Day & Zimmermann, a leading national provider of products and outsourcing solutions for government and commercial customers, today announced that it will move its Philadelphia-based global headquarters from 1818 Market Street to the newly renovated and refurbished 1500 Spring Garden Street office complex. With 325 employees occupying 122,000 square feet on four floors, the offices will feature state-of-the-art computer training rooms, video conferencing capabilities, flexible work stations, sound-dampening technology, and more. Among Day & Zimmermann’s new neighbors at the building: CBS3, Independence Blue Cross, and North American Publishing Co.

“With this move, we have the opportunity to design modern, innovative offices that reflect Day & Zimmermann’s forward-thinking business focus,” says Hal Yoh, President and CEO of Day & Zimmermann. “Our surroundings will give our employees a comfortable, yet professional environment to continue and enhance the excellent services they offer to our customers each day. We are excited to take this next step in our company’s long and successful history, and become part of the significant growth and development in Philadelphia’s Spring Garden section.”
