Our Commitment Is More Than Legal – It’s Personal

Karen and Leslie have been working as a successful team together for two decades representing individuals and their families in personal injury cases. They have over 25 years of experience each working in big law firms in Boston and Cambridge. They exclusively represent those injured in accidents in Massachusetts. They are long time Massachusetts residents. Before establishing Nadeau Harkavy LLC, Karen and Leslie worked as a team for 15 years at a Cambridge and Boston law firm where they managed and developed the personal injury department. During this time together, they created systems and guidelines for handling personal injury cases at the firm and supervised other attorneys, paralegals, legal assistants, law clerks and receptionists from how to answer the phone when a client called to the best trial strategy for a case. These experiences were invaluable for their own firm, and they developed close relationships in the personal injury field both professionally and personally.

Karen and Leslie realized early on that they were a great fit and had something special that could not be duplicated. Their philosophies on how to handle personal injury cases, how to treat clients and their incredible work ethic aligned. They obtained excellent results on cases and had many happy clients with whom they developed relationships and friendships over the years. Their firm was founded on the philosophy that they would use their more than 60 years combined experience representing victims to provide their clients with the best possible legal advice, individualized attention, and prompt communication with an ongoing commitment to the highest standard of excellence in a boutique setting.

Nadeau Harkavy LLC’s focus is to place the client at ease from the very first phone call during one of the most difficult times in their lives. Through experience gained after years of personally handling thousands of injury cases, Karen and Leslie can easily help clients understand the law that impacts their case to make the best decisions and navigate their clients’ cases through a complex system of laws and procedures that often feels very stressful and insurmountable. Karen and Leslie work tirelessly to obtain the most successful outcome for their clients.
