree misdemeanors.

After graduating from law school, he took a job with the Monroe County State Attorney’s Office in Key West, Florida. Over the next five years, he prosecuted thousands of criminal cases. As an Assistant State Attorney, he was a special prosecutor for DUI cases, receiving the same training that law enforcement officers undergo, as well specialized training in prosecution. Before taking on the additional responsibilities of prosecuting crimes of violence, LeRoy was selected to train incoming DUI prosecutors. He then went on to prosecute numerous violent crimes for the Government and was often chosen by his bosses to prosecute conflict cases in other counties which is an honor for a prosecutor.

When LeRoy goes to work for you –here is some of what you can expect – he will diplomatically negotiate with the opposing side so that he can keep the lines of communication open and get the best results for you; he will methodically check the accuracy of your case for all possible defenses. He will maintain communication with you at every turn, and he WILL fight for you if it comes down to a jury trial.

Hard work. That is what Leroy Costner will provide for his clients.

I ran into a little trouble and as it was my first time I was very worried about what to do and where to go. As soon as I contacted umansky law I was immediately relieved of all anxiety that I had about the situation. LeRoy handled my entire case and did a excellent job getting me the best case scenario out of my situation. Billie Guertin was a huge help as well with her rapid response to any questions and sending friendly reminders/checkups about my situation. I feel like I have made a long standing relationship with a legal team if I ever need one. I HIGHLY recommend Umansky Law to anyone seeking a GREAT attorney and AMAZING legal aid. You won’t be disappointed.

LeRoy E Costner
This attorney personally responded to my call today, 2-24-16. In an unrushed, respectful and efficient manner, he provided up-to-date information which allowed me to make an educated decision on whether to fight the notice of red-light camera violation I received in Winter Park, FL. I could tell he clearly deals with this issue currently and on a regular basis, is knowledgeable of the current status of the case law as well as how the hearing officers are currently presiding over these cases. After my conversation with Mr. Costner, I felt respected and empowered even though the current status of how the law is being applied makes it unlikely I would be able to successfully vindicate my rights in traffic court in this case. Should I need an attorney in this practice area in the future I will definitely call Mr. Leroy.

That was Easy! Kind of like the "Easy Button" from those Staples commercials
Outstanding Lawyer! He got my bogus red light camera ticket thrown out. If you are a victim of Red Light Cameras, call Leroy! Stand up for your rights!

He Helped Me Out!
Mr. Costner helped me with a legal issue that could have cost me hundreds of dollars. He got my case dismissed and kept me informed every step of the way. He was a wonderful attorney and a pleasure to work with.
