For over 30 years, Brian has focused his career on the success of the U.S. Public Sector, growing and leading successful teams, building meaningful industry and Government relationships, and having fun along the way.  This focus has been realized across various leadership roles across the channel eco-system including technology manufacturers, value-added resellers, and distribution.

Most recently, Brian served as President of DLT Solutions and was instrumental in their growth to $1B+ and ultimately the successful sale to Tech Data in December 2019.  As President, Brian was responsible for driving DLT’s strategic initiatives to align with the dynamic technology landscape while addressing the value required by DLT’s channel partners and the Government customer.
