HERBERT OLITSKY
PRESIDENT & FOUNDER
He gains his greatest professional satisfaction from helping clients solve complex problems and providing the highest levels of expertise. And part of that is always doing things with a human touch and the highest level of integrity.

RICHARD SINNREICH
CHIEF EXECUTIVE OFFICER
A current focus of his work is designing cloud based and on-premises system using tools such as Azure, MS 365 and AWS to solve real world problems, improve productivity and address new and complex business challenges. He always works closely with clients and works on minimizing the disruption and downtime of any migration. At the same time, he looks for way to visualize new processes and technologies and find new ways to use existing technologies. And he does all this while managing a team spanning the country and multiple regions internationally to meet customer needs.
After hours he relaxes by cooking outdoors, smoking meat and barbecuing.
