Professional Profile:
Hello. Thanks for visiting!

My name is John C. Olivieri, Esq. I am a Massachusetts Criminal Defense Attorney, and the Founder and President of JCO Law Firm, PC. When I moved to Massachusetts from Washington DC, I had one goal in mind: Create the best Criminal Defense Firm in the Greater Boston area.

Every day, I work hard to make sure that’s exactly what JCO Law Firm is – the best! So, as I said, I am a Criminal Defense lawyer, and the founder and President of JCO Law Firm – but that’s not all I am: I am native New Yorker, a small business owner, a son, a brother and a dog owner. I am a political activist, a traveler and a huge sports fan, too!

I began my legal career in Criminal Defense. Early on, I interned at the District Attorney’s Office in Westchester County New York, and at the District Attorney’s Office in Silver Spring, Maryland. I have worked for the prosecution. I know how they think, and I know how to beat them.

After receiving my Law degree, I went to work in London, at the prestigious Law offices of Wilmer Hale Cutler Pickering and Dole, LLP. But I was dissatisfied working at Wilmer Hale.
I wanted to open my own shop. I wanted to get back to Criminal Defense. I wanted to fight for those who couldn’t fight for themselves.

I decided to leave big law life and big law paychecks, and came to Boston to open my own Criminal Defense Firm – and I did, JCO Law Firm, and we have been going strong since. Fighting prosecutors, negotiating plea bargains, representing our clients at trial and guiding them through the complex Massachusetts criminal justice system.

So what makes JCO Law Firm different than all the other Criminal Defense firms? Three things: First, no tricks, no hidden fees – we tell you what our prices are right up front. Second, we provide the highest level of customer service so when you are with us, you’ll feel like you’re our only client. Third, we fight harder than anybody on your behalf, and prosecutors know that. If you need help, call us today at 617.475.0581, and a receptionist will schedule your free case evaluation!
