 Paolo M. Vianson, CEO    pvianson@durendal-llc.com

Paolo got his "Dottore in Ingegnieria Maccanica" degree from the Polytechnic of Milano, Italy, in 1983.

In 1984 Paolo moved to the San Francisco Bay Area where he joined Square D Company in charge of all R&D and Manufacturing activities. Between 1984 and 1990 Paolo and his Team developed several advanced products in the high voltage switching market, using a patented high-power mechanism. Square D Co. was able to penetrate the European market with a product that was superior in performance and, at the same time, more compact.

In 1990, Paolo and a partner started PMC Technology, Inc., a company that designed and manufactured customized products for OEMs in the international medium voltage power transmission and distribution market. Paolo leveraged his electro-mechanical know-how to develop a second patented operating mechanism that enabled PMC Technology to manufacture the most compact circuit breakers in the medium voltage market. Operating as a Lean Enterprise, PMC Technology developed and manufactured customized products in half the time usually required in the industry. Under Paolo's management, PMC Technology rapidly became profitable.

In 1994, Paolo and his partner sold PMC Technology Inc to Powell Industries Inc (POWL). Paolo was retained as Vice President and General Manager of the newly formed subsidiary. With the new financial support, Paolo was able to grow the subsidiary's business three fold and develop new, more powerful and profitable lines of products for the North America and Asian Markets.

In 2000, Paolo and his family moved to Arizona and switched his career to Investment Services. Since then, Paolo has acquired ownership interest in several companies with unique growth potential in a variety of market segments and uses his knowledge in Lean Enterprises transformation to provide critical support.
