Sean and I worked together when I began my networking career with International Network Services (INS), which later was merged into Lucent Technologies. His command and understanding of networking technologies has been unmatched by anyone I have ever met.

When we worked together, he had obtained about 24 professional certifications in less than a year, and always knew more about a given technology than anyone else he worked with. Sean is dedicated to empowering himself and others he meets, and his ability to comprehend standards, white papers, and courseware is immense.

I would not only gladly work with him again, but I would also know I had an expert around that I could learn something from.
