Company Description

At OST, we’re a bit like what you may call a machine, but with a more human touch. Day in and day out for the last 27 years we’ve been more than just a staffing company. Throughout this time we’ve built relationships, we’ve grown together internally and externally, and have created a system that allows us to personally cater to the needs of our clients and candidates. As we celebrate this occasion, it important to note that for us, 27 years is more than just a number or an anniversary. It is 27 years of relationships, 27 years of trust, and 27 years of total reliability. We’ve been a mentor for some, a team builder for others, but most importantly we’ve been there. We know there is no substitute for experience, so let us help you navigate through the ever changing web of talent.

Operating in a crowded marketplace, we have succeeded by staying ahead of the curve. No two projects are the same, and neither are our solutions. We’ve got the connections. We know the people. We have the opportunities. How soon can you start?
