David H. Sandler developed the Sandler Selling System® methodology, an innovative, non-traditional selling system, in the late 1960s, and created the concept of ‘reinforcement training’ to support it. From that foundation, he went on to create a series of proven sales training programs for small- and mid-sized companies and Fortune 500 corporations, and founded the Sandler Sales Institute®. We changed our name to Sandler Training in 2008, to more accurately reflect the diversity of our training offerings, which have expanded beyond sales training to include management, leadership, negotiating skills, customer service, as well as executive coaching and mentoring. We’ve grown into a organization that dominates the global training market, with more than 250 offices worldwide, providing instruction in 27 languages. Sandler provides training and consulting solutions for Fortune 500 companies and small- to medium-sized businesses through: Sales and sales management training, Management and Leadership training for business owners and senior executives, Negotiations training, Customer Service training, Coaching and Mentoring
