Gary M. "Mike" Williams - TTI President & Founder

Gary M. "Mike" Williams

President & Founder
A true veteran of the telecom industry, Mike Williams has been helping companies with their telemanagement challenges since the early days of de-regulation, when an influx of new providers and competition made the need for visibility and control more urgent than ever. Mike honed his experience at major providers, including MCI, and at The RTP Group, where he specialized in telecom consulting for major corporations throughout northern California.

After 25 years of working and consulting in telecom, IT, expense management, and procurement, Mike co-founded TeleManagement Technologies, Inc. "TTI" in 1996. His vision was to provide a level of customer collaboration and support that would create a tight, closed loop relationship between the users, the support team and the developers. Today, TTI's strong reputation for unparalleled service and customer-driven solutions is the result.

Mike continues to play an active role in product development and customer service and the company has thrived and grown through his friendly, accessible 'hands on' management style.

"At TTI we try to never lose sight of the growing challenges of our user community. That's why we continue to blend the latest in telemanagement innovation with old fashioned customer service. It's the formula which got us where we are today, and one we plan to continue for years to come."
Gary M. "Mike" Williams
