What Law Offices of John J. Sheehan does

The Law Offices of John J. Sheehan is a private Massachusetts personal injury and workers' compensation law firm founded in 1993 by Managing Attorney John J. Sheehan. Operating from offices in Wakefield (headquarters) and Boston, the firm represents injured workers, auto accident victims, construction accident victims, and other individuals across at least eight Massachusetts counties (Suffolk, Middlesex, Essex, Bristol, Barnstable, Norfolk, Plymouth, and Worcester). Core practice areas include auto accidents (car, pedestrian, bicycle, motorcycle, delivery, and rideshare), workers' compensation (claims, disputes, appeals, third-party claims, and lump-sum settlements), construction accidents (falls, electrical shock, trench collapses, equipment failures), workplace injuries (spinal cord, TBI, burns, amputation), slip and fall premises liability, and wrongful death.

The firm's business model is contingency-fee legal representation under a "No Fee Unless We Win" structure, with free initial consultations and no upfront client costs. Revenue derives from contingency percentages on settlements and verdicts; case results published on the firm's site range from $625,000 (pedestrian hit by car) to $1.5M (construction site steel I-beam accident). Service delivery combines in-office consultations at both locations, virtual consultations via Zoom/teleconference, and home/hospital visits for accessibility. The firm differentiates through full bilingual English/Spanish capability (including a Spanish-language website), 30+ years of litigation experience, BBB accreditation, 2026 Lawyers.com recognition, and an organic content strategy spanning YouTube testimonial videos, Facebook, X, and LinkedIn.

The team is intentionally lean: Managing Attorney John J. Sheehan, Office Manager/HR Generalist Santina Sheehan, and Senior Paralegal and Office Coordinator Mary Lopez, plus supporting legal professionals (1–10 employees total). There is no disclosed technology platform, proprietary AI tooling, app, API, or integrations; the firm is a traditional professional services practice. The firm is organized as Law Office of John J. Sheehan, LLC, a Massachusetts LLC, with no parent company, no institutional investment, no funding rounds, no subsidiaries, and no disclosed M&A activity.
