Built by Practitioners Focused on Results
Apex Field Performance Group was founded by commercial leaders who have lived the challenges your teams face every day.
Why We Started Apex Field Performance
Apex was created because founders Sherri Lee Ferstler and Robert Klein saw the same challenge across organizations: performance issues rarely stem from strategy — they stem from leadership capability, coaching quality, and execution discipline. Their shared belief that stronger leaders create stronger teams is the foundation of Apex's work.
Together, they offer organizations:
- Objective, experience-based evaluation of field performance
- Deep insight into DBM capability and leadership effectiveness
- Practical, actionable recommendations that can be implemented immediately
- A proven framework for strengthening execution, alignment, and accountability
Apex Field Performance Group exists to help companies build confident, capable leaders and high-performing field teams. With complementary strengths and a combined track record of leading at the regional and national level, Robert and Sherri provide the clarity, structure, and leadership insight organizations need to elevate performance and accelerate growth.
