Recommendations



Technology Instructor - University of Utah

Christer is an excellent instructor. He not only works well with the staff when preparing for his classes, but he thinks beyond the obvious to bring novel and highly effective solutions to any problems that arise. He is also flexible, willing to work with his students to be sure they have the best experience in the class possible.

- Jeremy Robb, Technology Instructor, University of Utah


Systems Engineer - Partnet, Inc.

I've had the opportunity to work with Christer twice. Once when we were both working at Guru Labs and then again when the project I was assigned at NexOne included working with Partnet. I have been very impressed with his talents and the work he does. I found him to be an honest, no-nonsense, straight forward, get the job done sort of person which is I consider a positive quality to have in an IT environment. Christer also has takes a great interest in his field (Linux, System Administration, etc.) outside of work, and he actively participates in local and worldwide communities..

Linux Instructor - Guru Labs

Christer is a dedicated, hard-working and loyal colleague. I value his opinion when I ask. He provides timely and useful answers with research and results to back up his claims. Christer provides a very good vibe around the office and with our other colleagues. He's always positive and interested in helping those around him succeed, no matter what the subject. He dedicates much of his personal time to making sure those who are interested have the knowledge he knows he can provide. Christer is an excellent instructor in my experience.
