Hi my name is Daniel Villalba & Daniel Kolacia helped me with my DUI situation. I recommend because he’s willing to give his all to help out with your issue. He’s a very nice guy to talk to & work with. Give him a chance to help you he’s worth it. He saved me time in jail and also saved lots of money.

Highly recommend Mr. Kolacia
Mr. Kolacia did an exceptional job at representing us. It was pure professionalism from the start. The communication was bar none. Mr. Kolacia answered all of our questions without hesitation and made us feel comfortable in an uncomfortable situation. We were thrilled to hear of our outcome and had no doubt that Mr. Kolacia would do what he said that he would do. I highly recommend Mr. Kolacia if you are looking for legal consulting or need legal assistance. Troy
