"For me, nature is the great example to follow when it comes to elegance, efficiency, technology and management. I admire people who choose new and ecologically better ways in spite of resistance. SIGA is a great opportunity and a challenge for me to take that path in the interest of our customers, our employees and those that come after us."

"My main aim is to live each day with my family, in my professional and personal life with awareness and joy. I like people who have a vision that they put into practice. I am happy when we succeed in eliminating an old, highly polluting product from the market with a new, ecologically optimised one."
