  • ~ Makes the “light bulb” turn on

    "“Theo is outstanding! After a 15 minute discussion Theo was able to shore up five tech issues I was having. He immediately enabled me to be functional in critical areas which made me more productive during the work day.  He is an outstanding resource for attaining higher task maturity levels in the Microsoft space, in all telecom issues and is an expert in video conferencing technology.”
