Why OneSource
Clients trust us with their billing.
Candidates trust us with their licenses.
Staffing is a high-trust business. OneSource has spent 12 years building the credentialing infrastructure and compliance culture that lets both sides of every placement sleep soundly.
Every credential, verified.
Licenses, certifications, background checks, and exclusion screenings — completed before a candidate steps on-site. Not after.
Compliance at the center.
Our credentialing team is staffed by professionals who come from regulated industries. We know what documentation your facility actually needs.
Speed without shortcuts.
Emergency credentialing turnarounds available for urgent needs. We move fast — but we never skip a step.
One relationship, every vertical.
Healthcare, behavioral health, industrial, administrative, legal — managed through a single account team who knows your organization.
