# The 30 largest healthcare providers in Utrecht

Tamtam tracks 30 healthcare providers headquartered in Utrecht. This list ranks all of them by number of employees on LinkedIn, led by UMC Utrecht, Koninklijke Kentalis and Careyn. Their median headcount is 595. Half of them were founded in 1992 or later.

These Utrecht-based companies are primarily large healthcare providers, including hospitals and specialized care facilities. UMC Utrecht, founded in 1817, is an academic healthcare institution, while Koninklijke Kentalis focuses on individuals with hearing and communication impairments. Prinses Máxima Centrum voor kinderoncologie specializes in pediatric cancer. Mental health support is offered by Altrecht and Bij Lister ga je verder, and ArboNed BV assists SMBs with employee health.

Most of these organizations are large, with UMC Utrecht employing over 10,000 people. A notable pattern is the strong presence of long-established institutions, with several founded in the 19th and early 20th centuries, such as UMC Utrecht (1817), Diakonessenhuis (1844), and Wilhelmina Kinderziekenhuis (1888). This indicates a mature and well-developed healthcare infrastructure in Utrecht.

## 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.
