History of OneOncology
- Founded: 2018
- Founders: OneOncology founding team
- Acquired by Cencora Inc.: 2023
OneOncology was founded in 2018 as a physician-led national platform dedicated to supporting independent community oncology practices. The company was created to help independent oncologists compete with larger healthcare systems while maintaining clinical autonomy and practice independence.
Throughout 2018-2022, OneOncology grew rapidly by partnering with independent oncology practices across the United States, providing practice management services, clinical support, and operational expertise. The company developed specialized capabilities in oncology practice management, clinical protocols, and patient support services.
In June 2023, Cencora (then AmerisourceBergen) and TPG completed their acquisition of a majority stake in OneOncology for $2.1 billion. This partnership positioned OneOncology to accelerate growth and expand its platform while maintaining its physician-led culture and commitment to independent oncology practices.
Following the acquisition, OneOncology continued to expand its network of affiliated practices and enhance its service offerings. The company focused on providing comprehensive support to independent oncology practices including practice management, clinical support, technology solutions, and pharmaceutical access.
In December 2025, Cencora announced a definitive agreement to acquire the remaining outstanding equity interests in OneOncology, further extending its solutions offering for community oncology and demonstrating its commitment to the oncology market.
