About
Radiology Partners is the largest physician-owned and physician-led radiology practice in the United States, founded in 2012 by Rich Whitney and Scott Seidelmann and headquartered in El Segundo, California. The company partners with hospitals, health systems, outpatient imaging centers, and specialty practices to deliver comprehensive diagnostic and interventional radiology services. Unlike corporate radiology groups that are investor-owned, Radiology Partners is structured to keep radiologists in ownership and governance positions, a model the company uses to attract and retain talent in a specialty facing significant workforce shortages.
Epic holds over 42% of U.S. acute care hospital EHR market share and is embedding AI across 150+ clinical workflows for 2026, while facing antitrust scrutiny.
