Curtis Glassen

PRESIDENT

I chose to pursue a career in IT at the early age of 15. After five years in the industry, I partnered with TJ Haggerty, Inc. to form the company in 2006. In 2018 I then became the sole owner of Glassen Technology Services. My passions for organization and technology drive me to incessantly better myself and my employees, all while growing a successful business. When I find spare time, I enjoy boating, hiking, and experimenting in the kitchen.


Moe Shittu

SUPPORT & SERVICE MANAGER

It all began at the age of seven, when I drove my parents crazy building an intruder alarm on a circuit board. Since then, I've moved up to programming and creating iOS apps in my free time. My curiosity for testing new software and the latest OS leave the functionality of personal PC in a perpetually unknown state. Fun Fact: I brew beer.


Chad Klamer

FIELD ENGINEER

My IT interests began in 1984, when my family bought a Commodore 64. I recall loading games on 5.25 floppy disks like it was yesterday. Since Getting my BS from UW Stout in Telecomm and Business Management, I've spent 13 years supporting businesses' IT needs. You'll find that I do a majority of the non-remote client support as I enjoy being hands-on. In my free time, I'm with my wife and two boys, often fishing, boating, and gardening.


lynn schattner

SENIOR ENGINEER

I've acquired a BS in Information Technology, MS in Information Systems and Technology Management with a specialization in Information Assurance and Security, and I'm currently working on my Doctorate in Information Technology, specializing in Information Security. I'm highly experienced in technology infrastructure, information security, and cloud computing. Fun Fact: I am a licensed amateur radio operator.


Chris Wagner

SUPPORT ENGINEER

I am a network specialist with multiple years of experience in configuring backups, cyber security, and management of workstations, Windows, and third-party software. I have an Associate of Applied Science from WCTC. Prior to IT assisting, I was an assembly technician, building hardware much like the kind I now service. In Contrast to my "techie" side, I also skateboard, create stained glass, and enjoy traveling.


Kari Hegemann

Administrative Assistant

My administrative experience began in 2013 where I found my knack for helping others and learned the importance of knowing all sides of a company to make it work most efficiently. I was quickly drawn to the accounting aspect of an organization and have enjoyed continually learning new technology associated with it.
When I am not at work, I enjoy spending time up north with family and friends on our utv in the summer and snowmobiling in the winter.


Keegan Richards

Tier II Technician

I became interested in technology at a very young age. I remember getting electronic games in McDonald's Happy Meals and I would figure out how to play, no instructions needed. I graduated with a BBA in IT in 2019, while competing collegiately in Track and Field at the University of Wisconsin-Whitewater. Off-hours you can find me fishing, snowboarding, watching sports, and touring craft breweries.
