KJC Law Firm, LLC
10 Tremont St 5th Floor
Boston, Massachusetts 02108

American Board of Trial AdvocatesKathy Jo Cook is the managing member of KJC Law Firm. She represents people who have been injured and people and businesses that have suffered an economic loss. This includes individuals who have been injured in a car crash, on a construction site, or by a doctor, nurse or lawyer. This also includes individuals and businesses which have been harmed by another as a result of unfair business practices or discrimination in employment.

Kathy Jo began her legal career at Lubin & Meyer, P.C. during law school. She joined Keches & Mallen, P.C. thereafter, where she handled complex claims on behalf of injured plaintiffs for 13 years. Kathy Jo litigated the first successful claim in Massachusetts to hold that an insurance company’s meritless appeal of an injured worker’s verdict was a bad faith insurance practice and violated the Consumer Protection Statute, securing the original judgment of more than 3 million dollars and an additional 4.2 million dollar punitive judgment against the insurance company for that practice. In 2010, she prevailed in Law v. Griffith, 457 Mass. 349 (2010),a case which was deemed to be one of the most important decisions of the year and one which continues to aid plaintiffs seeking damages at trial for medical expenses. Kathy Jo was on the Steering Committee in the Columbia Gas cases, which obtained a settlement of $143 million for residents of the Merrimack Valley who suffered losses as a result of the explosions in 2018. More recently, she and her firm are fighting for the rights of business owners who have suffered significant losses as a result of the COVID-19 pandemic and whose insurance carriers refuse to pay their claims.

Kathy Jo’s outstanding abilities have been recognized by her peers and legal observers. In 1999, she was named by Massachusetts Lawyers Weekly as one of the top five "up and coming" attorneys in Massachusetts, and in 2007, she became the third lawyer ever to be inducted into the Lawyers Weekly "Hall of Fame." In 2008, Kathy Jo was named as one of the Top 50 Women Lawyers in Massachusetts by Law & Politics Magazine (Best of Boston), and she has been named as a Super Lawyer by that same publication every year since. In 2010, Kathy Jo was admitted to the American Board of Trial Advocates, a distinguished organization which is open by application only to those with significant trial experience, and in 2016, she was recognized by Lawyers Weekly as one of the Top Women of the Law.

Kathy Jo has been rated as “AV Preeminent” by Martindale-Hubbell Law since 2006. This is the highest rating possible and is given only to lawyers who have very high to preeminent legal ability and who embrace very high professional standards. She has also been rated by Avvo as “Superb.”

Kathy Jo has also been active in bar association work and other efforts to promote fairness, justice and equality in the trial bar as well as society at large. She serves as the Massachusetts Chair of the Business Interruption Litigation Committee of the American Association for Justice. She is a former President of the Massachusetts Academy of Trial Attorneys and the Women’s Bar Association of Massachusetts, where she continues to serve in leadership. She is a member of the Civility & Professionalism Committee of the Massachusetts Bar Association, where she has also served as Chair of the Judicial Administration Section Council, Co-Chair of the Plain English Jury Instruction Project, and as a member of the Standing Court Management Advisory Committee and the Strategic Planning Committee. She has served as Co-Chair of the Legislative Policy Committee and the Executive Management Board of the Massachusetts Employment Lawyers Association. Kathy Jo has also served on the Civil Right to Counsel Task Force, the Civil Rights and Civil Liberties Section Council and the Diversity and Inclusion Section Council of the Boston Bar Association.

Kathy Jo frequently lectures on substantive legal issues, litigation techniques and gender equality at area law schools, professional conferences, and Massachusetts Continuing Legal Education. She has been featured in a number of publications, including the National Law Journal and Massachusetts Lawyers Weekly. She has received numerous first place awards in national writing and trial competitions, including the Association of Trial Lawyers of America National Trial Competition. Her writings have appeared in numerous publications, including the American Judges Association Journal and the Cleveland State Law Review.

About her work Kathy Jo says, "My focus has always been on justice. To me justice means working to promote equality, to protect important civil rights, and to help individual people, workers and consumers when they are injured.”

Kathy Jo is an honors graduate of Suffolk University Law School and the University of Houston. She is licensed to practice before all state and federal courts in Massachusetts.
