D&Z Gives Back


At Day & Zimmermann, integrity isn’t an afterthought. It’s a core component of our culture—a key piece of what we’ve provided to our clients for more than 120 years. We strive to bring out the best in our people–not just in the work they provide our clients, but what they can do for their local communities. Because of the unique structure of our organization, we are able to help our employees support various causes in communities across the country.

Supporting Communities in Need

We’re passionate about giving back to our communities. We support education from early childhood through secondary, and have supported initiatives promoting science, technology, engineering and math (STEM) for students. Additionally, we have donated our time and resources toward causes that assist underprivileged children, health and wellness as well as support for our U.S. Veterans.

Our efforts support our core values of Safety, Integrity, Diversity and Success and are evaluated by our actions, at work, within the community and in life.


D&Z is a Job Partner for the Work-Study Program at Cristo Rey Philadelphia enabling talented students from limited-income backgrounds with an education and invaluable work experience.
