Office Space For Mental Health Professionals

Serving more than 150 professionals with affordable practice opportunities.

Washington D.C. temporary, shared, and on demand office space for Mental Health Professionals

OSI now supports over 150 mental health professionals at its K Street location in the heart of the Washington metropolitan area.

OSI provides office space for mental health professionals as needed at $14 per hour, from 8:30 AM till 9:00 PM on weekdays, and 9 AM till 6 PM on Saturdays. One can arrange regular schedules, with chosen offices, reserved for specific times. The mental health professional is charged for offices reserved and used, and not a cent more. Arrangements are month to month, with no term commitments.

In addition to providing hourly, daily, weekly and exclusive office services, OSI offers an array of related services. Clients can have a business address, mailing and messenger services, phone answering, Internet access, and other office services as needed, sepa rately or in combination with clear pricing for each service or combination of services. Office plans start at $35 per month for counselors beginning their practices.

We Serve Many Mental Health Professionals Because:
  • OSI’s location places therapists close to a large, diverse population with expansive business hours; meaning that clients can easily schedule the early morning, lunch, or after work sessions that are always in demand.
  • OSI can also serve as a cost effective second office, thereby boosting your chances of being accepted onto the most desirable insurance panels, significantly increasing your client scope.
  • OSI office spaces can be reconfigured to allow individual and couples therapy or assessments/testing. The conference room can be used to host small workshops (which is a great strategy for building a reputation).
  • We facilitate networking among OSI therapists through a variety of means, which will help you construct a professional presence and form referral sources.
  • OSI allows you to immediately secure a professional address at minimal cost, thereby allowing professionals to apply to insurance panels. Partners will have access to a professional receptionist as well as a mailing address for your correspondence; paying for the time you actually use.
Our virtual, shared and temporary on-demand office network provides scalability over a wide range of office uses. If your practice requires full time office needs, we will provide full time, dedicated office use at 1629 K st. suite 300, or at 1627 K st. Suites 400 and 500.

"OSI has been instrumental in building my psychology practice for nearly 10 years. I started with hourly office use; graduated to a shared office space; and for the past few years have my own private full-time office. The quality and array of services along with the flexibility of plans are invaluable."
Diane Kern, Ph.D. Licensed Psychologist
“I retired from my full time solo private practice as a psychologist but wanted to have office hours on a part time basis. OSI and I worked out an office service plan that fit my needs perfectly, at a very reasonable cost. I have been a very satisfied customer with their services and would recommend OSI to anyone needing part time or permanent office services.”
