Edward Karl | CPA | CEO

Ed Karl’s 30-plus years of broad-based management experience ranges from ownership of a start-up business to President and CEO of a large diversified holding company. Additionally, he has an extensive record of success in the acquisition and sale of companies as well as corporate restructuring, mergers, downsizing, tender offers and financing/refinancing.

Seeing an opportunity to establish a systems integration company with the unique ability to provide IP network-based audio, video, data, security and telecom solutions, he formed Pentegra Systems with Greg Augspurger. Ed’s current responsibilities include overseeing the company’s sales and administration functions, including marketing, sales, human resources, and all financial operations.

Gregory Augspurger | P.E. | CTS | President

Greg Augspurger, a licensed professional engineer, had 30 years of experience in the systems integration business prior to establishing Pentegra Systems. His diverse background includes over 14 years at a leading systems integrator. He later founded CSE, an electronic systems company that developed a LAN-based media management system eventually acquired by Dukane Corporation. After the acquisition, he assumed the role of Executive Vice President and COO for Shure, a worldwide leader in microphones and audio electronics.

Greg’s current responsibilities include overseeing the operations of Pentegra, including design, engineering, project management, system assembly, test, installation, and ongoing service and support.


Our sales team can do far more than just talk selling points. The Pentegra team includes experienced, knowledgeable design engineers, capable of evaluating your system needs and designing a solution that will exceed your expectations. Our approach is to provide the best value over the long term. Whether your needs involve audio, video, data, security or telecom systems, our specialists in each of these technologies will work together to formulate a multi-discipline solution that perfectly meets your needs.


From order receipt to end-user training, our Operations Team turns your proposed system into reality.

First, a Project Manager is assigned to coordinate the design and implementation of your system. These individuals often come from the installation side of our business, so they have extensive experience with the tasks required to properly coordinate any size project.

System Engineers, all highly trained and experienced, take the design proposed by the sales team and create the detailed equipment list, block diagrams and other AutoCAD generated drawings to facilitate the procurement and installation of the system. They work hand-in-hand with the Project Manager to ensure that the system design meets the scope of the proposal or the specification.

Once the design is complete and material is procured, assembly shop technicians build the equipment racks and test the system before it is delivered to your facility.

Next, our factory-trained, I.B.E.W. Installation Team installs the system per the design drawings. The Project Manager and System Engineer will configure and test the system in the field. When testing is complete, the system is turned over to you. Either the Project Manager or System Engineer will provide you with comprehensive training. This entire process is coordinated by the Project Manager, to provide a system as proposed and on-schedule.


When your system has an issue, you need a team of field service technicians capable of diagnosing the problem quickly and addressing it as efficiently as possible. The Pentegra Service & Support Team has extensive experience resolving system problems and minimizing your downtime, for audio, video, data, security and telecom systems. Our engineers have the technical background, training and experience to recognize the cause of a problem and get your system back up and running in a very effective manner.
