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. ...

Proceed with caution
At first, after reading the good reviews, I thought I made the right decision with choosing Mr. Duffy. Now, I’m wondering if they’re credible or even real. My experience with this law office wasn’t favorable to me or my case. I spent thousands of dollars on his representation and I am left wonderin...
We are sorry to hear that you are dissatisfied with our representation in your case. I am concerned that you would post an anonymous review without much detail regarding your specific dissatisfaction. I often find that unrealistic expectations play a role in those unhappy with their outcome. We strive to set realistic expectations for our clients and do not promote expectations that a case will be dismissed where it is not warranted. All of our reviews are true and accurate. We would encourage you to contact our office so we can address your specific concerns.

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 ...

One of the best decisions I made.
I thought it was going to be a fun night of celebrating the end of the semester, it turned out to be a nightmare. I made the not-so-smart decision to drive back home intoxicated and was caught. Getting arrested was terrifying. I had mixed emotions of fear, regret, guilt, and embarrassment. I ca...
"I highly endorse Bill Duffy. In my 30 years as an attorney, I have not met an attorney with a higher degree of character and integrity than Bill. He deeply cares about his clients and puts his clients' concerns and welfare first. He is a strong advocate and works very hard to achieve the best result for his clients, yet he is very practical and pragmatic in his approach."
"Fantastic attorney. I have seen him fight hard for his clients. I absolutely endorse this attorney"
"Bill is a wonderful attorney. I have worked with Bill and seen first hand how he fights for his clients and how experienced and talented he is in a courtroom. I endorse this lawyer."
"William is an exceptional attorney. He knows the law, the judges, and the DA’s. You can’t ask for better representation on a DUI."
"I endorse this lawyer. Mr. Duffy is a talented, experienced, and skillful DUI defense attorney. He has a solid reputation for analyzing every piece of evidence and employing the best possible strategies to exploit the specific weaknesses in his client's DUI cases."
"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."
"Mr. Duffy is an excellent criminal defense attorney that is specialized in DUI defense. He is extremely professional and treats his clients as if they were family. As a colleague he is extremely helpful and has given me excellent advice on my DUI cases over the years. I highly recommend Mr. Duffy for any criminal case you may have."
