Paul is the only person we know who was a chef for 30 years and then made the leap to construction. At Silverback, he’s found that managing a kitchen and managing concrete are more similar than you might think. As he says, “Both are fast-paced and physically intense. Accomplishing the seemingly impossible in short order is business as usual. And every day, you see the fruits of your labor take shape.”

Along with Jonathan in Florida and Cameron in Virginia, Paul helps Silverback’s operational ship stay afloat. You’ll find him wearing multiple hats on any given day, from bookkeeping and HR to tech onboarding for our CDL drivers.

Matt learned the tricks of the project management trade at Universal Technical Institute of Technology (UTI/MMI). At Silverback Virginia, he estimates the cost of materials, labor and equipment for potential projects.

Similar to another Matt on our team, he doesn’t simply ship a bid and move on to the next set of numbers. Project management is the other half of Matt’s role. Clients can rest easy knowing he’ll stay involved and provide quality assurance until the last truck drives away.

Matt knows dirt. He went to school for it, with a Bachelor’s in Geology from UF as proof. Before joining Silverback, Matt worked in building materials distribution, touching every facet of the business from selling and preparing bids to creating new product programs, leading marketing and navigating relationships with high-level executives.

Matt’s dirt, rock and business knowledge come in handy when estimating jobs and matching our approach to the terrain. He helps close the gap between expectation and delivery by seeing projects through to the end, ensuring that our client’s dreams and drawings translate smoothly into cold concrete.
