Each day, United Personnel connects more than 700 people with great jobs throughout Western Massachusetts and beyond. From temporary and contract work to direct hire placement, we provide clients with staffing solutions in a variety of industries and fields, including:

For more than 30 years, United Personnel has developed a deep knowledge of the local employment market. Our close partnerships with some of the area’s largest employers, as well as smaller local businesses, result in great matches for employers and candidates alike.


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
