Marc G.

As CEO of TDG Transit Design Group, I lead a multidisciplinary team across six countries and three continents focused on designing, engineering, and delivering innovative, reliable, and sustainable green tech solutions for the rail, transportation, and national security sectors. TDG operates at the intersection of engineering, design, and technology, supporting complex programs with integrated lighting systems built on advanced solid-state lighting technologies, custom exterior headlight, marker, and signature systems, firmware- and software-based smart controls, emergency and egress systems, UV-based microbial reduction solutions, proprietary and patented technologies, testing expertise, and advanced R&D. Our work is grounded in practical problem-solving — turning ambitious ideas into solutions that perform in the real world. I’m passionate about building organizations where technical excellence, accountability, and curiosity go hand in hand. Whether advancing green technology, developing patented solutions, strengthening delivery processes, or growing future leaders, my focus is on creating long-term value for our clients, partners, and communities. At TDG, we believe innovation isn’t just about what’s possible — it’s about what’s useful, scalable, and sustainable.
