A Solutions-Oriented Approach To Fighting Criminal Charges
Any San Diego criminal defense lawyer can tell you about the challenges of your case, and many will dwell on them to keep you in fear. However, finding the challenges is not the goal. Overcoming them is. That is what we do.
Rather than dwelling on all the obstacles in your path, at The Law Offices of Mark Deniz APLC we focus on what we can do to overcome them. Our solutions-oriented approach to criminal defense cases means we take an immediate, proactive approach. The best defense is a good offense, after all.
We will not wait until hearing dates or until the prosecutor offers a plea bargain before taking action on your case. This is reactive and ineffective. When you choose our law firm, Mr. Deniz and the rest of our team will immediately begin reviewing the facts of your case to identify any weaknesses that can be used against the prosecution.
We defend against all criminal charges throughout San Diego County and beyond, including drunk driving, prostitution and solicitation, and domestic violence.
Client Testimonials
“I had a DUI charge with a high blood alcohol level. I wanted trial unless there was a situation that worked for me. Mark kept me informed of every step along the way. We pushed for trial. After several hearings and two days before trial the DA calls us with an offer I could not refuse. Mark was ready for trial and I only took the offer because it was that good. Our defense was ready for trial. I felt that he was always one step ahead. You cannot go wrong with him.”
– Former DUI client
“I was lucky to find Mark. I was scared about losing my job from this. Mark resolved the matter without me losing my job or too much skin off my back. He always communicated with me and let me know I was a priority. I hope never to be in a bind again, but if I am I am calling him.”
– Former client
“I was accused on taking items from a popular department store. They say I took expensive items so the dollar amount was high. The prosecutor charged burglary and theft. Mr. Deniz met with us and gathered character letters from people who know me. He met with prosecutors and told them about me. He got me started before the meeting with volunteer work. By the second hearing they were willing to dismiss the case in a few months. I knew I made a mistake and took responsibility for it. However, Mr. Deniz ensured the event would not harm her down the road. He was great.”
