Staffing Technical Services, Inc. STSI is a World Class Organization. As a Contract Employee and a Client (Hiring Manager) this is my go-to contract house to find qualified candidates that are well vetted for contract to hire, Direct Hire or just short-term contract. When a Candidate is presented you will not be wasting your time on a non-qualified candidate for your position(s). Their Back and Front office is very efficient in the onboarding process and can have candidates start in short period of time. From a Contract Employee stand point the onboarding process is relatively painless and straight forward.

STSI made the interviewing and onboarding process very easy, with an extremely professional and thorough process of acquiring personal data, resumes, job information, setting up interviews and keeping everyone in the process informed. They have also been active after the hire, checking in with me on a regular basis to make sure everything is going well and seeing if there is anything I need.
Highly recommend!

STSI is great! They are a very awesome group of professionals doing their very best for other professionals. My experience with this firm thus far has been top notch. The people are kind, curious, prompt and knowledgeable. I feel valued as an employee and that’s all I ask for. I would recommend them to any other professionals looking for a great firm.

I’ve worked through a lot of agencies over the years, and many have been unprofessional, unresponsive and have treated me like “just another number”. Not so with STSI. They worked hard to make sure I was happy, they treated me very well and even provided wonderful advice when I was offered a staff position rather than being upset that I was leaving them. Denise is very professional and, most importantly, she keeps to her word. I moved from Texas to Oregon for a position they matched me with and I had absolutely no issues.

I have worked contract for years, decades actually, and STSI is hands down the best company I have worked with in this manner. They are professional, thoughtful, and prompt. Every individual works so hard for each of their contract team member that you would swear they must actually be your employee. The team helped me with my contract and continued to stay in touch with me, something I never felt from any other company. I highly recommend STSI for contractors and companies looking for contract assistance with their projects.

My experience with STSI began several years ago when my job in Colorado ended. Within a few days, STSI had me employed again due to their professionalism, expertise and contacts. The professionals at STSI were committed to securing a better rate for me because of the knowledge I had gained in past years. Furthermore, my contact at STSI reaches out to make sure “all is well” at work and home.

Best recruiting service ever! Ryan Oliver was with me every step of the way. Even when he was on vacation he had his associate Julie Johnson step in for him and I was totally taken care of from the first phone call to the last email. Ryan, has just congratulated me on my Official Start Date at my new place and has let me know he will still be there for me as I join my new team of professionals! He has been hardcore perfect!

In today’s modern world of engineering, there are various fields that are fast pace, demanding and seek highly skilled & qualified professionals that are hard to find on their own sometimes, that’s where STSI and it’s highly skilled Talent Acquisition Professionals come into play! I’ve had the honor of knowing Ryan Oliver for a little over three years now and Ryan brought his A-GAME yet again. Ryan just hit another homerun for me with a great young engineering company that is growing by the week and I couldn’t be anymore pleased with the experience I’ve had both times working with Ryan and his colleagues at STSI.
