This list ranks the 50 largest by number of employees on LinkedIn, led by Doctor, ENT and Allergy Associates and Schweiger Dermatology Group. Their median headcount is 215. The most common headquarters are New York (16), Brooklyn (4) and Albany (3).

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.

## 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.
