Coretek has been providing world-class Microsoft-centric solutions for 15+ years. Our mission has always been to unlock the cloud’s true potential for our clients, strengthen their organizational security, and help them achieve quantifiable business results.
The story of Coretek begins when our founders, Ron Lisch, Ray Jaksic, and Clint Adkins, founded the company in 2005. After years of working in enterprise IT integrations and consulting, Ron Jay and Clint were inspired by the idea of creating an IT consultancy business where talented and intelligent people could thrive in an innovative and positive environment.
By hiring the best people for our team, we’ve been able to stay consistent with the guiding Coretek ethos: “Customer Success, No Exceptions!”
Ron is a native of Indiana, a graduate of Indiana University Bloomington's Kelley School of Business, and holds a degree in finance. Ron sharpened his finance skills in technical, sales, and leadership positions at Siemens and Unisys (formerly Burroughs). His broad experience positions him as a leader who truly understands the business and operations of IT services.
Ron also has a strong sense of community and a desire to pay it forward locally and globally. He sponsors the Coretek team as a volunteer with area food banks, home improvement projects through services like Rebuilding Together, blood drives, and 'adopt a family' programs. He also traveled on an international mission trip in 2019 to help build a Coretek-sponsored computer lab and training facility at a school in India.
Whether he’s helping customers, partners, employees, or the community, Ron lives and breathes Coretek's core focus — a commitment to building a culture that attracts and retains the best people. Outside of work, he loves boating, camping with kids, and mountain biking. He would love to take you to lunch, so introduce yourself early!
