In 1984, Mary Ellen Scott and her late husband, Jay Canavan, launched United Personnel, a staffing company with deep roots in the Pioneer Valley. The company was soon recognized as a source of staffing and employment solutions for scores of local companies and thousands of employees.

Thirty years after its founding, Mary Ellen and Jay Canavan’s daughter Tricia leads the company as president, while her sister Andrea retains a position on the company’s board. Mary Ellen continues to serve as chairman emerita.

Realizing that excellence means different things to different people, it is always our objective to:

  • Provide great opportunities to all of our candidates, matching their skills, aspirations, and cultural and scheduling preferences with jobs they’ll love.  
  • Partner with clients to improve all aspects of human resource management, including training, retention, compliance, and efficiency
  • Identify and place highly skilled candidates with the area’s top employers

Headquartered in downtown Springfield, United Personnel offers staffing support services throughout Massachusetts and Connecticut. Additional offices are located in Northampton, MA, Pittsfield, MA, Chelmsford, MA, Hartford, CT and New Haven, CT.

Our goal is to be an inclusive workforce that is representative, at all job levels, of the communities we serve.
