These Phoenix-based organizations are predominantly large healthcare providers, ranging from extensive hospital systems to specialized care centers. Many are long-established institutions, with some founded in the late 19th century.
Key entities include Banner Health, a nonprofit healthcare system operating across six states, and Phoenix Children's, a pediatric health system offering comprehensive care. St. Joseph's Hospital and Medical Center provides specialized services in neurology and cardiology, while Valleywise Health has served Maricopa County for over 140 years. Sonora Quest Laboratories performs millions of diagnostic tests annually, and Hospice of the Valley focuses on end-of-life care. A notable pattern is the dominance of healthcare services, with many organizations providing a broad spectrum of medical and support services.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
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 11, 2026.
