How GLP Personal Injury Attorneys Levels the Playing Field with Supio

GLP Personal Injury Attorneys has spent more than 40 years building the largest plaintiffs' personal injury practice in the Pacific Northwest: roughly 45 attorneys and 160+ employees across ten Washington offices, from Seattle to Spokane. The firm's identity was set early. Cydney Campbell Webster joined as a legal intern in 1992, when GLP Attorneys was three attorneys; she became the first shareholder after the founders and the firm's first woman shareholder. Her philosophy became the firm's: take the difficult cases other firms pass on and work them all the way through litigation.

That choice has a cost, and it is measured in paper. The firm ran on medical records in blue three-ring binders until COVID forced digitization. Going paperless solved storage, but it didn't solve scale—because as GLP Attorneys went digital, so did every defendant. "Large firms, large construction companies, large public entities have the ability to give us literally thousands of pages digitally," says Curtis Williams, GLP Attorneys' senior litigation paralegal of 18 years. "We refer to it as a document dump. The intention is: well, here you go, have fun looking through it."

On GLP Attorneys' biggest cases, a dump like that used to consume two or three paralegals doing nothing but document review, while opposing counsel counted on the delay. "We're working against larger law firms. They might have more staff than we do, and they have all the information," Campbell Webster says. "We have to get through it all."

GLP Attorneys didn't stumble into AI; it watched the category for four years before buying. Campbell Webster chairs the firm's AI committee, formed when the shareholders began asking what autonomous vehicles and machine learning would mean for a personal injury practice. When AI tools for PI firms matured in 2025, the committee's first filter wasn't features. It was security. "GLP Attorneys did not want to be the test case for violating somebody's HIPAA by putting medical records in an open-source system," Campbell Webster says. "We knew right away we needed to give our staff access to something secure. That was my first selling point to the rest of the shareholders."

A meeting with one of Supio's founders and a demo showing case economics and record analysis the firm had been doing by hand, closed the decision. GLP Attorneys now runs its case files through Supio, and adoption has spread from early champions to the firm's most committed skeptics. Senior Case Manager Amy Jo Pearson, a 30-year industry veteran, started out fact-checking every answer Supio gave her.

"Supio has proven time and time again—every time I fact-check it, it's pulling right from the medical records, and it points to the records so you can verify with your own eyes. That's where my trust is now."

Today the whole case lifecycle runs through it. Paralegals generate medical chronologies and demand drafts that used to take one to two days in about an hour. Attorneys query depositions and discovery directly instead of emailing a paralegal and waiting hours for a single MRI report. Partner Mel Westberg uploaded her own medical summary format so Supio now produces summaries the way she writes them. And Williams has built his own arsenal—contradiction prompts that cross-examine a defendant's interrogatory answers against each other, witness tables with last-known contact information, and entity relationship maps across co-defendants.

The proving ground is one of the firm's biggest active matters: a severely injured client, three defendants, including a Seattle-area transit authority, and discovery that has already passed 200,000 pages with more coming. The case turns on what the transit authority knew about pedestrian hazards at its at-grade crossings, and the answer is buried in those productions: prior incident records, internal documents, and years of depositions. "We can ask Supio what a witness for that governmental entity testified to that supports our case, and it pulls those statements out and cites them in minutes—reviewing that deposition myself could take hours," Campbell Webster says. 

Williams, who manages the document set, estimates the team moves through that discovery in a quarter of the time it once took—fast enough to send meaningful follow-up discovery within days of a production that the defense expected to occupy GLP Attorneys for a month or two. The same speed has won races against the clock outright: facing a statute-of-limitations deadline on a major construction case, Williams used Supio to identify eight additional subcontractor defendants—correct legal names and service addresses—in minutes, and the lawsuit was filed that day.

The gains compound beyond the marquee cases. Pearson broke a stalled negotiation by asking Supio for every mental-health complaint in her client's records; it surfaced a pattern across 36 of 50 visits that the adjuster had dismissed, moving a $10,000 offer to the $100,000 policy limits. Westberg resolved a disputed double rear-end collision—a zero-dollar offer headed for litigation —by pulling every record of the second impact in five minutes, sparing her client a lawsuit entirely.

The hours that Supio has given back to the GLP Attorneys team land somewhere that matters.

"Instead of spending a Saturday afternoon pouring through records so I can be ready Monday, I'm at home playing Legos with my kids, or at the baseball game."
