Highly recommend!

“I had an excellent experience working with Maas and Russo. From the very beginning, they were professional, responsive, and communicative. They always took the time to explain the process clearly and made sure I understood all of my options. What impressed me most was how dedicated they were — they ...worked tirelessly to achieve the best possible outcome for my situation. I truly felt supported every step of the way. I am very grateful for their hard work and expertise, and I would highly recommend Maas and Russo to anyone in need of knowledgeable and reliable representation.”

I highly recommend Mr, Maas

Mr. Maas is the best defense attorney in Solano County, He is fair, compassionate, and very smart. I was facing some serious time on some false accusations, I could possibly had spent the rest of my life behind bars but thankfully I hired Mr. Maas and because of his outstanding job I am freed today.

DUI Charges

I hired "Maas Law Offices" to handle my DUI case. Mr. Maas reviewed all reports issued by the police. With his advanced knowledge and understanding of the Calif. Vehicle Code, he requested a DMV hearing. At DMV hearing he proved to them that, my stop and detention were outside the legal parameter s...et forth in the Calif. Vehicle code, which they agreed with. I retained my driving privileges. The court is a totally separate issue and charges, from the DMV hearing. Once again Mr. Maas's expertise and In-depth understanding of the law and legal procedures, piloted me through to a dismissal of all charges. My family is so very grateful for his understanding, compassion and quality of professionalism. The cost of Mr. Maas's legal services was minimal to the cost I was facing with the conviction. I was not burdened by additional cost at any point. The "Maas law Offices" provide very Quality Legal Services for a family of modest financial means, and with "sincere" compassion as well. Tom saved me from deep depression and for that I am forever GRATEFUL to he and his staff! I feel you can spend more, but you absolutely WILL NOT GET MORE! Sincerely, Deryl D (last name withheld for privacy)

Dedicated, Expert, Compassionate Counsel

I recently hired Thomas Maas to handle a challenging situation that involved two DUIs and a felony child abuse charge. He consistently provided knowledgeable, expert counsel, and was supportive without being unrealistic about the options. Sitting in the courtroom, listening to the attorneys for other... clients, I was repeatedly reminded of how much better Mr. Maas was. I will recommend him and his expert services to anyone needing high-quality criminal defense.

thankfully free

I retrained Mr. Maas for a felony charge that was a difficult case to defend. Mr. Maas represented me in a professional intelligent manner that afforded me to plead no contest. He managed to negotiate a deal that allowed me probation and no jail time. I found Mr. Maas & his associates to be extremel...y helpful and would refer him to anyone who needs a full service defense attorney.
