These include a business address, mail and courier services, phone answering, internet access, and other administrative services as needed. All of these are available individually or in combination, with transparent pricing for each service or package. Our office plans, starting at an accessible $35 per month, are designed with the needs of emerging counselors in mind.

"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.”
