Ascension Tech Stack

Large Catholic health system operating 90+ hospitals across 17 states

Hospitals and Health Care St. Louis, MO 10,001+ employees Nonprofit

Ascension is a nonprofit health system with nearly 100,000 associates managing 90 wholly owned hospitals plus equity interests in 29 others across 17 states and DC. The tech stack reveals a transitional enterprise: legacy clinical systems (Cerner, Epic, Athena, Allscripts, Meditech) paired with modern web development (React, Next.js, TypeScript, GraphQL) and an aggressive cloud migration underway (adopting Azure, GCP, Terraform, Ansible). The hiring surge (846 roles in 30 days, accelerating) is heavily weighted toward clinical staff (healthcare 1203, pharmacy 33, emergency 22) with a secondary but visible security group (40 open roles), signaling both operational scaling and heightened compliance focus.
