Software that extends
human expertise.

Digital Extensions was founded by Kent Merrell. He was a paramedic before he was an engineer — first an EMT with the volunteer fire department in Cave Junction, Oregon, then paramedicine at BYU-Idaho, hospital rotations at EIRMC, a summer at Grady, and two years running calls with North Country EMS near Mount St. Helens. Those were years spent writing the kind of timestamped record an attorney reads later, and they left a durable respect for records that can be traced, checked, and understood by someone who wasn't there.

Then roughly thirty years of enterprise software — healthcare claims and reporting systems at Ingenix / UnitedHealth Group, platform and documentation work for NIH/NIAID. Years on the charting side of clinical documentation, followed by years on the tooling side of it.

Those two halves meet in the sourced chronology: a medical-record chronology where every entry carries its exact source, so any reader can get from the event back to the supporting page without a hunt. The method comes first — it can be kept by hand in a document or a spreadsheet. Corpus Chronology exists to make the discipline easier to keep: gather the record set, read with the cite attached, mark the events that matter, see the shape of treatment, and export something that traces back.

The boundary is worth stating plainly. Kent is not a nurse and has not worked the legal side of a case. He builds the tools and teaches the provenance discipline; the nursing and legal-practice judgment stays with the professionals using them.
