Attorney Michael DelSignore is a Massachusetts OUI Lawyer who has spent more than 20 years making sure his clients never have to wonder if they made the right call.
For anyone reading this, the situation is likely an urgent one. Either you or someone you care about is facing an OUI charge or a serious criminal accusation in Massachusetts. The phone is full of law firm names. The inbox may already be flooded with generic advertisements. Every attorney seems to promise the same outcome.
Here is the truth: not all criminal defense lawyers are the same. When a license, a career, a clean record, and personal freedom are on the line, that difference matters more than almost anything else in the world right now.
“Attorney DelSignore did not become a defense lawyer to process cases. He became one to fight them — and to make sure every single client feels that passion from the first phone call to the final outcome.”
A career built around a single mission
Unlike law firms that handle a broad range of practice areas, Attorney DelSignore has spent over two decades building one of the most recognized OUI and criminal defense practices in Massachusetts. This is not a side practice or a volume operation. He knows Massachusetts OUI law with a depth that comes only from years of singular focus — the science behind breathalyzers, the vulnerabilities in field sobriety testing protocols, and the procedural arguments that can change the outcome of a case before it ever reaches trial.
That level of focus is not accidental. It is the product of a deliberate commitment to his clients, repeated case after case, year after year.
Experience that shows up in the courtroom
Attorney DelSignore has been recognized by Super Lawyers, named among the top criminal defense attorneys in Massachusetts, and selected for inclusion in the National Trial Lawyers Top 100. These are not self-awarded distinctions — they reflect a track record that independent organizations and fellow legal professionals have validated over many years.
More important than any award, however, is the record built inside Massachusetts courtrooms at every level. Attorney DelSignore knows the prosecutors. He understands the judges. He has cross-examined breath test operators, challenged the science behind field sobriety testing, and argued suppression motions that have transformed outcomes in cases other attorneys would have resolved with a quick plea. That courtroom experience is irreplaceable — and it belongs to every client he represents.
“Recognition from the legal community is meaningful. But what truly drives Attorney DelSignore is the call from a client saying their case was dismissed — and their life is back on track.”
Clients work directly with Attorney DelSignore
One of the most common frustrations people experience after retaining legal counsel is this: they hired the senior attorney they met during the consultation, only to find themselves working with a junior associate they had never spoken to. When a client retains Attorney DelSignore, they get Attorney DelSignore — not a paralegal, not a junior attorney. Attorney DelSignore will do all the major work on the case. You will speak to him directly about your case and throughout the process.
The Massachusetts OUI system is not designed in the defendant’s favor — but Attorney DelSignore knows how to navigate it
Most people arrested for OUI in Massachusetts believe the evidence against them is airtight. The breathalyzer produced a number. The officer wrote a report. But the reality is far more complex. Massachusetts law imposes specific requirements governing how breath tests must be administered and maintained, what an officer must observe before conducting field sobriety tests, and how a traffic stop must be legally justified. When those protocols are not followed with precision — and they frequently are not — a real opportunity exists to fight the charge.
Attorney DelSignore has built his reputation on identifying those opportunities and pursuing them aggressively. He does not approach a case searching for a plea. He approaches every case searching for a win.
Attorney DelSignore has written the book — literally
Attorney DelSignore is the author of one of the most widely read OUI defense legal blogs in Massachusetts. He has published extensively on changes in OUI law, breathalyzer admissibility rulings, and evolving defense strategy. That ongoing commitment to legal education means his clients benefit from the most current knowledge available in this area of law — not strategies that produced results a decade ago.
What every client deserves
You deserve someone who you can trust their judgment and rely on their advice. Attorney DelSignore will explain the good and bad about your case why you may be found guilty and why he thinks the case could also result in a not guilty verdict. Attorney DelSignore will try to give you all the information for you to make a great decision for youself.
An OUI conviction in Massachusetts can cost a person their license, their employment, thousands of dollars in fines and insurance increases, and follow them throughout the remainder of their professional life. The decision made about legal representation in the next few days may be the most consequential one of the year.
Attorney DelSignore has dedicated his career to ensuring that when clients choose him, they never have cause to doubt that decision.
