Luis Silva

Administrative Manager & technique

“A customer is the most important visitor to our premises. He does not depend on us. We are dependent on him. He is not an obstacle in our work. He is the objective. He is not a stranger to our business. He is part of it. We do not do him a favor by serving him. He does us the favor by giving us the opportunity.”

Manuel Soares Silva

Technical manager

“Being on a level playing field in terms of price and quality only gets you into the game. Service is what will win you the game.”

Elsa Silva

Administrative assistant

“The customer never buys a product. By definition, the customer buys the satisfaction of a need. He buys a value.”
