Our Team

Bruce Costello - President

bruce_costelloBruce is the founder of FourThirds and he’s on a mission to help sales teams to break free of the limitations of the incremental growth paradigm. This takes new thinking, new skills and new processes.

Part of that mission is to help sales teams transform without taking them away from their customers and boring them in a classroom. The best teams and the top performing individuals do “All the Basics-All the Time”. His focus is to help build the “complete” salesperson by not limiting them to a small subset of the skills and process. Instead he champions the concept of “Total-Selling”.

When the entire customer facing organization uses the same lexicon; when they use a comprehensive process; when their skills are kept sharp and not allowed to go dull over time and when they are pro-actively coached throughout the sales process and encouraged to break-away from the ordinary….that’s when break-out performance occurs.

Bruce is leading FourThirds to be the disruptor of the entrenched instructor-led classroom based sales-training industry by providing on-line development solutions for sales organizations that have a far higher return, provide a much broader and deeper solution set coupled with a radically different business model.

He formed FourThirds in 2006 with the aim of helping sales teams ‘raise their game’ through superior strategy, process, individual skills and execution.

“I coach CEO’s, sales leaders and sales teams in the methods that have been most successful during my career. What does ‘raising their game’ mean? Quite simply, winning more, losing less, avoiding the no-decisions and growing bigger deals.”
