Leif Madsen is a graduate of the Telecommuncations Technology program from the Sheridan Institute of Technology and CEO of LeifMadsen Enterprise, Incorporated, a documentation and consulting firm specializing in Asterisk. He was one of the first Digium Certified Asterisk Professionals (dCAP), and assists with the Astricon conferences and trainings organized by IPsando, LLC.

Leif first took an interest in Asterisk while attempting to find a voice conferencing solution for himself and his friends. After someone suggested trying Asterisk, the obsession began. Wanting to contribute and be involved with the community, and noticing the lack of Asterisk documentation, he co-founded the Asterisk Documentation Project.
