Why Work With Me?

I am a long-time networking expert with more than three decades of international experience in IT consulting and training. My CCIE number is 1561. I passed the CCIE lab in 1995, when CCIE numbers were still extremely rare worldwide.

For more than 22 years I conducted world-renowned CCIE Bootcamps and prepared engineers from many countries for one of the most demanding certifications in the networking industry.

"The best CCIE Boot Camp Worldwide is run by a German guy named Heinz Ulm in Augsburg."
