What Sumner Law Group Llc does

Sumner Law Group, LLC is a privately held, boutique personal injury law firm headquartered at 7777 Bonhomme Avenue, Suite 2100, St. Louis, Missouri, with licensure extending into Illinois. The firm operates on a strictly contingency fee basis — clients pay no upfront attorney fees and the firm is compensated only on recovery — and is structured as a five-person team: four trial attorneys (Brent Sumner, Andrew Martin, John Greffet, K. Lindsay Rakers) and one paralegal (Marie Bacott).

The firm represents individuals and families in serious personal injury and wrongful death matters, with core practice areas spanning car accidents, tractor-trailer and commercial delivery vehicle litigation (including FedEx, Amazon, DHL, and USPS cases), motorcycle crashes, medical malpractice, premises liability and negligent security, daycare/institutional abuse, and wrongful death claims. The technical work product is built around traditional case functions — investigation, evidence preservation, electronic-log and driver-qualification record recovery, medical documentation, expert reconstruction, insurance negotiation, and trial advocacy — with no proprietary technology stack; the firm's public-facing digital infrastructure is limited to a marketing website, categorized blog, and video center. The trial-first orientation is central to positioning: the firm publicly advertises a willingness to take cases to verdict rather than settle early, supported by reported results including a $25 million negligent security verdict, a $14.2 million motorcycle verdict, and an $6 million 18-wheeler settlement.

Commercially, the firm runs a direct-to-client sales motion via 24/7 phone availability and website contact forms, with free case evaluations and no intermediaries. Distribution is augmented by an inbound referral channel from other law firms that route complex plaintiff work to Sumner, and by community-integration signals (board positions at Ladue Education Foundation and Cardinal Glennon Children's Hospital). The business model is single-revenue-stream: contingency fees from plaintiff representations, with no subscription, recurring, or alternative-fee products disclosed.
