Thomas P. Otten has been involved in construction and had a knack for mechanical things from his beginnings at a very early age.  His inspiration for entering Engineering was his fascination with the workings of early Porsche and VW automobiles.


Design means to me that every designing engineer has the opportunity to become at some stage an artist… that every craftsman who can do more than what he is trained to do is an artist.  – F.A. Porsche
