About US

Our Vision

D2i was founded by Dan and Naomi D’Antonio in 2022 with a simple but powerful vision, to build an engineering firm that delivers better service for clients and a better workplace for employees. After years of experience in the industry, Dan and Naomi saw an opportunity to create something different a company built on excellence, integrity, and care. They believed that when engineers are empowered, supported, and truly enjoy their work, clients feel the difference. Today, D2i brings that vision to life through exceptional customer care, dedicated project delivery, and a positive, people-first culture. From a beautiful office in downtown Tampa, our team proudly serves clients across the entire state of Florida, providing innovative, high-quality infrastructure solutions. As a Small Business Certified firm with FDOT prequalifications in Work Groups 3, 6, 7, and 13, D2i combines technical expertise with genuine partnership. Every project we take on is guided by our commitment to raising the bar for both client service and employee experience.
