Delta didn’t release any financial terms of its acquisition agreement. Previously based in Phoenix in Oswego County, TES staff members have moved to a new Delta office at 6700 Thompson Road, Suite 1 in DeWitt.

Delta Engineers, Architects & Land Surveyors, DPC (Delta) is an architectural, engineering, and professional services firm based in Endwell, near Binghamton.

TES ecological services will “expand the existing portfolio of Delta and enhance the breadth of consulting expertise” available to the client rosters of each firm, Delta said.

In the deal, Delta adds TES’s six employees, increasing the Delta employee count to 150, Kim Collavo, marketing manager at Delta, tells CNYBJ in an email. The firm operates four offices in New York and one in Maryland.
