     o    The Idea of TVB - Vision of Frank Rowley


     o    Period of Organization and Raising Capital

     o    $3,100,000 Capitalization

     o    11 Directors

     o    Ace Cleaner's Location on Soscol Avenue



                       Within the first month, Kathi Metro

                       joined the team in the Credit area

                              and is still with us.



                              Times were trying...

                         Struggled first two and a half

                          years without a profit which

             tested the character of the organization....including

                         the survival of the 1986 flood!

               it was time to move our vision beyond Napa county.

                                to a new level.
