    • Thanks Tony, Everyone worked together as a team, including you! I still remember, you were the first person to teach me how to install a window before I became Skips helper. You were very good at training.

  1. Jim, I really enjoyed the presentation on Thermal and David Weis. You really hit the nail on the head by bringing out the characteristics that David had in creating and running the business. His relationships, his philosophy, his entrepreneurship and his leadership are apparent in the interviews. I am pleased with the whole picture that you created.
    Best wishes and Thank you,
    Eric Rascoe
