TriStaff is a San Marcos staffing agency proudly supporting North County businesses and job seekers with localized expertise and a personal touch. Since 1971, TriStaff has helped connect great companies with skilled professionals across Southern California. Our San Marcos office plays a key role in expanding that reach—offering tailored staffing solutions for industries like manufacturing, healthcare, finance, technology, and administrative services.

Located in the heart of North County, our San Marcos staffing agency understands the unique hiring needs of this growing region. Whether you’re a business looking to fill key positions or a job seeker exploring new opportunities, our experienced recruiters are here to help. We focus on long-term partnerships built on trust, local market insight, and a commitment to finding the right fit—for both employers and candidates.

In November 2023, TriStaff’s temporary staffing divisions were acquired by Amtec, a well-established staffing firm with over 65 years of experience. This partnership has strengthened our ability to serve clients throughout the region while maintaining the personal, hands-on service we’re known for. Today, TriStaff’s San Marcos office works closely with our San Diego office, giving clients access to a wider talent network and additional recruiting support.

Together, our two offices allow us to serve both central San Diego and North County with flexibility, agility, and deep industry knowledge. Whether you’re hiring for a single role or building out an entire team, TriStaff offers the tools, insight, and experience to help you succeed.
