Colleen C. Cook


Colleen is a seasoned litigator and experienced trial counsel, focusing her practice on complex business litigation, employment, commercial real estate, contract, regulatory, and tort matters. Colleen has spent the last twenty years representing private and public clients at every level of state and federal courts in Massachusetts and has been admitted in many jurisdictions across the country pro hac vice. Above all, Colleen is a trusted advisor to her clients with a no-nonsense approach who aims for the most practical way to resolve a conflict and reach her client’s goals with maximum efficiency.

Colleen’s philosophy: she blends diplomacy with her competitive spirit which makes her perfectly poised to tackle any litigation matter— routine or cutting-edge.

She has tried a number of cases successfully for her clients and navigated complex business entanglements. Some of her victories include representing a distributor in a two-week jury trial resulting in a $6.4 million verdict for breach of distribution agreement and fraud by the manufacturer which included an award of punitive damages and attorneys’ fees, and a multi-phased trial lasting two months stemming from conversion of escrow funds and recovery of over $20 million to her clients. In addition, Colleen has prevailed in arbitrations, including a matter in New York in which she obtained a $12.9 million award.

Colleen regularly advises her employment clients regarding disciplinary action and termination, discrimination matters, personnel issues, statutory compliance, executive compensation, restrictive covenants (including non-competition, non-solicitation, and non-disclosure), trade secrets, and severance agreements. In two of her current employment litigation cases, Colleen is defending a Fortune 500 company involving denial of life insurance benefits and claims under ERISA.

She was appointed as Special Assistant Attorney General to defend the Governor of the Commonwealth of Massachusetts, Secretary of Health and Human Services, and Department of Public Health in cases filed concerning registration of dispensaries under the Medical Marijuana law where she successfully defeated several preliminary injunction motions.

Colleen is a Board member of the Massachusetts Defense Lawyers Association and a past Board member of the Massachusetts Children’s Trust. Colleen served on the Conservation Commission for her city for several years and has judged Yale's national moot court competition. She also was honored by Women’s Business Boston Journal as one of the top 10 lawyers in Massachusetts, New Hampshire and Rhode Island for her "top notch legal services and advice."

Colleen kicked off her legal career with a clerkship for the Massachusetts Superior Court. Colleen is a 1992 graduate of the University of Vermont and graduated from Northeastern University School of Law in 1997. She also attended the Program for Women in Politics and Government at the University of Massachusetts after college.
