Petersen & Petersen Inc.

What Petersen & Petersen Inc. does

Petersen & Petersen is a plaintiff-side trial law firm headquartered in Chardon, Ohio (Geauga County), founded in 1997 by partners Todd and Susan Petersen. The firm represents injured individuals — never insurance companies, hospitals, or large corporations — across personal injury, medical malpractice, wrongful death, nursing home negligence, auto and trucking accidents, product liability, premises liability, gas explosion, employment discrimination, criminal defense, business disputes, and DUI/OVI matters. Operations are run by three named attorneys (Susan Petersen, Todd Petersen, and Colleen Del Balso) supported by what the firm describes as "nine on the books" staff, with combined 80 years of trial experience cited across the team.

The firm's technical edge centers on a proprietary Electronic Health Record (EHR) inspection methodology, through which it obtains court-ordered inspections of live EHR systems to surface audit trails, metadata, revision histories, and hidden data not produced in standard discovery. This capability has been used to uncover falsified nursing home records and backdated documents, yielding concrete outcomes such as 845 pages of medical records uncovered in a single matter and over $221,000 in discovery sanctions. Service delivery is direct-to-client, supported by free initial consultations and a contingency fee structure for personal injury matters, with case acquisition driven by reputation, attorney referrals, community involvement, and professional recognition rather than paid marketing channels.

The business is privately held by the founding partners with no external investors or funding. Reported case outcomes include over $65 million in cumulative client recoveries since 2010, a $17 million natural gas explosion settlement obtained on day 5 of trial, a $3.25 million medical malpractice settlement for loss of limb, and a $1.4875 million medical malpractice jury verdict in Cuyahoga County. The firm is currently litigating Paganini v. Cataract Eye Center before the Ohio Supreme Court, challenging Ohio's medical malpractice damages cap on as-applied constitutional grounds — a precedent-setting posture with material implications for the firm's future case economics.
