KJC Law Firm

What KJC Law Firm does

KJC Law Firm LLC was a private personal injury and wrongful death litigation boutique founded in 2010 by Kathy Jo Cook in Boston, Massachusetts. The firm represented individuals and families in personal injury matters (car, truck, motorcycle, bicycle, construction, premises liability, product liability, medical malpractice, electrocution, explosions/fire, and aerotoxic syndrome cases), wrongful death claims, and labor/employment disputes including discrimination and unfair business practices. KJC positioned itself as a trial-ready plaintiff firm taking on corporations and insurance companies, marketing heavily on case outcomes including a $143M gas explosion verdict and multiple seven-figure settlements.

The firm's revenue model centered on contingency fee representation for personal injury matters, with free initial consultations as the primary client acquisition mechanism. Distribution relied on direct consumer engagement through the firm website, phone intake, an extensive legal education blog, video content, social media across five platforms, and attorney referrals. The firm was headquartered in Boston and served clients throughout Massachusetts with a team of 11-50 employees and over 125 years of combined litigation experience.

In September 2022, KJC Law Firm merged with Sheff Law Offices to form Sheff & Cook, with Kathy Jo Cook and Douglas K. Sheff as shared managing partners. The kjclawfirm.com domain now redirects to sheffandcook.com, and the firm no longer operates under the KJC Law Firm name. The merged entity continues the personal injury and wrongful death practice from Boston. No external funding, technology platform, or AI capabilities were disclosed at any point.

Broad incumbents

• Morgan & Morgan: Largest U.S. plaintiff-side personal injury firm with extensive TV/digital advertising and a contingency model; competes for the same Massachusetts consumer PI demand at much larger scale.
• Sokolove Law, LLC: National mass-tort and plaintiff-side PI firm with a Boston-area presence, using heavy marketing and referral networks; broader scale but overlapping client base in PI, nursing home neglect, and injury litigation.

Direct peers

• Lubin & Meyer PC: One of the largest plaintiff-side personal injury and medical malpractice firms in Boston/New England, with a comparable Massachusetts-only focus, contingency fee model, and trial-heavy approach against corporate defendants.
• Altman & Altman, LLP: Massachusetts personal injury and criminal defense firm with a broad PI practice (auto, premises, medical malpractice) and contingency fees, serving the same consumer client base in the Boston market.
• Breakstone, White & Gluck: Boston plaintiff-side personal injury firm with a similar contingency model, trial-ready reputation, and Massachusetts-only footprint; comparable in size and case mix to KJC.
• Law Offices of Jeffrey S. Glassman: Boston personal injury firm specializing in car accidents, slip-and-fall, and workers' compensation with a contingency fee model, targeting the same injured-individual segment in Massachusetts.
• Keches Law Group: Massachusetts-based plaintiff-side personal injury, workers' compensation, and medical malpractice firm with multiple offices and a contingency-fee model, directly competing for the same injured-individual client base.
• Sugarman & Sugarman, P.C. Boston plaintiff-side personal injury firm handling catastrophic injury, wrongful death, premises liability and product liability cases on contingency — overlapping core practice areas with KJC.
• Sheff & Cook (Sheff Law Offices): The merged successor entity to KJC Law Firm; a Boston plaintiff-side personal injury and wrongful death firm with shared management between Douglas K. Sheff and Kathy Jo Cook, making it the closest direct comparator for combined scale, practice mix, and Massachusetts market positioning.
