Why Sterling

Company History

Sterling Engineering, Inc. and Sterling Staffing, Inc. are leading providers of Engineering Project Management and Technical Workforce solutions. Founded by Daniel Casey in 1969 with a commitment to providing clients with leading edge high speed equipment design services, Sterling was built on three major principles – Respect for clients, Commitment to Quality and Respect for Employees.


In 1997, after serving as VP of Danka Corporation, Dolores Connolly joined the Sterling family and became CEO. Under her leadership, Sterling has expanded its range of support services across all facets of their customers’ production needs. This strategy has fostered significant growth in business as well as provided accelerated career opportunities for our employees and leadership team.

With 45 years of industry experience,  Sterling is uniquely positioned to provide diverse solutions and build strong, lasting partnerships with customers in a variety of manufacturing-related industries.
