FoundedN/A

Oxford Health Plans LLC provides health plans to employers and individuals in New York, New Jersey, and Connecticut. Founded in 1984, Oxford rose to prominence as a managed care provider in the tri-state area. In 2004, Oxford Health Plans was acquired by UnitedHealth Group (NYSE: UNH), one of the largest and most diversified health care companies in the United States. Today, Oxford Health Plans operate as a brand under UnitedHealthcare, continuing to offer a variety of health benefit plans, including traditional health maintenance organizations (HMOs), preferred provider organizations (PPOs), and consumer-directed health plans. While maintaining its strong regional brand recognition, its operations, technology, and network are integrated within the broader UnitedHealthcare and UnitedHealth Group structure.

Where Is Oxford Health Plans's Headquarters?

HQ Function

Historically served as the primary administrative and operational center for Oxford Health Plans. Post-acquisition by UnitedHealth Group in 2004, the facility's role likely transitioned to support regional UnitedHealthcare operations or other UHG business functions. Specific current use is not widely publicized.

Notable Features:

Specific notable architectural or facility highlights of the original Trumbull campus are not widely publicized, especially post-integration into UnitedHealth Group. It was a standard corporate office complex of its time, designed to support a large workforce.

Work Culture:

Prior to its acquisition, Oxford Health Plans was recognized for its dynamic growth and innovative, albeit sometimes aggressive, approach in the managed care sector. As part of UnitedHealth Group, any remaining operations at legacy sites would align with UHG's corporate culture, which emphasizes integrity, compassion, relationships, innovation, and performance.

HQ Significance:

The Trumbull site was highly significant as the nerve center of Oxford Health Plans during its rise to prominence as a leading health insurer in the New York, New Jersey, and Connecticut tri-state area. It represented a major player in the evolving healthcare landscape of the 1990s and early 2000s.

Values Reflected in HQ: Historically, the headquarters embodied Oxford's ambition and drive in the competitive health insurance market. Any current UHG presence would reflect UnitedHealth Group's broader mission of helping people live healthier lives and making the health system work better for everyone.

Location:

While Oxford Health Plans historically focused on the US Northeast (New York, New Jersey, Connecticut), as an integral part of UnitedHealth Group, it benefits from a vast global presence. UnitedHealth Group operates in all 50 U.S. states and in more than 130 other countries. Its services are delivered through two distinct platforms: UnitedHealthcare, which provides health care coverage and benefits services, and Optum, which provides information and technology-enabled health services. This global network supports diverse health care needs worldwide, from insurance coverage to pharmacy services and health technology solutions.
