Since its beginning, A.D. Marble has fostered an environment that values the well-being of our employees. Without happy and motivated employees, we would not succeed. We are very proud to provide a workplace that values integrity, respect, and forward thinking.

At A.D. Marble, we understand the importance of balancing work and personal lives. Our culture provides flexibility that allows employees to dedicate time and energy to their families and personal commitments while serving A.D. Marble with the quality performance our clients have come to expect. Our team approach promotes input from everyone involved. We welcome ideas and solutions that make our work efficient while still challenging and enjoyable. The end goal is to meet our clients’ needs and keep our employees happy.

We also understand the importance of civic involvement and giving back to the community at large. We are currently dedicated to organizations such as the March of Dimes, Tookany-Tacony Frankford Watershed, Perkiomen Watershed, and PhilaBundance.

At A.D. Marble, we produce quality work for clients and provide benefits and atmosphere that support our employees’ wellness and long-term success.

Trail challenge!

It’s not surprising, given all the fieldwork we do, that A.D. Marble is populated by more than a few outdoor enthusiasts! Since 2019 we have taken to the trails in a friendly competition to explore and share new outdoor opportunities.


The 2022 Trail Challenge was our most competitive (and international) yet, with Team 2 winning by only 2 trails. Overall, staff hit 137 trails including locations in Iceland, Switzerland, and St. Martin.

In what has become an A.D. Marble tradition, our 2021 Trails Challenge saw record participation, with Team 3 ultimately winning with 99 trails visited. Overall, staff hit 214 trails in the Mid-Atlantic, New England, the Southeast regions.


To encourage staff to get outdoors (safely) during quarantine, we expanded to our own company-wide trail challenge! Staff was split into teams and asked to take photos at each trail they hiked, biked, ran, or walked. King of Prussia (Team 3) was the winner with 38 trails visited. 2020 was difficult for a multitude of reasons but getting outside was a great mood booster!


The trail challenge trend began in our King of Prussia office with the MontoCo Trail Challenge (https://www.montcopa.org/trailchallenge). It quickly became apparent that this was too good a thing to keep to one office.
