Who We Are




With over 26 years of experience in IT and cybersecurity, Larry Pfeifer is recognized as a leader in helping people and organizations to solve their IT and security-related issues. As a proud New Jersey native, Larry joined the Navy in 1993 and started a career in IT. After serving his country, he held positions at Widener University, Nortel, Philadelphia Stock Exchange, BlueCoat Systems, and CrowdStrike. Working as an end-user, manager, engineer, sales engineer, account manager, and sales manager has given Larry a 360-degree view of all sides of IT. 

Larry started Consortium with one goal—helping people. His altruistic views came from organizing a feeding the homeless program in Camden, NJ. From there, he founded Consortium Networks as an avenue to continue to help its members, partners and others.

Larry resides in southern New Jersey and is active in his community, charities and family.
