Founded in 1878, Ballinger was one of the first firms in the country to merge the disciplines of architecture and engineering into a professional practice.  Our single office in Philadelphia houses a staff of over 200, comprising three architectural studios, two multi-disciplinary engineering studios, and an interiors studio.  Ballinger has made interdisciplinary design excellence the centerpiece of our firm culture, and today, we are nationally recognized leaders in corporate, academic, research, and healthcare planning and design.  Building on a strong legacy of innovation, Ballinger is committed to the thoughtful integration of technology, a deep knowledge of our building types, and exceptional client service.
