# List of healthcare providers in Oklahoma

Tamtam tracks 57 healthcare providers headquartered in Oklahoma. This list ranks the 50 largest by number of employees on LinkedIn, led by INTEGRIS Health, Saint Francis Health System and The Chickasaw Nation. Their median headcount is 466. Half of them were founded in 1978 or later. The most common headquarters are Oklahoma City (14) and Tulsa (14).

These are the largest healthcare providers in Oklahoma. The list includes a mix of large integrated health systems, specialized hospitals, and government entities involved in health services. Companies like INTEGRIS Health, founded in 1994, offer comprehensive statewide services, while Saint Francis Health System, established in 1960, provides extensive care through multiple facilities in Tulsa. OU Health is a comprehensive academic health system, and Oklahoma Heart Hospital focuses on specialized cardiac care.

A notable pattern is the concentration of major healthcare organizations in Oklahoma City and Tulsa. Many of these providers, such as Norman Regional Health System (founded 1946) and Comanche County Memorial Hospital (founded 1948), have long histories, indicating established healthcare infrastructure in the state. The presence of entities like The Chickasaw Nation and Cherokee Nation highlights their role in providing health and community services.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
