AVANT's World Class Engineers
Niko O'Hara
VP of Programs, Engineering & Vendors
As the first engineer at AVANT in 2013, Niko was truly born in the cloud. He uses his technical background in Electrical Engineering to dissect complex technologies like SD-WAN/SASE, Backup/DR, and Security.
When I'm not working with the best engineers on the planet, you can find me at home with my wife and two French Bulldogs, watching Marvel movies, playing PS5, hosting game nights, or shooting hoops.
Andrew Pryfogle
VP of CX AI & Global Education Lead
A 30-year channel veteran and passionate advocate for the Trusted Advisor, Andrew is the founder of CX Effect, a specialty TSD acquired by AVANT in 2024. He also created CX LIFT, the industry’s premier CX AI conference, and continues to lead innovation at the intersection of customer experience and emerging technology.
The future of the channel lies at the intersection of intelligence and experience. My mission is to equip Trusted Advisors with both.
Chip Hoisington
VP of Connectivity & Colo
Chip brings more than 25 years of technology, engineering, and sales experience to the AVANT team. While he specializes in connectivity, global wide area networks, colo, TEM, and Mobility, Chip also holds certifications in Security, Data Science, and IT Support.
My colleagues would describe me as a story teller who uses analogies to simplify complex subjects. People say that I love to teach. When not working toward global domination, you can find me near the water fishing and teaching other people to fish.
Stephen Semmelroth
VP of Cyber Resilience
Stephen is a vCISO, CISSP, and Army Ranger who led cyber teams and infantry platoons in Afghanistan. After retiring from the Army, he founded and sold a cyber recruiting company.
Coming to AVANT allows me to roll up my sleeves and truly build the industry. This is an opportunity to grow the security program and allow TAs to be there when customers need them, and to build a plan that turns fear into rational planning and execution.
