-Nadine
So, I used to live in The San Bernardino Mountains in SoCal about 15-20 years ago. I now live in TN. I had an opportunity to foster my grandson here. In the process of being approved to be a foster parent, I was fingerprinted and had to consent to a background check. I did this willingly believing with all my heart that I would be cleared. Much to my shock, however, it came back that I had an active warrant in CA for failure to appear on driving without a license. Now, the reason that this shocked me was because…

-Jesus
Dan at Kolacia Law Firm was very timely and punctual in handling my petition for an expungement. He was always professional maintaining an understanding and non-judgmental position while taking the necessary actions to gain a favorable decision from the court. He not only took the necessary actions to submit the appropriate package but also overcame DA's objections and other obstacles. My expungement was approved and now I can finally start fresh and be the best citizen I possibly can and better provide for my family. I do recommend!

I highly recommend Kolacia Law Firm. Attorney Daniel Kolacia helped successfully grant an early termination of probation and dismissal of my DUI.

I recently ran into an unexpected and serious situation legally, and I knew I had to find a serious attorney to represent me, and I found that with Mr. Daniel Kolacia.

-Max
I can’t recommend Daniel Kolacia's law firm enough, and his wonderful assistant. After my DUI charge, I was feeling lost and anxious about what to do next. From the very first meeting, he was not only knowledgeable but also genuinely compassionate, taking the time to explain everything clearly. I followed his instructions to the letter, and I’m so glad I did. Thanks to his expertise and dedication, I got early termination of my probation and even managed to get my record expunged! He was always there to answer my questions and really supported me throughout this challenging time. If you’re…
-Cee
From day one, Dan Kolacia helped ease a level of anxiety I wouldn’t wish on anyone. Walking into this situation, I was stressed, overwhelmed, and constantly worried about the unknown. Dan immediately brought a sense of calm and control. He didn’t just tell me “it’ll be okay” — he explained exactly why. He took the time to walk me through the entire process step by step, clearly laying out how things were likely to unfold and what to expect at every stage. That transparency made all the difference. Knowing the plan, the timeline, and the possible outcomes helped me sleep…
-Chris
Mr. Kolacia is a beyond amazing lawyer. I would give him 100 starts if I could. Being an individual in the medical field who needed an expungement dismissed, it was a very emotional and difficult situation for me but Daniel made me feel confident and well taken care of. He told me very directly what to expect and what I need to do to get the best results for my case. Daniel always made himself available to speak on the phone if I had questions and he is quick to respond to emails. In the end, Daniel successfully was able…
-Zhana
Daniel Kolacia made going through the court system for my DUI an extremely easy going experience. Having to go to court and dealing with judges and the court system, not knowing what my rights are made me feel a bit scared and anxious so having Daniel Kolacia by my side made the whole experience much easier on me. He remained available whenever I had questions, always made sure to contact me with results or any news, he did whatever he could to make this process less stressful for me so I’m happy with my results and he was 100% worth…

-Chris
Where do I begin, I ran into some trouble last year before Thanksgiving and I had consultation from a few other lawyers and let me tell you nothing compared to Dan's team when I first contacted his office. His team was welcoming and provided hope to me at a time I was hopeless. I explained my charges to Dan and he walked me through what I needed to do before we showed up to court. I can't thank Dan enough for what he was able to do for my case. His Knowledge to show up prepared before my court date…
-Ricardo
I had multiple old traffic tickets from California dating back over 20 years that were causing me issues, and I was really worried about how to resolve them after so much time had passed. I hired Daniel Kolacia from Kolacia Law Firm a local California attorney who knows the area and courts inside out. We prepared for what we thought might be a drawn-out court process lasting a month or more. To my amazement, he went in on the very first court date and got everything dismissed completely! His expertise, preparation, and ability to navigate the system efficiently saved me…
-William
Unfortunately I have had the opportunity to work with several attorneys in my life and I have to say, Mr. KOLACIA was an absolute pleasure. He was very clear , to the point, fair and dotted all of the i’s and crossed all of the t’s. He was quick, very dependable and really an unexpected pleasure. If I’m ever in need of an attorney in Southern California again, I feel like I have an attorney I can trust. Very professional and refreshing!
-linda
Daniel Kolacia at the Kolacia Law Firm did exactly what he said he would. Other big name companies would give me the run around and tell me that it couldn't be done. He got my Felony reduced to a misdemeanor. He worked with me through all steps and once I got him everything he requested the court date was set. He appeared in Court for me as I live 2500 miles away and called me to let me know the results. Can't ask for better communication and expertise.I would recommend Daniel Kolacia to anyone needed his services.
-Steve

My son was looking at very serious consequences and through all this he was super encouraging and guided us through to the best outcome ever! His wisdom and experience is excellent! When looking around there are so many options. You won't go wrong calling him. Don't hesitat this will be the best call you make if you need an attorney. The right person makes all the difference when the stakes…
-Patrick
I have always been skeptical of lawyers until I spoke with Daniel Kolacia. With just his introduction he set me at ease and throughout the whole process made me feel more comfortable than I've ever felt dealing with the law. He never gave up on me, and tells me his commitment comes from a higher place of reverence. I am so happy with the outcome that I not only consider him as my lawyer but I consider him as a friend. Thank you Kolacia law for everything that you have done.
-Arthur
Mr. Kolacia defended my case honestly and better than I thought possible. I truly thought I was going to jail. He always advised me logically and with empathy to my personal situation. Always referring to me, with the choice in direction on how to proceed. Regardless of my decision, he defended me vigorously. The outcome of the case was more than fare. Even after the sentencing he still consults with me. Daniel Kolacia did not sugar coat any bad or good news regarding my case. I hope more people get the same professional help that I received.
-Sean

Asked
Questions
Can I still be found guilty of a crime if there isn’t enough evidence against me?
In order to be found guilty of a crime, the prosecutor must prove their case beyond a reasonable doubt. If there isn’t enough evidence to meet this standard, the charges against you may be dropped or you may be acquitted of the charges.
