At JCO Law Firm, our Boston Criminal Attorneys fight harder than anyone else to make sure you get the best possible outcome. We help clients from all over Massachusetts during some of the most difficult times of their lives.

We know that when it comes to choosing a Boston Criminal Defense Attorney you have options – so why choose our firm? The reason is simple: We get you out of trouble fast, and we do so at an affordable price. At JCO Law Firm you get the representation you need at a price you can afford. Your Satisfaction is guaranteed.

We make three guarantees to each and every client we represent:

First, we guarantee that when you retain JCO Law Firm, our Boston Criminal Defense Attorneys will work with you to develop the best possible criminal defense available within your budget. 

Some clients want a criminal defense with all the extras – expert criminal defense witnesses, private investigators, laboratory analysis, and so on. We are happy to provide that for our clients. However, we also know that some clients just want the best defense they can get within their budget.  At JCO Law Firm, we custom tailor your defense to your budget. We even offer our clients free initial case evaluations and flexible payment plan options. When you do business with our firm the price we agree upon is the price you pay – no additional hidden fees – no tricks.

Second, we guarantee you the highest possible level of customer service. No unanswered phone calls. No wondering about the status of your case. 

Some law firms believe that clients should write a check and then leave the attorney alone to work his magic. At JCO Law Firm, our Boston Criminal Defense Attorneys know that we are here to serve you. We welcome your calls and are happy to provide detailed updates regularly on the progress of your case as well as answer any questions you may have along the way. We believe in a true partnership – one that values our clients.

Third, we guarantee you that we will fight harder on your behalf than anyone else. 

At JCO Law Firm, our Boston Criminal Defense Attorneys make it their mission to go above and beyond what other firms or attorneys will do. We stay up nights thinking about your case. That’s what makes our firm the best. We genuinely care about you and making sure you get out of trouble. Criminal Defense is what we do. In fact, it’s all we do.
