William Mooney
As President and CEO of Synergex, Bill provides strategy and direction in all functional areas of the company, including our flagship product suite, Synergy/DE, which has evolved over the past 30 years from a cross-platform business language to an extensive suite of object-oriented development tools that rivals any popular toolset today. Bill has built close partner relationships with our customers in a wide range of industries and has guided them to reduce their software investment, increase profitability, and succeed in varied market conditions.
Bill was selected to participate in Leadership Sacramento, a program of the Sacramento Metro Chamber Foundation, where he worked to improve business and the regional community.
