Dario Ramerini

The Humanist

Dario is one of the first persons to take interest in oneatatime. He has followed the development of the system and, used it for himself, and was one of the first to facilitate people in adopting the system.

Dario is an exceptional human being with a wide range of experience in many domains. He took charge of a jewellery company that was in great difficulty, and turned it around thanks to his intuition, practical wisdom, and hard work. He cleaned up the inventory, restructured the debts, renewed the relationship with customers around the world (Europe, USA, Russia, Emirates), and revived the value proposition. He saved the company.

But his heart is into people and purpose. He has written 2 books about the ceremony of sale and a comic to educate children to look for their own talent. He is actually launching a branding method he created with Elena Tavelli, for connecting the heart of a brand with the hearts of the customers. His humanist approach has been proven to be key in creating lasting intangible value propositions.

As a oneatatime trainer, expect him to win the hearts of the people he will facilitate, and to share his wisdom in philosophy, etymology, and classic literature to win the minds. You will notice how people readily build bonds and trust with Dario. Choose Dario if you want a consultant with a light gentle touch that earns lasting results.
