Our Story

In July 2017, two leaders in the education staffing industry combined forces. Education Solutions Services (ESS) of Tennessee brought an extensive leadership team consisting of experts who have dedicated their careers to serving the K-12 marketplace. Source4Teachers/MissionOne of New Jersey brought 18 years of experience in providing exceptional substitute staffing services to school districts. This successful combination was further enhanced through the strategic acquisitions of EMS SubDesk of Oregon, SubTeachUSA of Arkansas, and PCMI willSub® of Michigan.


With 35+ years of business expertise, Buddy Helton, the President and CEO of ESS, has a proven history of driving growth and enhancing customer satisfaction in every organization he’s led.
