Participants refine, reinforce, and execute the Sandler system through weekly sessions that combine instructor-led learning, interactive roleplays, real-world coaching, and peer collaboration. While most sales seminars fade within 48 hours, Mastery creates lasting change. The program’s reinforcement-based model is built on proven adult learning principles, ensuring that new habits and techniques become second nature over time. - Public virtual classes with participants from different industries. Ideal for adding a new hire. - Virtual or onsite classes for customized, client specific needs. - Virtual Coaching Sessions - Self-paced learning and reinforcement through Sandler's Learning Management System - Virtual or onsite one or two day workshops that focus on specific topics or challenges.
