Who We Are 

As the Principal and founder of the Sandler Training in Oakland, CA, Joseph Diliberto transformed over 30 years of professional sales, sales management, marketing, strategic planning and public speaking experience into a career in sales coaching. His background includes executive level positions in Sales and Marketing with Fortune 100, Fortune 500 and start-up companies.

Introduced to the Sandler Training system of selling strategies while holding an executive position, Diliberto made the decision to become directly involved not only in the practice, but in the teaching of these skills.  Diliberto opened his Oakland, CA franchise office in 2004.

Since 2004, Joe has established his expertise in sales training in the San Francisco Bay Area with clients and through speaking engagements.  An active member of his business community, Joe trains professionals around the Bay Area and offers his services as a speaker for business organizations such as the Chambers of Commerce and Rotary clubs.

For more than 30 years, Sandler Training has been a leader in sales and sales management training. Sandler’s distinctive, non-traditional selling system and highly effective sales training methodology have helped salespeople and sales managers at every level take charge of the selling process. Sandler training is designed to create lasting performance improvement rather than the motivational quick-fix typical of many seminar-based training efforts. To do so, Sandler relies on reinforcement training – a system that combines quality review materials along with access to ongoing training workshops and individual coaching sessions.
