Fighting on Your Side
With offices in Wellesley and Worcester, Massachusetts, Sullivan & Sullivan LLP represents clients throughout New England and across the country in the most complex and high-stakes personal injury litigation.
Our practice is dedicated to those facing catastrophic injury or the wrongful death of a loved one — the cases where the stakes are highest and the need for skilled advocacy is greatest.
Over the past two decades, we have secured more than $400 million on behalf of clients and their families. Our attorneys bring both legal skill and personal dedication to every case, ensuring that clients receive not only strong advocacy but also the attentive service they need during challenging times.
Our experience spans cases involving construction negligence, major commercial vehicle accidents, and dangerous or defective products — including faulty roadside guardrails and unsafe power tools. Whether the harm is life-altering injury or tragic loss, we pursue every viable course of action to secure the resources families need for medical care, lost income, and long-term stability.

Generations of Representation
Sullivan & Sullivan LLP was founded in 1999 by three brothers — Richard, Mark, and Eugene Sullivan — continuing a legal legacy that began with their grandfather, Daniel J. Sullivan Sr., a 1918 graduate of Suffolk University Law School. All three grandsons followed in his footsteps at Suffolk, building a firm grounded in family values, integrity, and commitment to justice.
From its beginnings in Wellesley, Sullivan & Sullivan has grown into a 16-person firm recognized for its success in complex civil litigation, particularly in construction site accidents, product liability, and catastrophic injury representation. With offices in both Wellesley and Worcester, today the firm is led by Richard J. Sullivan, Founder and Managing Partner, and Mark D. Sullivan, Founder and Managing Partner. Richard’s wife, Tracie Sullivan, is the Office Manager, extending the family’s dedication to both the business and its people.
This family foundation has shaped Sullivan & Sullivan’s approach to practice: mentoring younger attorneys, fostering collaboration, and promoting balance between professional excellence and personal well-being. Over its 25-year history, the firm has earned a reputation for taking on cases that not only achieve life-changing results for clients but also drive meaningful industry reform.
Sullivan & Sullivan has played a key role in national table saw safety litigation since 2001, contributing to the development of improved guarding systems and potential new safety standards. Since 2016, the firm has been instrumental in exposing unsafe guardrail designs through product liability and qui tam actions, leading to enhanced roadway safety across Massachusetts and the country.
Today, the firm combines its deep trial experience with modern tools — including video depositions, animation, multimedia exhibits, and emerging AI technologies for document and medical record management. Sullivan & Sullivan also partners with consultants and focus groups to test case strategies and strengthen courtroom outcomes.
Beyond the courtroom, the firm remains deeply involved in community service. Richard J. Sullivan serves on the board of trustees at Dean College and supports ZUMIX, a youth music organization in East Boston, along with the Right Turn Foundation and Mildred's Dream Foundation. The firm also contributes to programs such as the Paul McLaughlin Boys Club and the Worcester Library Annual Fund, continuing its tradition of advocacy both inside and outside the legal arena.
