Great to do business with. I work for a GC, I was starting a new project and needed a job trailer. After searching and calling everywhere, I found Triumph Modular. They were the cheapest by far. Great customer service. They had my trailer onsite when expected. The trailer is nicely put together. Will be using them for future projects.
Lewis Zaj
Customer
Matt Dickinson and the Triumph team provided excellent services and a very high quality mobile showroom/office for our residential subdivision development project in NW PA. They mobilized quickly and went above and beyond to provide exceptional services in a timely manner, from identifying the right fit for us, to coordinating the delivery, and set up. I will work with Matt again on our upcoming projects, and I recommend his services based on the quality we received from Triumph Modular.
