"William has a very broad knowledge of the industry, its market participants, their product offerings and their compatibility. He also has deep knowledge of systems and related research, development and support processes. He differentiates himself from a pure “techie” by also having a strong grasp of the strategic “big picture.” He provided valuable strategic input to our business plan, alternative scenario planning, and financial sensitivity analyses, and was instrumental in answering investor questions. He is a team player and I would welcome the opportunity to work with William again."
— Charles Garber, President & CEO at Garber Associates

"William was the primary mover for CoSine's SPF, H.323 and other firewall and packet filtering initiatives for CoSines's product line. All of this was a stunningly difficult feature set to pull off (especially if you know about CoSine's platform) and not only was William one of the most technically astute people I've ever met in this field, he is also easy to work with and a pleasant colleague. I recommend William highly both as a manager and as a team player."
