⭐️⭐️⭐️ I can’t thank Michael Berezin enough for what he did for me. My child’s mom made false allegations and even injured herself to get me arrested. I was already on probation from another false case two years ago that I had pled no contest to just to get out of jail, so things were looking really bad. When I first spoke with Michael, he spent almost an hour on the phone with me, listened to everything, and didn’t charge me a dime. He told me he’d try to get the DA not to file, and that’s exactly what happened. Once he saw the proof I had — videos and recordings showing how abusive my ex really was — he knew I was telling the truth. Michael spoke to the DA, and they decided not to file the case in Placer County. I was honestly shocked and so relieved. Now I can focus on family court and getting my daughter back. I’m so grateful for Michael — he truly saved my future. This is a real story, no joke. Thank you so much !!!!!!

I can’t thank the Tiemenn Lawfirm, in particular Michael, enough for the amount of time and effort they/he put into my case. You can tell this is a Lawfirm that actually cares about each client and this isn’t just a business to them. Without Michael, my life would look drastically different than what it does today. He was honest, upfront, went above and beyond what was asked of him, and to top it off, extremely fair on cost . This is a Lawfirm that definitely operates on an integrity first basis. 100/100 stars for them! Can’t thank you guys enough!

Attorney Aaron Cadiz represented me in traffic court after I received two speeding tickets in Tulare County. He handled everything with professionalism and care, clearly explaining each step of the process. Thanks to his help, one of my cases was completely dismissed through the Start Smart Program, and the other was reduced to traffic school meaning no points on my license and no increase to my insurance premiums. I’m really grateful for his diligence, guidance, and genuine effort to help me through a stressful situation. Highly recommend Aaron to anyone who needs an attorney who actually looks out for their clients.

Review for Tiemann Defense Services Tiemann Defense Services represented me during a very challenging legal situation, and I couldn’t be more grateful for their support. From the very beginning, they made the entire process feel seamless and less overwhelming. Their team worked diligently to have my charges reduced, and they went above and beyond in investigating every detail of my case. They uncovered crucial evidence that ultimately worked in my favor—something I don’t believe many other firms would have taken the time to find. I especially want to recognize Attorney Michele Berzen. His professionalism in the courtroom and his strong investigative skills were nothing short of exceptional. He truly fought for the best possible outcome for me. Thanks to Tiemann Defense, I was placed in the right program—one that led to the most positive outcome for my case. Their dedication and expertise made what seemed impossible, possible. If you’re looking for a defense law firm in the Greater Sacramento area or Placer County, I wholeheartedly recommend Tiemann Defense Services. They didn’t just represent me—they gave me a second chance, and for that, I’m truly thankful
