3 min read

Thorne Research, now known as Thorne, operates a split corporate structure with two key locations serving different functions. While the company's corporate headquarters is in New York City, all manufacturing and distribution are handled from a separate, larger facility in Summerville, South Carolina. This dual-location model ensures administrative functions are separated from the production and logistics process.

Quick Summary

Thorne has two primary locations: a corporate office in New York City and a manufacturing and distribution facility in Summerville, South Carolina. This setup divides the company's administrative and operational responsibilities for efficient management of its health supplement business.

Key Points

New York City Headquarters: Thorne's corporate office is located at 152 West 57th Street, where executive decisions and brand strategy are managed.
Summerville, SC Manufacturing: The company's extensive manufacturing and distribution operations are based in Summerville, South Carolina.
Decades of Relocations: Thorne's location has evolved over time, with prior headquarters in Seattle, WA, and Sandpoint, ID.
Manufacturing Expansion: The Summerville campus was significantly expanded in 2023 to over 540,000 square feet to support increased production.
Split Operations Strategy: Thorne separates corporate oversight (NY) from physical production (SC) to optimize both administrative and manufacturing processes.
Vertical Integration: The South Carolina facility allows Thorne to vertically integrate its manufacturing, ensuring complete control over quality and sourcing.

Understanding Thorne's Dual Location Strategy

Thorne, a leading manufacturer of health and wellness products, has a geographically diverse operational structure that has evolved over decades. For customers and partners, understanding where is Thorne Research located is key to knowing where different parts of the business are managed. The company's operations are divided between a corporate headquarters in New York City and a state-of-the-art manufacturing campus in Summerville, South Carolina. This separation allows for a focus on corporate strategy and investment in a major business hub while centralizing the complex manufacturing and logistics processes in a dedicated production facility.

The Corporate Heartbeat: New York City

Thorne's corporate headquarters is situated in the heart of New York City. This location is the central hub for the company's high-level strategy, business development, marketing, and investor relations. It is where Thorne's executives and corporate teams manage partnerships, brand strategy, and the overall business direction. The New York office is a reflection of the company's evolution from a practitioner-focused supplement provider to a broader, direct-to-consumer health technology company.

The Manufacturing Powerhouse: Summerville, South Carolina

In stark contrast to its corporate hub, Thorne's manufacturing, distribution, and research and development operations are concentrated in Summerville, South Carolina. This facility is where Thorne's nutritional supplements are produced, tested, and shipped to customers and partners worldwide. The company has invested heavily in this location, expanding its manufacturing campus to over 540,000 square feet by 2023. This significant investment underscores Thorne's commitment to vertical integration and control over its product quality and supply chain.

Thorne's Geographical Evolution

Thorne's current two-location model is the result of a series of strategic moves throughout its history. The company was founded in Seattle, Washington, in 1984 before moving its headquarters to Sandpoint, Idaho, in 1990. For many years, Idaho was the primary base of operations. The major shift to South Carolina for manufacturing and the eventual establishment of a corporate office in New York solidified the company's modern structure.

Thorne's Relocation Milestones:

1984: Founded in Seattle, Washington.
1990: Moved headquarters to Sandpoint, Idaho.
2018: Relocated manufacturing and new corporate headquarters to Summerville, South Carolina.
Present: Maintains split operations with corporate in New York and manufacturing in South Carolina.
