About Terry Sisco

Helping Business Owners Hire Smarter, Sell More, and Build Winning Teams

Terry Sisco brings over five decades of proven leadership in driving sales and scaling performance. From 1974 to 2000, he rose through the ranks of national retail brands—starting in a single fine jewelry department and advancing to Senior Vice President over 150 stores and more than 500 employees. His track record? Five consecutive years of double-digit sales growth, followed by a corporate promotion to lead national advertising and sales promotion.

In 2000, Terry founded Exsellerate, Inc. to bring big-brand strategy and behavioral science to independent and mid-sized businesses. He’s built sales systems and training programs for world-class names like Maurice Lacroix, Platinum Guild International, and Blue Nile’s global call centers—alongside hundreds of high-performing independent jewelers and retail organizations.

But the turning point came during a training session at Blue Nile. Terry had an insight that changed everything:
"Why work to turn a 4 into a 6, when you could hire a 9 or 10 from the start?" That moment sparked a new mission—helping business owners consistently hire top performers, not fix underperformers.

Terry became a Certified Professional Behavior Analyst in 2005 and soon after created the Sisco Sales Score—a behavioral benchmark now used across the fine jewelry industry to predict top performers with 92% accuracy.

From that foundation, Terry has administered behavioral assessments and benchmarked the performance of thousands of potential and current team members.

Today, Terry and the Exsellerate team help business owners build high-performance sales teams—through smarter hiring, clearer performance metrics, and practical, behavior-based tools that drive results.
