The 50 largest Medical Practices companies in New York State (2026 list)

The medical practices in New York State include large hospital systems and specialized care providers. Notable examples are ENT and Allergy Associates, offering comprehensive ear, nose, throat, allergy, and audiology care, and Schweiger Dermatology Group, which provides medical, cosmetic, and surgical dermatology services across 110 offices. Other significant practices include Crystal Run Health, a multi-specialty group focused on transforming healthcare delivery, and New York Cancer & Blood Specialists, a community oncology center. Many of these entities are well-established, with founding dates spanning several decades.

A recurring pattern among these companies is their focus on comprehensive, multi-specialty care, often integrating various medical services under one umbrella.

Another trend is the presence of large hospital networks like Vassar Brothers Medical Center, which provides integrated hospital and healthcare services in the Hudson Valley, and various branches of public hospital systems within New York City.

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 13, 2026.
