Hi, I'm David Rosener.

With over two decades of experience in enterprise IT, I built Rosener Tech Services to bring corporate-grade network solutions to the small and medium-sized businesses that drive our local community.

My professional background is rooted in building and maintaining large-scale infrastructure. Previously, I served as a Network Administrator for Menards, and I currently work as a Network Engineer managing the infrastructure for a nationwide company with over 800 branch locations across the US. I know exactly what it takes to keep critical systems online, secure, and running flawlessly at scale—and I am passionate about scaling those exact same standards down to fit the budget and footprint of local businesses.

Outside of the server room, my life is centered around faith and my family. I have proudly called the Wisconsin area home for the last 20 years. My wife and I have been married for over two decades, and we stay plenty busy raising our four kids, ranging in age from 6 to 18. Whether I am designing a secure VPN for a client, smoking a brisket on the weekend, or spending time with the family, I believe in doing things right the first time.

I would love to connect and see how I can help streamline your IT.
