Sales Strategy · Sales Leadership · Business Growth

Curt Tueffert believes great sales organizations don’t happen by accident. They are built on purpose. For more than 40 years, he has sold, led sales teams, built sales organizations, trained sales leaders, and advised business owners.

As Vice President of Sales Development at DXP Enterprises, a Houston industrial distributor with about $2 billion in sales, Curt went from leading a $100M sales organization to building company-wide sales strategy and training programs. Those programs include DXP University and the DXP Sales Gym.

He designs sales processes, sets revenue targets, fixes broken pipelines, and coaches sales teams. He also brings tools he built himself, including ConnectDeck and the Peak Sales Strategy framework, and he wrote 5 Stones for Slaying Giants.
