OSI is the oldest continuously operated business center under one ownership in the United States, having started under the corporation entitled Washington Office, Inc, in 1981.

The company was initially organized to provide Washington support services for out-of-town attorneys, by C. Jack Pearce. Pearce is an anti-trust attorney who served in the United States Department of Justice and the White House Office of Consumer Affairs , prior to entering private practice. It soon became clear that the support services were useful for Washington Area attorneys as well as attorneys from more outside the area.

Pearce’s next logical step was to invite firms of other types to use the office support systems. Today, OSI serves businesses of all types needing downtown temporary and shared office support, from start-ups to well established companies; small to substantial.

The 'Business Address' That Grew

Very often, OSI gets inquiries for just a ‘business address’. We are glad to oblige. We offer one of the best in the country. (K St, three blocks from the White House, with major subway lines crossing at Farragutt North).

But with OSI, you get much more than a “business address”. Every OSI service plan includes the right to use the offices on site as needed, paying only for the hour or hours used. Any incoming mail can be scanned, and emailed to you. If any person drops by to see you, you are immediately notified. You get documentation assisting your firm in getting a DC business license. You will have a customer portal enabling easy account administration. Using that portal, you can enter your business’s capabilities, and search out other OSI clients who may be able to provide you services and network with you.

And your service plan can grow, modified as your business needs change. You can add telephone service, of differing types. You can prepay office hours, getting an economy rate. You can grow your office on demand plan to full time, exclusive use officing. Every business plan we offer can be obtained on a month-to- month basis. So you can add and subtract services as needed.

With OSI, a ‘business address’ is a portal to a fully equipped business service center, configurable at will, as your office needs require, now and for years to come.

Virtual On-Demand Offices

Though the firm started as one of the first ‘virtual offices’, or on-demand offices, it has developed full time, exclusive use office capabilities, providing clients with growth paths. With the affiliation of Source Office Suites, OSI can also assist clients in arranging temporary shared and virtual office support throughout the Washington metropolitan area.

As business developed, OSI expanded its technical capacities. OSI provides sophisticated communication capacities, which integrate well with ‘mobile officing’, branch officing, home officing, and the more traditional forms of office operations.

The company has maintained its Farragut Square location, near the White House, throughout its history. Through steady growth and continuing attention to economical, efficient operation, OSI has come to offer a unique combination of services, with a central location in the Nation’s capitol.
