"T-REX's name comes from our first location, the Railway Exchange. When Downtown STL, the Regional Chamber and City of St. Louis came together to form the Technology Entrepreneur Center (T.E.C.) they made their first home at the Old Railway Exchange on Olive. Put them together: TEC + Railway Ex = T-REX!"
