"Big brands are like newspapers and magazines, they need an editor in chief"
Nizan Guanaes

Sergio Fontes, former director of the National Observatory

"Recently appointed Director of ON, I was introduced by a friend to the Cellera partners and was soon on the covers of the two main economic newspapers in Brazil, Valor and the now extinct Gazeta Mercantil. The Cellera team has always demonstrated in-depth knowledge of our activities. We are responsible for measuring the official time in Brazil and for several projects in the areas of geophysics and astronomy. With less than two years of work, ON became a record holder in media exposure, among all MCTI institutes."
