“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.”
