Founder and Attorney, Duffy Defense, PLLC


Attorney Alec Duffy was raised in a small town in northern Wisconsin, the third in a line of lawyers in his family. He grew up learning to hunt, tend to cattle, and navigate the ins and outs of the legal system, thanks to his grandfather, a long-time attorney. 

Mr. Duffy is fascinated by all areas of law, but he chose to pursue a career in criminal defense because he’s passionate about helping others get their lives back on track. 

He’s seen firsthand how jail sentences and criminal records can derail a person’s future, and he puts his education and background to work fighting to help his clients secure a second chance. He firmly holds to the belief that everyone makes mistakes and one bad decision shouldn’t define a person’s future.

Mr. Duffy takes a multi-directional approach to securing successful court outcomes. He accepts a variety of criminal defense cases and has achieved successful dismissals in a number of high-profile cases involving felony assault. 

He has attended a number of seminars exploring the science and law behind DWI investigations. His work in these areas has helped him achieve impressive wins in the field of DWI cases, particularly in DWI cases involving marijuana impairment. 

Due to Mr. Duffy’s work highlighting issues with Minnesota’s marijuana investigation protocol, one of his client’s criminal DWI citation in a recent case was dropped, and his client was able to plead to a non-criminal citation. 

In light of Minnesota’s recent legalization of marijuana, this was a huge win that Mr. Duffy believes has changed prosecutorial charging decisions moving forward. 

Alec Duffy views his role as a criminal defense attorney as that of a legal life coach. He understands that facing criminal charges can be a tense and stressful affair. He strives to bring compassion, dedication, and a sense of humor to each case, helping his clients feel hope for the future and the outcome of their criminal cases. 

If you’re looking for a criminal defense lawyer who fights passionately for his clients, has achieved groundbreaking success in the area of DWI prosecution, and believes passionately that every person deserves a second chance, look no further than Duffy Defense’s founding attorney, Alec Duffy.
