We are headquartered in the eclectic and historic Deep Ellum neighborhood of Dallas, Texas, less than one mile from downtown in a light-filled, fully renovated, gigabit fiber connected, exposed wood and steel-framed warehouse. The building was the original home of National Welding and Grinding Company and is owned by our CEO's family -- so it really is our home.
