About Us

Educational Services LLC. (ESI) is the leading provider of employee staffing solutions for school districts, municipalities, and public service agencies serving Arizona.


Founded in 1999 by three Arizona educators, we have a passion for helping people and making a positive impact in our community.

We're proud to be operating locally for over 25 years as a family-owned business. In fact, we consider our team and the employees we serve to be our ESI family.

At our inception, we developed Arizona’s premier return-to-work program known as RetireRehire, and since then, SubSource, the largest substitute staffing program in the state.

We have experienced and dedicated employee service, human resource, payroll, billing, and client management teams that compassionately serve our clients and employees.  Over the past 25 years, we have successfully supported over 300 clients throughout every corner of Arizona.

Our team derives its strength from the breadth of experience comprised in the company leadership, which includes education and business leaders from the community. We approach our client’s needs with a thorough understanding of the broad objectives and impacts sought by each unique organization.

We are equally dedicated to both exceptional client service and employee service with a proven track record of immediate, personal response. The employees we serve deserve the utmost of respect and superlative care to honor their special contributions to our community. 

Our well-earned reputation is built on a foundation of trust, responsiveness, and partnership. These values are further demonstrated in our active support of education foundations, professional education associations, and community programs, such as Local First Arizona and Conscious Capitalism.

Our mission statement: With integrity and heart, we support and serve those who educate and serve our community.
