Karl Volkman - Chief Technical Officer, Principal


Karl Volkman is the Chief Technical Officer and a principal of SRV Network, Incorporated. He was SRV’s first fulltime employee even before the incorporation papers were finalized. Karl brings a diverse technical background to the table and SRV’s customers appreciate his vast knowledge and unique perspectives on best utilizing technology in their businesses. Initially, Karl was a high school teacher giving instruction in mathematics, computers, and science at a private school while coaching a variety of sports. When wedding bells started ringing, a slight shifting of career focus occurred and Karl became a programmer at a financial institution, John Nuveen and Company, (currently known as Nuveen Investments). During his long tenure at John Nuveen, he moved over into technical support of the minicomputers, communications equipment, phone systems, and this funny little, new invention called the personal computer.

When Karl left John Nuveen, he was overseeing the technical support department responsible for all technology at every location across the country. Karl’s next stop was The Habitat Company where he directed all of Information Technology (IT). While at The Habitat Company, Karl formed and fermented the plan that became SRV Network, Incorporated. Over the past 21 years, Karl has worn many hats for customers ranging from the lead technician during all technical crises, to lead UNIX support throughout a multiyear implementation of Oracle financials at the Chicago Public Schools, to the director of technology for New Lenox School District 161. Karl resides in Flossmoor, IL with his wife Therese and they are proud parents of two adult daughters.
