“You want to read this!”

My daughter was arrested for a DUI and failed the breathalyzer. Friends said no attorney could get her off this. Well, they never met Michael- he was brilliant, no other word to describe it. Even the courthouse clerk told my daughter she had a good attorney and that he’s a nice guy. Michael - I thank you from the bottom of my heart for giving my daughter another chance with no criminal record.

Client Reviews
Michael was very professional and explained the process clearly and told us to be patient. After one year the charges got dismissed in the trial. Excellent knowledge of the court systems in the area of Boston. Would highly recommend him Ashwani
A careless decision on my part left me facing charges which would have severely hampered my ability to stay employed and support myself. But attorney DelSignore's skillful analysis and challenging of the evidence against me resulted in a conviction on a lesser charge. Now I'll be able to go on with my life, having learned a lesson I'll never forget. Thank you, Michael. Scott
Mike stuck with my case for 3.5 years and always kept me informed regarding the status. Ultimately, because of his due diligence, we ended up with an OUI not guilty verdict. This case could have gone many ways but his thorough review of the case and exceptional preparedness for trial ultimately drove a positive outcome. Thank you Mike! David
Michael DelSignore did an amazing job with my case! Either him or his partner Julie was always available to answer any questions I had and helped walked me through the entire process. I could not have done it without them! I highly recommend choosing this law firm to deal with your legal needs, you will not be dissatisfied. Ashley
I cannot express the gratitude towards both Michael and Julie for their amazing work and help. It was a very stressful event and they certainly put me at as much ease as possible. From start to finish it took 14 months and all the way through they were both very engaged with me. Today was worth the wait, Michael was great in court and I was rightfully found not guilty. I would recommend Michael and Julie over and over again. Claire
