Provides high quality, outsourced engineering, information technology, and professional personnel to a wide range of clients on the West Coast.

Founded in 1995, by Ron & June Stein, Principal Technical Services (PTS) was designed to meet a gap in the market. Client organizations were seeking greater transparency and flexibility as they contracted specialized talent to augment key roles in their organizations. As a project manager in the industry, Ron knew first-hand that success relied upon attracting and retaining great candidates with a full compensation package, including PTO and medical benefits – an approach not common for typical engineering staffing services in the 90’s. Our team subsequently delivered a best-in-class service to both the client and candidate and are the premier contingent workforce management partner for the California Energy & Infrastructure market.

Now known as PTS Advance, we are building on past success and expanding the quality of service we offer to clients and candidates in new geographies and industries.

It is always about more than a transaction. We are committed to growing with you. We believe that by reimagining the way we work as a team with our customers, we can advance the systems and combinations of talent that ultimately drive cost, quality, safety, and effectiveness of new projects and operations in your industry.

We help optimize human capital. We do more than just fill a position. We work hard to understand your changing needs and requirements so that we can make a valuable contribution to your career, company, or industry.

We are honest and transparent in the process because we put you first.

We are PTS Advance. Teamwork Reimagined
