What Sigman, Janssen, Stack, et al does
Sigman Janssen Injury & Disability Lawyers is a Wisconsin-based personal injury and disability law firm founded in October 1925 by Abraham and Samuel Sigman. Operating as a privately-held partnership from its Appleton headquarters at 303 S Memorial Dr, the firm serves individuals and families across Northeast Wisconsin — including Appleton, Green Bay, Oshkosh, and surrounding communities — through nine practice areas: personal injury, car accident, motorcycle accident, truck accident, dog bite, slip and fall, Social Security Disability, workers' compensation, and wrongful death. The firm operates exclusively on a contingency fee basis, meaning clients pay no upfront fees or costs and the firm is compensated only if it obtains a settlement or court award.
The firm is staffed by four active attorneys — James P. Pitz, Anastasia Burkham, and Wesley Groot — plus a retired attorney (Mark V. Sewall), supported by a team of twelve paralegals, legal assistants, legal writers, and administrative staff. The firm's go-to-market is direct-to-consumer: prospective clients reach the firm through organic search on location-specific pages, the website's free case evaluation form, a toll-free phone line (877-888-5201), or in-person consultations at the Appleton office. Distribution is marketing-light with no intermediaries, referral networks, or third-party lead generation partners.
The firm's revenue model is outcome-based contingency fees aligned to client recovery. Attorney James Pitz has personally represented more than 1,500 clients and is credited with more than $100 million in combined client recoveries across the firm's practice areas. The firm preserves no proprietary technology platform and emphasizes its nearly 100-year brand history, multi-attorney expertise, and proximity to the Outagamie County Courthouse as its primary competitive differentiators. The firm is independently owned by its attorney partners with no external institutional investors or parent company.
