PS&S has announced four new hires, including a new head of its building services group and three additions to its land services team.

The Warren-based architecture, engineering and environmental consulting firm said Monday that Harry “Ted” Osborne has joined its senior management committee as senior director of the company’s building services group. Meantime, Steven Ewing, Russell Cipolla and Bill Schneider have joined the company as senior directors.

“Ted, Russell, Steve and Bill bring tremendous knowledge, skills and experiences from successful organizations across multiple sectors,” said John Sartor, CEO and president of PS&S. “These key hires exemplify our commitment to be the best partner and support our clients strategically with innovation, technical excellence and unparalleled integrity using the most knowledgeable experts in the industry.”

Osborne, who will be based in the Warren office, brings 40 years of architectural design and planning experience to the building services group, according to a news release. Working with the land services group, the team will continue to serve clients across all aspects of design and engineering, including civil engineering, permitting and survey work.

PS&S said Osborne’s involvement in architectural design encompasses significant domestic and international expertise, with clients including Fortune 500 companies. His prior work includes architectural design and engineering solutions for pharmaceutical manufacturing plants, research and development labs, urban redevelopment programs, corporate headquarters buildings, health care and education.

He has also served as a project principal, developing infrastructure protection measures due to damage from Hurricane Sandy, the news release said. Osborne joins the firm from Gannett Fleming and reports to Sartor.

Ewing, Cipolla and Schneider will report to Joseph Fleming, first executive vice president of the PS&S land services group.

Cipolla, who is based in the firm’s Cherry Hill office, will head up a new bridges and roads division in the land services group.
