Thanks Duffy
Left message for Duffy that boyfriend was bailing out of jail and needed a lawyer asap. He called me back right away and represented my boyfriend on a very complicated case. Duffy is a very professional and knowledgeable criminal defense lawyer. He was able to get my boyfriend a very fair deal for the felonies he was convicted of. Thank you Duffy. Girlfriend of Mr S. Lewis

Mr. Duffy is great!
I have worked with William Duffy on two related occurrences: initial handling of a DUI and a recently the expungement of that same DUI. Duffy and team were very clear with what where I stood, timelines, and expected outcomes. He was able to get an incredible outcome for me in the initial case and a quick turnaround for the expungement.

Amazing lawyer
Mr. Duffy has been an amazing lawyer. He took the time out to make sure I completely understood my situation and what we could do to get the best result. Also took the time to speak with my family and kept them up-to-date with the whole situation . He worked very hard on my case and got me a deal that was unheard of by many. I'm very grateful for what he has done and the man sincerely cares. Another great aspect was that he was very easy to get in contact with and the staff was amazing also. I highly recommend him to anyone that needs a great lawyer.

Excellent legal experience
I was on a student visa in the U.S and made the biggest mistake in my life followed by telling police what I did not mean, terrible mistake. Although I don't know how my life would be since that point, Mr.Duffy helped me get my case dismissed, which I cannot thank him enough for. He helped me greatly by making almost the best outcome(which is pure luck that the legal system lost my file) possible. My experience working with his team, including Mindy and Mark was excellent too, very professional and kind. Thank you for all the hard work! I appreciate it very much!

DUI & Expungement
The lawyers at C.A.R. Law, the Law Offices of Todd Landgren were very professional and helpful. They took care of my case and helped me navigate the process. I was so pleased with the service received that I've used them for the expungement as well. I would recommend their services to anyone in need.

Used for dui case and expungement
I used this law firm to handle my dui case three years ago and my expungement following three years of probation. The dui case was handled professionally will everything being clearly explained. Following three years of successful probation, I qualified for expungement. The process was very straight forward.

Fought for the best deal
Mr. Duffy exceeded my expectations when it came to handling my first offense DUI. Not only did he make sure my case was negotiated for the best outcome on my behalf, he also listened compassionately as he took the details of my life circumstance to get a better picture of who I was as an individual. His team has a lot of heart as well.

Excellent!
My husband and I were in need of an attorney, after researching several law offices we contacted Attorney, William Duffy and had a phone consultation with him. We immediately got a sense of relief talking to him about our cases. We could tell how knowledgeable he was and he was able to answer all our questions. We felt confident that he would be able to help us. Every time I emailed him he responded promptly on the same day. Once our court date came up he reminded us that he would be appearing on our behalf. He was able to get our cases dismissed and we are so grateful to have found Attorney William Duffy and his team. Thank you!

The best. Straightforward, respectful, professional.
Just when you think your situation is complicated, Mr. Duffy makes everything simple and clear. Really tough to find a great lawyer with integrity and loyality in California these days, and he is it. He takes care of business quickly and accurately, and is very fair in his fees. Thanks again for the great work you did for me.

Great Lawyer
I had the pleasure of working with Mindy Lemmings and Attorney William Duffy on my early termination of probation and expungement which was a positive outcome on my case. Mindy has been very prompt to respond to my questions throughout the case and she is very pleasant to to work with. Both Mindy and Attorney William Duffy are professionals, I would recommend them both.

When in doubt...hire Duffy
Very grateful for the services of Mr. Duffy and his assistant, Mindy. Both so kind and helpful. My court date was changed several times so I was grateful to have Mr. Duffy show up as I could not take that much time off work. He even helped me with some other forms on the side that needed to be filled out aside from my DUI court documents. Very thorough, and straight to the point. I was not misled in anyway. He even somehow reduced my DUI 6-month program to a 3-month one. Highly recommended if you find yourself in a similar situation.

This team helped me attain the best possible outcome
Mr. Duffy and Mindy made this process as easy as it possibly could be. Mindy probably spent more time comforting me than she had time for. I will always appreciate how kind and gracious this office was to me. I was told right away what to expect and they took their time explaining everything to me in a clear and concise way. This wasn't a fun journey but they were patient with me and provided any information that I needed. I feel like things could have been far worse if I had not hired them to represent me. I would definitely recommend this office. I felt in safe hands and I truly felt I didn't need to worry as much as I did. I am very grateful and thankful for their guidance and represtation.

Professional, personable and straight to the point
Mr. Duffy attended to our complicated case with ease and confidence. We were very anxious about things and Mr. Duffy took the reigns and he worked very hard to attain the best results possible, given our circumstances. He had excellent rapport with the judge and was able to help us get a much more positive outcome than expected. He returns phone calls and emails diligently, and sincerely wants to facilitate the best outcome for his clients. Highly recommended.

Best DUI Attorney
These guys are the best. Initially I contacted 4 different attorneys and 2 would not give me the time of day due to being overworked. I received Todd's information through a family friend that had similar issues whereby they received excellent results from their case. The team was able to walk me through alot of the process at the very beginning. Every team member, including Katherine was knowledgeable and lowered my stress levels considerably. After meeting with Michael in person he explained the likelihood of outcomes given the situation and made me feel very comfortable about how he was going to attack the problem. We had some issues with the police department not providing the requested video surveillance until the day before the case. We were able to push out the date until we could have time to review. The team walked me through the public hearing and the DMV hearing which I wasn't aware they were separate to begin with. In total I believe we received closure on the matter within a few months and I was on track to get my license back. These guys are great and I am glad I hired them because given my record this would have been a lot worse.

"I've known Mr. Duffy since law school, when we studied together regularly. His commitment has inspired me ever since. I have had the opportunity to review some client matters for a second opinion after the client worked with Mr. Duffy. In each of those matters, Mr. Duffy obtained the absolute best result possible under the circumstances. In one case, his efforts spared the client from 22 years in state prison after a string of armed robberies. Based on the top-quality work I've seen in his cases, I heartily recommend him."
