Ballinger completed a campus-wide master plan for New York Presbyterian Hospital which resulted in a six-year, phased expansion and renovation plan. To begin plan implementation, Ballinger designed two major projects - the Advanced Therapeutic Services Center and the vertical expansion of the Greenberg Pavilion. The Advanced Therapeutic Services Center is an infill building which houses high-tech diagnostics including operating rooms, interventional radiology, expansion of radiation oncology, expansion of the Emergency Department, and a blood bank/stem cell program. The Greenberg Pavilion’s expansion dramatically increases the hospital’s bed capacity.
