The Michael J. Brennan Injury and Accident Lawyer offices have been established on the belief that every person has the right to the highest level of legal advice and service. We follow this premise in each and every one of our interactions with our valued clients. We, therefore, return phone calls within 24 hours, follow up on e-mails immediately, and make sure that clients are frequently updated about the progress of their case.

We will work to help you recover the compensation that you are eligible for by using negotiation strategies and get the best possible outcome for you. However, if the best possible outcome is not possible through negotiations alone, Michael will not hesitate to take your case to court.

We pride ourselves on offering our clients a high level of service and dedication. At our firm, your case is not just handed over to an associate lawyer. Instead, Michael will take a personal interest in your case, and will resolve your concerns.
