Press Releases:



“I was wrongfully accused of five criminal misdemeanor counts including two for assault, two for battery and one for false imprisonment. I first contacted and met with Attorney Matthew Wallin at Wallin & Klarich after my arraignment date had already been set. This was my first experience in dealing with the criminal justice system and being in trouble with the law. I was slow to react to the wrongful accusations and did not fully understand what I was about to face. In addition, I was initially confused and fearful of my situation.

From my first meeting with Attorney Matthew Wallin, I immediately felt very comfortable and confident that he was the best attorney to handle my case. Attorney Wallin explained all aspects of my case and answered all my questions. After my first consultation with Attorney Wallin, I finally felt some relief about what I was about to face. I also began to understand the legal process that was to follow. I hired Wallin & Klarich immediately following the first meeting.

From beginning to end, Attorney Wallin was very professional, patient, a terrific listener and an excellent communicator. My correspondence with Attorney Wallin was frequent and he always made time in his busy schedule to discuss my case. He was also very organized and kept me updated every step of the way on my case status.

My case ended up going to a jury trial. I was found not guilty of three counts. The judge dismissed the remaining two counts due to a hung jury. I was particularly impressed with Attorney Wallin’s skills in the courtroom and his ability to strategically plan and execute my defense case. I would recommend any family member or friend to hire Wallin & Klarich to handle any type of criminal case. Attorney Wallin is truly a talented and highly skilled attorney. I feel very fortunate to have found Attorney Wallin to represent my case. I would like to thank Attorney Matthew Wallin and Wallin & Klarich for the successful win of my case.”


“I received that call no parent ever wants to receive early one morning….”Dad can you pick me up? I have been arrested.” After finding out he got caught in a dragnet sting going after johns and not sure what our next step was, I contacted a family friend who’s an attorney. I explained what happened and without hesitation, he told me to immediately contact Wallin & Klarich. We made a phone call that morning and they scheduled the initial consultation. Within the first few minutes of our meeting, we knew we had the right firm. Matt Wallin and his team walked us through every step of the way. They were available, honest and upfront about challenges and what was to come. It was on trial day when I heard other attorneys explaining for the first time things Matt had explained months earlier, it just reaffirmed our decision why we hired Wallin & Klarich. We left that day extremely pleased with the outcome and the way our case was handled. Thank you Matt and Wallin & Klarich for being there to represent and guide us through such a difficult process.”


“After meeting with Lawyer Matt Wallin, he took control of my case and contacted law enforcement and the prosecutor’s office. Attorney Matt Wallin kept me informed and involved in all aspects of the case. Matt Wallin had superior knowledge and experience in the Orange County courthouse my case was pending out of. He is a tremendous person and an outstanding attorney. His efforts are the reason I did not lose my job and future. I would highly recommend him to anyone who is in a legal bind and facing criminal charges in Orange County.”


“My experiences with Wallin & Klarich have been nothing short of wonderful. I was caught in the act of stealing and was arrested and charged with 3 counts of felony commercial burglary – all at the age of 18. I was a star athlete and top student with no previous record whatsoever. You can imagine how terrified I was.

My family and I immediately sought legal counsel and decided on Wallin & Karich. Before I had even arrived for my consultation, the office had gone through my case and expertly matched me with attorney Matt Wallin, who has extensive experience with the same court that I was assigned to. My favorite part about first meeting Matt was that he was not judgmental in any way, shape or form.

He took the time to make absolutely certain that my father and I fully understood the charges and the timeline of the proceedings to come. He was warm and kind, but very professional and reassuringly confident at the same time (quite a rare combination in a lawyer). He answered every single question that my father and I threw at him with a confidence. That told us that he was extremely experienced and knowledgeable in this area of law.

When the court date finally arrived, Matt was on time and looking professional. I observed as he interacted with others in the court and I got the sense that he is a regular in that room and that he is very comfortable in that environment. It was very encouraging. When my case was called, I watched as Matt went to battle for me. He fought for the best possible outcome and that’s exactly what he got for me.

My 3 felony charges were dropped to ONE MISDEMEANOR. Instead of jail time and formal probation, Matt was able to get me 14 days of a work program, informal probation and 10 self-help meetings. I couldn’t have asked for anything better, considering the charges. My family and I were so relieved.

I have completed all the requirements of my probation and I plan on returning to Wallin & Klarich when the time comes to seek expungement. For legal counsel in Orange County, I wouldn’t recommend looking anywhere else.”


“Matt Wallin is an Exceptional attorney! I would highly recommend this firm. The service is like no other – from the timely and professional returned phone calls, their interest in your case, and strategic resolution. They take care of business and their customers! Thank YOU for bringing me peace during a difficult time! I wish you all the best!”


“Never experienced using a Law Firm before but sure glad we were introduced to Matt Wallin. He is absolutely an amazing attorney. He was eager to hear our story even when we didn’t think there was any hope Matt was able to shed light on the positivness with a negative situation. A average citizen doesn’t know the full extent of their rights and thanks to Matt on opening many doors for us. The process was smooth and he took care of everything with little to no involment from us. I was able to continue to live my normal life because of Matt. He created such a defence that I have never seen before. Obviously we came out winners at the end. I highly recommend you consult with Matt and his team before going anywhere else. You will not be disappointed. ”


“I can’t begin to tell you how much the offices of Wallin & Klarich has helped me. In 2012 I was falsely accused by my ex-wife for domestic violence in order to get an edge on our custody battle. After spending a boat load of money clearing my name in family court, I still had the burden of the arrest record still lingering in the CA criminal justice system. I work in an industry sensitive to this type of situation and I would certainly have a problem gaining employment in the future as a result. I was told that I could clear my name and remove my arrest record by petitioning the court. I was also told that it is no easy feat and that a very small percentage of petitions to remove arrest records are granted. ”
