Founded in 1999, ESI was built on a simple idea: take care of people and deliver exceptional service. What began as a specialized staffing partner has grown into a comprehensive workforce solutions provider serving hundreds of organizations — and expanding.

For more than 25 years, we’ve supported clients with innovative workforce solutions, including Encore (formerly RetireRehire) our return-to-work program and SubSource, our substitute staffing program. Today, we are focused on growing and evolving our staffing solutions to meet the changing needs of organizations nationwide.

Expanding Our Workforce Solutions

InDemand delivers traditional staffing services designed to help organizations quickly and effectively fill critical roles with qualified talent.

ESI Connect, our Managed Service Provider (MSP) solution, provides scalable workforce management, vendor coordination, compliance oversight, and reporting — giving organizations a streamlined, strategic approach to contingent staffing.

Together, these programs allow us to support clients at every stage of workforce planning — from individual placements to full program management.

Built on Service

Our experienced teams in employee services, human resources, payroll, billing, and client management are dedicated to delivering responsive, personalized support. We serve both our clients and our employees with professionalism, integrity, and care.

We understand that strong organizations are built on strong people. That’s why we are committed to creating positive experiences for the employees we place and the clients we partner with.

For job seekers, ESI offers meaningful opportunities, dependable support, and a team that values your skills and contributions. We work to match talented professionals with organizations where they can succeed and grow. We are dedicated to creating positive experiences and long-term success for our employees, no matter which ESI program you join.

Looking Ahead

As we continue to expand our services and reach, our focus remains the same: deliver trusted workforce solutions, build lasting partnerships, and create opportunities for people and organizations to thrive.

Our Mission

With integrity and heart, we support and serve those who educate and strengthen our communities.
