About Coretek

Our consultants accelerate your vision, and our Smart Managed Services enable you to focus on your business. We deliver customer success, no exceptions!


The inspiration to build Coretek came from business experiences and lessons learned by Coretek's founding leadership. Ron Lisch, Ray Jaksic, and Clint Adkins spent years working at enterprise IT integration and consulting organizations in the late 1990s and early 2000s.

Ron and Ray both became disenfranchised with the numbers-only driven decisions at their companies. In 2003, Ron left to pursue a career in commercial property development, and in 2004 Ray went to work inside an internal Healthcare IT department.

In early 2005, Ron became passionate about starting an IT consultancy business where talented and intelligent people could work with other great people! So in May of 2005, Coretek Services, Inc. was born, and by July 1st, Ray had quit his job and joined Ron working full time with Coretek. Clint joined full-time at Coretek in November that same year.

The initial approach to success for Coretek was simple: Make sure customer projects are successful, no exceptions! And how did Coretek ensure that customers' projects are always successful? That answer is also simple: Hire the best people. These mantras evolved into Coretek's mission and vision statements:

Mission: Customer Success, No Exceptions!
Vision: To create a culture that attracts great people who want to work with other great people and do great work!
The mission and vision statements are the foundational cornerstones that drive the success of Coretek to this day. Learn about our values.
