Russ Levanway

Chief Executive Officer

Recently recognized in Pacific Coast Business Times "Who's Who in Business Leadership," Russ is a sought-after public speaker, technology expert, and community leader.

As co-founder and CEO of TekTegrity, this upstate New York native relocated to San Luis Obispo in 1996. During an 8-year stint in the IT department at Cuesta College, Russ gained a broad range of expertise including project management and technical implementation of complex equipment such as SANs. As the CEO of an ever-growing company, Russ hasn’t had many opportunities to perform tech work lately, and focuses on company strategy, finance, and human resources. His goal is to build a successful and sustainable business that provides incredible value for clients, and a great workplace for his team.

When not charting out the future for TekTegrity, Russ serves on several non-profit boards and is a past Board President at the San Luis Obispo Chamber of Commerce. He enjoys spending time with his two adorable daughters Alayna and Aviah and his wife Sarah, and training for his next 5k run. An interesting fact about Russ: He lost almost all of his hearing at the age of 4 due to spinal meningitis. Russ is one of only a few thousand people in the world who have bilateral cochlear implants.

John came to TekTegrity after spending ten years as a leader in Cuesta College's Information Technology Department where he helped make possible Cuesta's High Tech building, myCuesta portal, and Gmail integration.

If you come by our office and there are dozens of donuts, bagels or fresh egg rolls (from San José) in the break room, John is most likely the food fairy who left them. And if he’s not feeding or directing the tech team you might find John having lunch at the Elks Lodge or spot him cruising the coast with his motorcycle gang.
