Though founded over 40 years ago specifically for attorneys, OSI has evolved to be the most technically advanced officing system in the area, tailored to attorney needs, while continuing to be the best value option.
With OSI, an attorney can
  • Have immediate information on any contact with her or his office -- whether by mail or package receipt (scan and email notification), mail contents (opening and scanning upon authorization), telephone call receipt (live answer and relay, or automatic call relay, or voice mail notification with immediate email of text and audio file), or client or other visitor appearance at the office (call or email notification from the reception area.)
  • Use the most advanced account administration portal system in the area -- enabling the attorney to reserve offices; view billing statements; pay bills online; obtain office use records (including records of telephone calls, office uses, payments, copies and printing, and other records); question OSI staff on any matter of interest; adjust/update her/his client records; and issue instructions to OSI staff as needed.
  • Publish qualifications to over 1000 other attorney and non attorney clients of OSI
  • Network with other attorneys and other professionals, by using the Portal and OSI events to obtain information on available legal and other specialties;
  • Have office access from 8 AM to 9 PM weekdays and 9 AM to 6 PM Saturdays
  • Have access to OSI’s Fly-by computer bar when in the office
  • Participate in special events for OSI and other attorneys.

OSI’s K street address has the K street cachet -- there is no better address in town (except perhaps the White House)

OSI’s Officing system is the most flexible in the area. Check out the options on the pricing and packages page on this site. From just an address, or just occasional office use, or just a phone number with multiple use options, through a variety of package options, up to and including full time exclusive use offices, all on a month to month basis, modifiable with a call or email, OSI provides you all the flexibility your practice may need to accommodate and any configuration it may require in changing circumstances.

The OSI K Street suite is fully equipped for your use. We have an highly presentable reception area, an experienced and professional reception staff and Operations Manager on site, a privacy-protecting client check-in kiosk, high speed internet, no-charge on site telephone use, a variety of office sizes, two conference rooms, and an advanced copy, computer, and mail service area. You can walk in and work, conference, network internally and externally, print and copy as needed, and function as fully as you could in a private office of your own at any location.

And we make it all so easy. You can inquire about our services by phone, email, web inquiry, or an office visit, as you choose. You can register on-line, by emailed copy of the one page service contract, by phone, or by office visit.
